Developing PbSe/PbS Core-Shell Nanocrystals Quantum Dots (NQDs) for Light Emitting NQD/Silicon Heterojunctions

Xu J., Xu S., Cui D., Xu J., Xu S., Paradee G., Zhang F., Zhu T., Pennsylvania State University, US

In order to incorporate infrared colloidal nanocrystal quantum dots into silicon matrix to develop silicon-based light emitters, we report in this paper the epitaxial growth of PbS shells over PbSe NQDs with monolayer precision. The [...]

Monte Carlo Transport Calculations of Strained SiGe Heterostructures from Ab-Initio Band-structures

Zorman B., Krishnan S., Vasileska D., Xu J., Van Schilfgaarde M., Arizona State University, US

The continued scaling of semiconductor devices creates numerous challenges which have to be overcome in order to achieve device behavior that satisfies speed and power constraints. Possible alternatives to conventional CMOS devices include strained-Si or [...]

Ultramicro Protein Arrays for Cytokine Detection

Radke K., Ryckman K., Nettikadan S., Lynch M., Mosher C., Xu J., Henderson E., BioForce Nanosciences, Inc., US

Several solid phase microarray based methods for the detection of the genomic materials have been developed based on amplifying the target molecules. Since proteins cannot be amplified, a similar approach to protein detection faces some [...]

Functional Nanoarrays for Protein Biomarker Profiling

Lynch M., Mosher C., Huff J., Nettikadan S., Xu J., Henderson E., BioForce Nanosciences, Inc., US

The success of microarrays for analyzing nucleic acid and, more recently, protein-protein interactions illustrates the advantages of bioassay miniaturization. However, the current level of miniaturization of useful bioanalytical tools still creates limits in terms of [...]

Compact Modeling of Bistable Electrostatic Actuators

Xu J., Darling R.B., Lauritzen P.O., University of Washington, US

A compact circuit simulation model for a bistable electrostatic cantilever actuator is presented which is appropriate for circuit and system simulation of RF MEMS switches. This simplified model captures the essential physical features of a [...]
