Compact Model HiSIM-DG both for Symmetrical and Asymmetrical DG-MOSFET Structures

Ishimura K., Sadachika N., Kusu S., Miura-Mattausch M., Hiroshima University, JP

In this work, the circuit simulation model for DG-MOSFET named HiSIM-DG, has been developed based on the complete surface-potential-based description. The model solves the Poisson equation to the vertical direction iteratively in quasi-2 dimensions including [...]

HiSIM-SOI: SOI-MOSFET Model for Circuit Simulation Valid also for Device Optimization

Sadachika N., Kusu S., Ishimura K., Murakami T., Kajiwara T., Hayashi T., Nishikawa Y., Yoshida T., Miura-Mattausch M., Hiroshima University, JP

SOI-MOSFETs are considered to be suitable for high performance as well as low power applications and its developments are tend to go toward the thinner SOI films to enhance the device characteristics. Thus compact models [...]

Comprehensive Approach for Nanotechnology R&D and Public Engagement

Sekiya M., Ishizu S., An S., Tanabe T., Ata M., National Institute of Advanced Industrial Science and Technology (AIST), JP

AIST has participated in the research project “Development of comprehensive database index for a basis of facilitation of nanotechnology R&D” with the University of Tokyo and National Institute for Materials Science since September 2007. In [...]

Simulation of Decrease in Lag phenomena and Current Slump of Field-Plate GaAs FETs

Itagaki K., Ueda H., Terao Y., Horio K., Shibaura Institute of Technology, JP

Two-dimensional transient analysis of field-plate GaAs MESFETs is performed in which a deep donor “EL2” and a shallow acceptor are considered in a semi-insulating substrate, and the results are compared between the two cases with [...]

Computations on Encapsulations of Lanthanides into C74

Slanina Z., Nagase S., Institute for Molecular Science, JP

While the empty C74 fullerene has still not been available, various related C74-based metallofullerenes have been known and studied vigorously like Ca@C74, Sm@C74, Sr@C74, Ba@C74, La@C74, Eu@C74, Yb@C74, Sc2@C74 or Er3@C74. This contributions will deal [...]

Nickel oxide hollow nano-fiber electrodes for electrochemical capacitors

Machida S., Tsutsumi H., Yamaguchi University, JP

Morphology of electroactive materials in electrodes affects their electrochemical performance and capacity of energy storage devices. New architectures (3D) for electrodes and cells will overcome the traditional electrodes’ problems. However, preparation of 3D electrodes needs [...]

Characterization of poly(vinyl alcohol)-based composites prepared by electrospinning technique with in situ coffining process

Hara C., Tsutsumi H., Yamaguchi University, JP

A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. We propose new type reinforced polymer composites by electrospinning technique with in situ coffining [...]

CdSe nano-particles coated with thiol-terminated oligo(ethylene oxide)for protein targeting reagent

Ito Y., Tsutsumi H., Yamaguchi University, JP

Fluorescent labeling reagents are used as medical and biochemical research reagents that label specific protein, antigen, antibody, and DNA. However, the chromophoric groups (organic compounds) usually are not stable under long-time ultra violet (UV) excitation. [...]

Enhancement of Photocatalytic Cancer Cell-Killing Activity by Using Ag@TiO2 Core-Shell Composite Nanoclusters

Abdulla-Al-Mamun M., Yang H., Kusumoto Y., Kagoshima University, JP

The photocatalytic cancer cell-killing activities of the Ag@TiO2 core-shell composite colloidal nanoclusters have been investigated on HeLa cells killing under the UV-visible light irradiation. The Ag metal core-TiO2 shell (Ag@TiO2) composite nanocluster photocatalyst with uniform [...]

Ultra Accelerated Quantum Chemical Molecular Dynamics Study on Mechanochemical Reaction of Micro-Bubble Induced by Shock Wave

Hatakeyama N., Nomura A., Sasaki Y., Chiba K., Hata H., Hatakeyama N., Okushi K., Suzuki A., Koyama M., Tsuboi H., Endou A., Takaba H., Kubo M., Del Carpio C.A., Kitada M., Kabashima H., Miyamoto A., Tohoku University, JP

Mechanochemical reactions and micro-bubble formation may take place in water under strong compression/rarefaction realized by shock waves e.g. generated in collapsing process of laser-induced bubbles. However, elementary processes of the micro-bubble have never been revealed [...]
