Modeling and Optimization of Polymer Based Bulk Heterojunction (BH) Solar Cell
15 Feb 2010 | Online Presentations | Contributor(s): Biswajit ray
A polymer phase separation model based on Cahn-Hilliard equation and a three-dimensional (3D) coupled exciton/electron/hole transport model in the disordered, phase-segregated morphology so generated, allow us to predict, possibly for the first time, the morphology dependent performance limits of...
All-Spin Logic Devices
19 Jul 2012 | Online Presentations | Contributor(s): Behtash Behinaein
We propose a spintronic device that uses spin at every stage of its operation: input and output information are represented by the magnetization of nanomagnets which communicate through spin-coherent channels. Based on simulations with an experimentally benchmarked model we argue that the device...
Simulation of the Spin Field Effect Transistors: Effects of Tunneling and Spin Relaxation on its Performance
05 Apr 2010 | Online Presentations | Contributor(s): Yunfei Gao
A numerical simulation of spin-dependent quantum transport for a spin field effect transistor(spinFET) is implemented in a widely used simulator nanoMOS. This method includes the effect of bothspin relaxation in the channel and the tunneling barrier between the source/drain and the channel....
Nonequilibrium Green’s functions theory: Transport and optical gain in THz quantum cascade lasers
26 Mar 2010 | Online Presentations | Contributor(s): Tillmann Christoph Kubis
Quantum cascade lasers (QCLs) are promising sources of coherent THz radiation. However, state of the art THz-QCLs are still limited to cryogenic temperatures. The charge transport in these QCLs is subject to coherent quantum phenomena, such as quantum tunneling, confinement and interferences as...
Magnesium Phyllo (Organo) Silicate: A Clay to Play with in Materials Science
24 Apr 2012 | Online Presentations | Contributor(s): M. Eswaramoorthy
The synthesis and applications of amino functionalized clay will be discussed in this talk. The tailor made clay containing amino pendants is easily dispersible in water. This property has been effectively utilized to make water soluble clay-metal nanoparticles composites, clay-protein and...
