Counts as:

Experimental Course Offered: Fall 2007

Requisites:
Prerequisites: MA 266 and MA 265 or MA 262 Concurrent Prerequisites: ECE 305

Requisites by Topic:
Prerequisites: Familiarity with matrix algebra, MATLAB, Elementary differential equations. Concurrent Prerequisites: Basic semiconductor device physics.

Catalog Description:
The development of "nanotechnology" has made it possible to engineer materials and devices on a length scale as small as several nanometers (atomic distances are ~ 0.1 nm). The properties of such "nanostructures" cannot be described in terms of macroscopic parameters like mobility or diffusion coefficient and a microscopic or atomistic viewpoint is called for. The purpose of this course is to convey the conceptual framework that underlies this microscopic viewpoint using examples related to the emerging field of nanoelectronics.

Course Objectives:
To convey the basic concepts of nanoelectronics to electrical engineering students with no background in quantum mechanics and statistical mechanics.
