Analysis of Breakdown Characteristics in Gate and Source Field-Plate AlGaN/GaN HEMTs

Onodera H., Hanawa H., Horio K., Shibaura Institute of Technology, JP

AlGaN/GaN HEMTs are now receiving great attention because of their applications to high-power microwave devices. It is known that the introduction of field plate enhances the power performance of AlGaN/GaN HEMTs, because the off-state breakdown [...]

Analytic Compact Model of Ballistic and Quasi-ballistic Cylindrical Gate-All-Around MOSFET Incorporating Drain-Induced Barrier Lowering Effect

Cheng H., Uno S., Nakazato K., graduate school of engineering, Nagoya University, JP

Gate-All-Around metal-oxide-semiconductor field effect transistors (GAA-MOSFETs) have been attracting ever-increasing attention. The numerical calculations including quantum mechanical effect and ballistic transport of drain current can be evaluated quite accurately. However, it takes an immense amount [...]

Modeling of Short-Channel Effect for Ultra-Thin SOI MOSFET on Ultra-Thin BOX

Miyamoto H., Fukunaga Y., Zenitani H., Kikuchihara K., Mattausch H.J., Miura-Mattausch M., Miura-Mattausch M., Hiroshima University, JP

The SOTB-MOSFET (ultra-thin film SOI layer on ultra-thin BOX) is a candidate for the next MOSFET generations with advanced technology due to its suppression of the short-channel effect. Besides, the thin box layer can well [...]

Monte Carlo Simulation of Electrochemical Detection of Redox Molecules with Nanoscale Redoxcycling

Zhu P., Iwahara S., Nakazato K., Uno S., Ritsumeikan University, JP

Biosensors that can detect minute quantities of important redox molecules in the human body are increasingly gaining attention nowadays. Currently, electrophoresis,fluorescence and amperometric detection methods are the common techniques used for such purpose. The previous [...]

Analytic and Numerical Modeling of Glucose-fueled Enzymatic Biofuel Cell Performance

Uno S., Nakaoki Y., Isezaki Y., Ritsumeikan University, JP

Fuel cells have been drawing increasing attention due to their high efficiency and harmless gas emission. Hydrogen is the most widely used fuel, but its safe storage and transportation is one of the main issues. [...]

Biodegradable Polymer-Based Composite Particles for Targeted Drug Delivery Carriers with Magnetic Response

Kitamoto Y., Oka C., Ushimaru K., Tsuge T., Horiishi N., Tokyo Institute of Technology, JP

Core–shell composite particles with biodegradability and magnetism were prepared for targeted drug delivery based on magnetic guidance. The composite particles were composed of a core of biodegradable polymer and a shell of assembled magnetic iron [...]

Shell Thickness Control of Mesoporous Silica Hollow Capsules and Their Release Behavior

Yamaguchi Y., Kato N., Meiji university, JP

we propose the method to control the shell thickness of the mesoporous silica hollow capsules (MSHCs) and the method to load the materilas into the MSHCs. The release behavior was also invesitgated. The template-assisted method [...]

Electrochemical Detection of Alcohol using Enzyme Sensor with Chromatography Paper and its Potential Application as halal Sensor

Musa M.S., Kuretake T., Harada Y., Hori F., Uno S., Ritsumeikan University, JP

The Islamic law forbids Muslims from consuming food that contains porcine derivatives and alcohol, among others. The halal term is not limited to only the food ingredients but also considers the absence of non-halal species [...]
