This video is part of the nanoHUB-U course "Thermal Energy at the Nanoscale" (http://nanohub.org/courses/te)

Thermal Energy at the Nanoscale, taught by Tim Fisher, is a five-week online course that develops a unified framework for understanding essential physics of nanoscale thermal energy and its important applications, trends, and directions. The course is designed to present this in a way that is accessible with only a very basic knowledge of heat transfer. The course will present an understanding of the fundamental elements of solid-state physics relevant to thermal transport, develop skills to derive continuum physical properties from sub-continuum principles, and apply statistical and physical principles to describe thermal energy transport in modern small-scale materials and devices.
