ECE 606: Principles of Semiconductor Devices
12 Nov 2008  Courses  Contributor(s): Muhammad A. Alam
In the last 50 years, solid state devices like transistors have evolved from an interesting laboratory experiment to a technology with applications in all aspects of modern life. Making transistors is a complex process that requires unprecedented collaboration among material scientists, solid state physicists, chemists, numerical analysts, and software professionals. And yet, as you will see in part 1 of this course (first 5 weeks), that the basics of current flow though solid state …

2008 NCN@Purdue Summer School: Electronics from the Bottom Up
26 Aug 2008  Workshops  Contributor(s): Muhammad A. Alam, Supriyo Datta, Mark Lundstrom
Electronics from the Bottom Up is designed to promote the bottomup perspective by beginning at the nanoscale, and working up to the micro and macroscale of devices and systems. For electronic devices, this means first understanding the smallest electronic device – a single molecule with two contacts. For carrier transport, it means beginning at the nanoscale where ballistic transport, atomistic effects, and stochastic effects dominate. For MOSFETs, it means beginning with the “ultimate” MOSFET. Electronics from the Bottom Up does not mean ab initio numerical simulations – it means beginning with concepts and approaches that are both simple and sound at the nanoscale rather than extrapolated from the microscale.
