An Explicit Carrier-Based Compact Model for Surrounding-Gate MOSFETs

He J., Liu F., Bian W., Tao Y., Wu W., Lu K., Wang T., Chan M., Peking University, CN

An explicit carrier-based model for the undoped SRG MOSFETs has been developed by an accurate yet analytic carrier concentration approximation. This new explicit model requires no numerical iteration but more accurate and computation efficient, thus [...]

A Carrier-Based Analytic Model for Undoped Ultra-Thin-Body Silicon-on-Insulator (UTB-SOI) MOSFETs

He J., Bian W., Tao Y., Li B., Chen Y., Peking University, CN

A carrier-based analytical model for undoped (lightly doped) UTB-SOI MOSFETs is derived by solving the Poisson equation coupled to the Pao-Sah current formulation. It is also shown that the predicted I-V characteristics are in complete [...]

Analytical Solutions for Long-Wide-Channel Thick-Base MOS Transistors I. Effects of Remote Boundary Conditions and Body Contacts

Jie B.B., Sah C-T, Peking University, CN

Analytical solutions and computed characteristics for long-wide-channel thick-base MOS transistors are reported. The second generation industrial-consensus surface potential approach is used. Decomposition of the 2-Dimensional transistor problem into two 1-D problems follows the 1966-Pao-Sah current- [...]

High Conentration of Interface Traps in MOS Transistor Modeling

Chen Z., Jie B.B., Sah C-T, Xiamen University, CN

Modifications of the MOS capacitor and transistor characteristics by the presence of a high concentration of interface traps are described. Change or distortion of the gate/base voltage dependent characteristics are presented, such as the gate [...]

On-site Screening of Avian Influenza Virus (AIV) by Polystyrene Microfluidic Chip Immunoassay

Zhao Y., Zou M., Xue Q., Zhou P., The Chinese Academy of Inspection and Quarantine, CN

AIV Ag of A type with viral nucleoprotein (NP), which covers all AIV subtypes, including high-pathogenic AIV was determined by polystyrene microfluidic chip ELISA method. In micro-channels of chip instead of conventional 96-well microtiter plates, [...]

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Jiachang Y., Institute of Biophysics, Chinese Academy of Sciences, CN

Here we described a novel approach of CdTe quantum dots fluorescence probes to improve the detection of proton flux through F1F0-ATP by ATP synthesis. It was found that both the CdTe quantum dots (535nm, 585nm) [...]

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Zhang Y., Deng Z., Yue J., Tang F., Institute of Biophysics, Chinese Academy of Sciences, CN

The chromatophores allow self assemble with the negatively charged Qdots through electrostatic reaction. The fluorescence intensity of Qdots not only was vastly different in the solution and on the surface of chromatophores, but also for [...]

Multiplexed immunoassays by flow cytometry for detection of Clenbuterol, Chloramphenicol and sulfadimidine with high sensitivity and selectivity

Zhao Y., Zou M., Gao H., Xue Q., Zhou P., The Chinese Academy of Inspection and Quarantine, CN

An accurate, rapid and cost-effective detection on the environmental hazardous chemicals is the cornerstone of efficient food safe management. Hereby we discuss the relevance of an emerging technology, multiplexed competitive immunoassays read by flow cytometry, [...]

Thermal conductivity enhancement of carbon nanotube composites

Deng F., Zheng Q.-S., Tsinghua University, CN

Simple models for the thermal conductivity enhancements of carbon nanotube (CNT) composites are presented as analytical functions of volume fraction, anisotropic thermal conductivities, aspect ratio, non-straightness, and interfacial thermal resistance of the CNTs. The model [...]

The Effect of Starch Structure on Starch-based Nanocomposite

Zhou J.H., Hanna M.A., South China Agricultural University, CN

The effect of starch structure on starch based nanocomposite Starches, including high amylose cornstarch, normal cornstarch, and waxy cornstarch, were gelatinized and mixed with nanoclay aqueous dispersion and different amount plasticizer. The mixtures were then [...]
