In this paper, we provide a historical overview of the observation of quantum effects in both experimental and theoretical nanoscale devices. This overview puts into perspective the need for developing and using the Schred tool when modeling nanoscale devices. At the end of the document, we...
ECE 539 Report: Study of two-dimensional Shrodinger-Poisson Solver
01 Jun 2009 | Downloads | Contributor(s): Fawad Hassan
We solve the 2-Dimensional Shrodinger-Poisson system of equations using a self consistent scheme (like Gummel Iteration). We study a double gate Silicon Mosfet oriented in the 100 direction using the above setup. We assume a simple 6-valley bandstructure for Silicon.
