Fundamentals of Current Flow


Credit Hours:


Learning Objective:

This course is part of a Purdue initiative that aims to complement the expertise that students develop with the breadth at the edges needed to work effectively in today's multidisciplinary environment.


This is a one credit hour course, not three credit hours. Class duration: Aug 20, 2018 - Sep 23, 2018.The traditional description of electronic motion through a solid is based on diffusive transport, which means that the electron takes a random walk from the source to the drain of a transistor, for example. However, modern nanoelectronic devices often have channel lengths comparable to a mean free path so that electrons travel ballistically, or like a bullet. This course provides a unified conceptual framework for ballistic and diffusive transport of both electrons and phonons, that is very different from what is taught in standard courses, but indispensable to understanding nanoelectronic devices.

Topics Covered:

Ballistic and diffusive conductance, density of states, number of modes, conductivity, thermoelectric coefficients and thermal conductivity


Undergraduate degree in engineering or the physical sciences , specifically differential equations, and linear algebra.

Applied / Theory:






Three exams, no final
