Extraordinary Electronic Switching of Thermal Transport
Abstract
The technical ability to dynamically switch the heat transport characteristics of solid state electronic and energy devices could help address mounting thermal management challenges. Existing approaches to tunable thermal transport in solids rely either on structural phase transformations or on modification of the scattering rates of energy carriers, typically either phonons or electrons. The switching ratios and speeds of existing approaches are insufficient to realize solid-state thermal switches, rheostats, regulators, or transistors that are as effective as their mechanical or fluid counterparts. This proposal identifies new routes to achieve rapid (from 10 Hz to GHz), large (>10x), and reversible electronic switching of heat transport in solids based on recent advances in physics and materials science, and outlies a research program intended to laythe groundwork for practical devices.
