James Charles: Non-Local Scattering with a New Recursive Nonequilibrium Green’s Function Method


International Workshop on Computational Nanotechnology; Windermere, England, U.K., Jun 7, 2017

Nano is now

Soon our devices will depend on transistors that are a few atoms wide. A tool developed by the Nanoelectronic Modeling Group will help design them.If you think nano-devices are the stuff of science fiction or the distant future, think again. “If you have an iPhone or other smartphone, you already have nanotechnology in your pocket,” says Gerhard Klimeck, director of the Network for Computational Nanotechnology and professor of electrical and computer engineering at Purdue University..
