Silicon Nanowire Metal-Oxide-Semiconductor Field Effect Transistor NBTI Effect Modeling and Application in Circuit Performance Simulation

Chan M., Du C., He J., He Q., Ma C., Wang W., Wu W., Ye Y., Zhang X., Zhao W., PKU-HKUST Shenzhen-Hongkong Institution, CN

A Negative Bias Temperature Instability (NBTI) model for the P-typed Silicon based nanowire MOS field effect transistor (SNWFET) and its application in the circuit simulation is studied in this paper. The model is derived from [...]

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

Fukunaga Y., Kikuchihara K., Mattausch H.J., Miura-Mattausch M., Miyamoto H., Zenitani H., 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 [...]

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

Isezaki Y., Nakaoki Y., Uno S., 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. [...]

The methodology and the software for the analysis of the atomic density modulation underneath the surface of a nanocrystal

Gierlotka S., Palosz B., Palosz W., Skrobas K., Stelmakh S., Institute of High Pressure Physics PAS, PL

Internal structure of nanocrystals can be extracted from Pair Distribution Function, which is obtained by Fourier transform of the diffraction data. Such a transform, G(r), contains complete information on inter-atomic distances present in the investigated [...]

Hybrid Materials made up of Ionic Liquids Confined in Porous Silica and Chalcogenide

Coasne B., Massobrio C., Ori G., Viau L., Villemot F., Vioux A., UMI CNRS / Massachusetts Institute of Technology, US

Hybrid materials made up of an inorganic porous material filled with a room temperature ionic liquid (IL) represent a novel class of materials with promising applications. The structure and dynamics of IL confined in amorphous [...]

Bi-Layer Graphene Nanoribbon Memory with Graphene Nanoflake Shuttle

Kang J-W, Kwon O-K., Lee J-H., Semyung University, KR

We investigated the dynamic properties of graphene-nanoribbon (GNR) memory encapsulating graphene-nanoflake (GNF) shuttle in the potential to be applicable as a non-volatile random access memory via molecular dynamics simulations. This work explicitly demonstrates that the [...]

A Generalized Model for Global Solar Radiation in South Africa Using Multiple Weather Elements as Predictors

Adeala A.A., Enweremadu C.C., Huan Z., University of South Africa, ZA

In this study a generalized model for predicting global solar radiation was developed for South Africa. This was achieved by employing easily measured weather elements like sunshine hour, ambient temperature, relative humidity and wind speed [...]
