Self-Heating Effects in GaN/AlGaN Heterostructure Field-Effect Transistors and Device Structure Optimization

Filippov K.A., Balandin A.A., University of California Riverside, US

In this paper we present results of our simulation of temperature rise in GaN/AlGaN HFETs characterized by different geometry, layered structure, doping density and substrate type. We do note make simplifying assumptions of the uniform [...]

Carrier and Phonon Spectrum in Quantum Dot Superlattices for Optoelectronic and Thermoelectric Applications

Lazarenkova O.L., Balandin A.A., University of California Riverside, US

Quantum dot superlattices, e.g. multiple arrays of quantum dots, have been proposed for optoelectronic and thermoelectric applications. In this paper we present two models for calculating carrier spectrum in regimented three-dimensional (3D) quantum dot superlattices [...]

Electric Field Induced Self Assembly of Polymer Structures

Yang M., Ozkan C.S., Gao H., University of California Riverside, US

We have developed a method for fabricating polymer microstructures based on electric field induced self assembly and pattern formation. A dielectric fluid placed in between to conductive plates experiences a force in an applied electric [...]

Modeling and Optimal Design of High Sensitivity Piezoresistive Microcantilevers for Biosensing Applications

Yang M., Zhang X., Ozkan C.S., University of California Riverside, US

We discuss the mechanical design and optimization of piezoresistive microcantilevers for use in detecting changes in surface stress upon analyte-receptor binding. Conventional microcantilevers are used along with an optical detection system in many commercially available [...]
