Complete Surface-Potential Modeling Approach Implemented in the HiSIM Compact Model Family for Any MOSFET Type

Miura-Mattausch M., Miyake M., Kikuchihara H., Feldmann U., Amakawa S., Mattausch H.J., Miura-Mattausch M., Hiroshima University, JP

Many possible future device structures are investigated in parallel to obtain highest performance features. It has been shown that an SOI-MOSFET with a thin body enables both high device performances and suppression of statistical variations. [...]

Calculated Production Yields in Metallofullerene Series

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

The paper reports computations for all lanthanoids L on their encapsulation into the only C74 IPR (isolated pentagon rule) cage (L@C74), for Z@C82 based on encapsulation into the IPR C2v C82 cage, and also for [...]

Simulation of Field-Plate Effects on Surface-State-Related Lag and Current Slump in GaAs FETs

Tanaka T., Itagaki K., Nakajima A., Horio K., Shibaura Institute of Technology, JP

In this study, we carry out two-dimensional transient analysis of field-plate GaAs MESFETs by taking surface states into account. Quasi-pulsed current-voltage curves are derived from the transient characteristics. We show that drain lag and current [...]

Effects of Ag and Pd Addition on Mechanical Property and Ion-migration Tolerance in Low Temperature Sintering Bonding Using Ag2O Paste

Hirose A., Itou T., Ogura T., Osaka University, JP

We have proposed a new bonding process using Ag2O paste composed of Ag2O particles mixed with reduction agent of triethylene glycol (TEG). Ag nanoparticles formed at around 130℃ to 160℃ through the reduction process. Such [...]

The interpretation of the conventional superconductivity on the basis of hypothesis of small polaron

Inoue A., Japan Atomic Energy Agency, JP

The mechanism of conventional superconductivity is well-known to be able to be explained on the basis of BCS theory which is based on the ambiguous correlation between a normal state and superconductive state of metals. [...]

Theoretical Modeling of Phase Diagram of Clathrate Hydrates toward Hydrogen Storage Applications

Belosludov R.V., Belosludov V.R., Mizuseki H., Subbotin O.S., Belosludov R.V., Belosludov V.R., Kawazoe Y., Institute for Materials Research, Tohoku University, JP

The possible formation of hydrogen hydrate, a class of inclusion compounds consisting of water and hydrogen as host and guest molecules, respectively, with different structures by adding various guest molecules suggests the practical feasibility of [...]

Cell adhesion behaviors on polyethylene terephthalate surface modified by surface-wave plasma-initiated graft polymerization

Nina A., Ishizaki T., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

For better performance in biomedical applications, the PET surface still needs to be improved by functionalization, particularly controlling the hydrophilicity. In order to impart hydrophilicity to the PET surface, we tried to introduce acrylic acid [...]

On-demand release of corrosion-inhibiting molecules from layerd double hydroxide film formed on magnesium alloy

Ishizaki T., Teshima K., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

Magnesium is one of the lightest engineering materials. Thus, it is expected that magnesium and its alloys are applied to aerospace, aircraft, automobile, and railway. However, they have a defect which is extremely low corrosion [...]

Development of the high performance GFRP with multiwall carbon nanotubes

Tarumoto N., Hodogaya chemical Co., Ltd, JP

Owing to the structural and mechanical properties of multiwall carbon nanotubes (MWCNTs), composites of MWCNTs are studied. However there is are few reports describing that MWCNTs without chemical modification is effective to mechanical properties of [...]

Development of high performance MWCNTs-dispersed-media

Tarumoto N., Hodogaya chemical Co., Ltd, JP

Owing to the superior structural, electrical and mechanical properties of carbon nanotubes, many potential applications, such as electric conductive plastics, electromagnetic absorber, heater, lithium ion battery, heat sink and high strength composites have been proposed. [...]
