Diode Parameter Extraction by a Linear Cofactor Difference Operation Method

Ma C., Li B., Liu F., Chen Y., Zhang L., Zhang X., Liu F., Feng J., He J., Zhang L., Zhang X., Peking University, CN

The direct extraction of the key static parameters of a general diode by the new method named Linear Cofactor Difference Operator (LCDO) method has been carried out in this paper. From the developed LCDO method, [...]

A Continuous yet Explicit Carrier-Based Core Model for the Long Channel Undoped Surrounding-Gate MOSFETs

Zhang J., Zhang L., He J., Liu F., Zhang J., Zhang L., Feng J., Ma C., Peking University, CN

An explicit carrier-based core model for the long channel undoped surrounding-gate MOSFETs is presented in the paper An analytic approximation solution to the carrier concentration is developed from a simplified Taylor expansion of the exact [...]

Numerical Analysis on Si-Ge Nanowire MOSFETs with Core-Shell Structure

Fu Y., He J., Liu F., Zhang L., Feng J., Ma C., Peking University, CN

This paper investigates the transport properties of the silicon/Germanium nanowire MOSFETs with core-shell structure by a numerical method. Coupling Poisson’s equation to Schrödinger’s equation for electrostatics calculation, and electron structure to current transport equation for [...]

Targeting Nanoparticle Probes to Differentiating Stem Cells

Cabral-Teixeira J., Benjamin K., Zhang L., Maurer J., Tsuda M., Chao Y.S., Prigozhina N., Price J., Snyder E., Mercola M., Ruoslahti E., West M.D., Larocca D., Advanced Cell Technology, US

Pluripotent stem cells offer great potential for treating diseases where cells are lost to injury or disease processes. The ability to specifically label progenitor cells in populations of differentiating stem cells will provide a powerful [...]

Euler Buckling of Individual SiGe/Si Microtubes

Zhang L., Dong L.X., Bell D.J., Nelson B.J., Schönenberger C., Grützmacher D., Paul Scherrer Institut, CH

Freestanding Si/SiGe microtubes have been fabricated using the roll-up technique of strained bilayer structures. Si/SiGe bilayers of 18 nm thickness have been rolled into tubes of 1.3 μm diameter. Tubes of 60 μm length have [...]

Nanofiber Structures as Mimics for Cellular Membranes

Doktycz M.J., Zhang L., Melechko A.V, Klein K., McKnight T.E., Britt P.F., Guillorn M.A., Merkulov V.I., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We are investigating the use of vertically aligned carbon nanofibers (VACNFs) as a material for controlling molecular transport in a manner analogous to natural cell membranes. VACNFs can be synthesized with nanometer scale dimensions, can [...]

Controlled Synthesis and Directed Assembly of Vertically Aligned Carbon Nanofibers for Functional Nanoscale Devices

Merkulov V.I., Melechko A.V, Guillorn M.A., McKnight T.E., Austin D.W., Hale M., Zhang L., Yang X., Hensley D.K., Subich T., Doktycz M.J., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

The controlled synthesis and directed assembly of materials at the nanoscale remain two of the most difficult challenges for the realization of functional nanoscale devices. For example, while there has been a great deal of [...]
