  • Non-equilibrium Green function method: theory and application in
           simulation of nanometer electronic devices

    • Authors: Van-Nam Do
      First page: 033001
      Abstract: We review fundamental aspects of the non-equilibrium Green function method in the simulation of nanometer electronic devices. The method is implemented into our recently developed computer package OPEDEVS to investigate transport properties of electrons in nano-scale devices and low-dimensional materials. Concretely, we present the definition of the four real-time Green functions, the retarded, advanced, lesser and greater functions. Basic relations among these functions and their equations of motion are also presented in detail as the basis for the performance of analytical and numerical calculations. In particular, we review in detail two recursive algorithms, which are implemented in OPEDEVS to solve the Green functions defined in finite-size opened systems and in the surface layer of semi-infinite homogeneous ones. Operation of the package is then illustrated through the simulation of the transport characteristics of a typical semiconductor device structure, the resonant tunn...

  • Bactericidal activity and silver release of porous ceramic candle filter
           prepared by sintering silica with silver nanoparticles/zeolite for
           water disinfection

    • Authors: Thuy Ai Trinh Nguyen; Van Phu Dang, Ngoc Duy Nguyen, Anh Quoc Le, Duc Thanh Nguyen Quoc Hien Nguyen
      First page: 035001
      Abstract: Porous ceramic candle filters (PCCF) were prepared by sintering silica from rice husk with silver nanoparticles (AgNPs)/zeolite A at about 1050 °C to create bactericidal PCCF/AgNPs for water disinfection. The silver content in PCCF/AgNPs was of 300–350 mg kg −1 determined by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and the average pore size of PCCF/AgNPs was of 50–70 Å measured by Brunauer–Emmett–Teller (BET) method. The bactericidal activity and silver release of PCCF/AgNPs have been investigated by flow test with water flow rate of 5 L h −1 and initial inoculation of E . coli in inlet water of 10 6 CFU/100 mL. The volume of filtrated water was collected up to 500 L. Results showed that the contamination of E . coli in filtrated water was

  • Dispersion and attenuation of surface plasmon polariton at
           metal–dielectric interface

    • Authors: Bich Ha Nguyen; Van Hop Nguyen
      First page: 035002
      Abstract: In the present work the behavior of a monochromatic electromagnetic wave propagating along the interface between dielectric and metallic media was rigorously studied. The exact analytical expressions of the electric and magnetic fields were derived. On the basis of the experimental data of the frequency dependent optical parameters of the media the dispersion and the attenuation of the surface plasmon polariton were determined by means of the numerical calculations

  • Solution processing of microcavity for BioMEMS application

    • Authors: Vu Nam Luong; Yoshiaki Ukita, Yuzuru Takamura, Tadaoki Mitani, Tatsuya Shimoda, Thi My Dung Dang Mau Chien Dang
      First page: 035003
      Abstract: Compared to the conventional silicon-based technology, the solution process appears to be a revolution in the field of micro/nanofabrication due to its advantages of high efficiency in material and energy consumption and the use of low cost material. In this paper, we introduce a new approach to fabricate BioMEMS devices using this novel technology to make microcavity. Zirconium oxide patterns were formed on the silicon substrate simply by spin coating its precursor and thermal imprinting technique. We used poly-propylene carbonate (PPC) for the sacrificial material due to its unique pyrolysis property. The PPC was coated on the ZrO patterns and excess film was etched by oxygen plasma but retaining PPC structure between the lines of ZrO pattern. Then another ZrO layer was coated to encapsulate the PPC. The final microcavity structures were obtained by just baking the substrate by pyrolyzing the PPC. The obtained results show the approach’s prospect of becoming an ideal alternativ...

  • Quantum theory of plasmon energy spectra in electron gases of bulk metal
           and metallic nanostructures

    • Authors: Van Hieu Nguyen; Bich Ha Nguyen
      First page: 035004
      Abstract: The present work is an attempt to formulate the quantum theory of plasmons in metallic structures starting from basic laws of electrodynamics and quantum theory as first principles. In particular, the dynamical integral equation of plasmon in any metallic structure was established. As a test, this general dynamical equation was used to determine the dispersion of plasmon in bulk metal and the obtained result completely agreed with the formula derived in conventional theories. Then the general method for determining the energy spectrum of plasmons in any metallic nanostructure was presented.

  • Functionalization of reduced graphene oxide by electroactive polymer for
           biosensing applications

    • Authors: Le Huy Nguyen; Tuan Dzung Nguyen, Vinh Hoang Tran, Thi Thu Huyen Dang Dai Lam Tran
      First page: 035005
      Abstract: A novel biosensing platform was designed by the functionalizing reduced graphene oxide sheets (rGO) with electroactive copolymer juglone. The composite film showed well-defined, stable electroactivity in a biocompatible buffer medium. Square wave voltammetry is used to record the redox signal for DNA hybridization. Current increase upon hybridization ( signal - on ) evidenced that short DNA target as well as polymerase chain reaction (PCR), so called ‘real sample’ products, related to different lineages of Mycobacterium tuberculosis strain. The signal - on reached ∼40% with 1 nM of short DNA (25 mer) target, while PCR product (Africanum, EAI and Beijing strains) produced a current change of ∼20%.

  • Study of RF performance of surrounding gate MOSFET with gate overlap and
           underlap

    • Authors: Angsuman Sarkar
      First page: 035006
      Abstract: In this paper a simulation study is used to investigate the RF performance of surrounding gate (SRG) MOSFET. The effect of nonsymmetrical gate structure caused by non- ideality in fabrication process has also been taken care into consideration. The important RF figure-of-merits such as unity-gain cut-off frequency f T and maximum operating frequency f MAX are studied with the help of a 2D device simulator. Their trends related to the variation of different design parameters such as radius, oxide thickness, gate length, and doping along the downscaling have also been reported.

  • Tunable morphological properties of silver enriched platinum allied
           nanoparticles and their catalysed reduction of p-nitrophenol

    • Authors: Joseph Adeyemi Adekoya; Enock Olugbenga Dare Michael Adediran Mesubi
      First page: 035007
      Abstract: A robust polymer based and polyol mediated procedure to synthesize nanobimetallic particles has been modified to produce core–shell and alloy Ag/Pt nanoparticles with tunable properties. Novel three-dimensional (3D) quasi nanocubes entangled in nanowebs were produced by rapid solution phase transformation with hot addition of absolute ethanol. The optical characterization showed extinction of plasmon resonance band occurring with incremental feeding ratio of Pt source in all cases. Transmission electron microscope (TEM) and high resolution transmission electron microscope (HRTEM) images revealed that the shape, size and size distribution of as-prepared silver platinum nanoparticles depended on the stabilizer or capping agent, mole ratio of metal ion sources, temperature and time of reaction. Meanwhile, catalytic activity was highest in the reduction of p-nitrophenol in the presence of polyvinylpyrrolidone/diethylene glycol stabilized Ag/Pt nanoparticles.

  • Shallow chemical bath deposition of ZnS buffer layer for environmentally
           benign solar cell devices

    • Authors: R K Choubey; Sunil Kumar C W Lan
      First page: 025015
      Abstract: Zinc sulfide (ZnS) thin film was grown by a shallow chemical bath deposition (SCBD) technique. In this technique a highly conducting hot plate was used to heat the substrate, while higher thermal gradient was achieved by a shallow bath of the ZnS solution. Consequently, homogeneous nucleation is reduced and quality of ZnS thin films can be improved by shaking. The main advantage of this technique over a traditional one is that the use of solution can be reduced greatly, which is crucial for cost reduction in practice. The effects of shaking on growth kinetics and film properties were investigated by characterizing the as-grown ZnS thin films by x-ray diffraction, transmittance and scanning electron microscopy (SEM).

  • Mulberry leaf extract mediated synthesis of gold nanoparticles and its
           anti-bacterial activity against human pathogens

    • Authors: K Adavallan; N Krishnakumar
      First page: 025018
      Abstract: Gold nanoparticles (Au-NPs) were synthesized at room temperature using Morus alba (mulberry) leaf extract as reducing and stabilizing agent. The development of plant mediated synthesis of nanoparticles is gaining importance due to its simplicity, low cost, non-toxicity, eco-friendliness, long term stability and reproducible aqueous synthesis method to obtain a self-assembly of nearly monodispersed Au-NPs. The formation and morphology of biosynthesized nanoparticles are investigated with the help of UV-Vis spectroscopy, dynamic light scattering (DLS), transmission electron microscopy (TEM), atomic force microscopy (AFM), x-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR) techniques. Au-NPs formation was screened by UV-Vis spectroscopy through color conversion due to surface plasmon resonance band at 538 nm for Au-NPs. DLS studies revealed that the average size of Au-NPs was 50 nm. TEM studies showed the particles to be nearly spherical with few irr...
