Solid-state thermal control devices

Published by lahde on

An extensive review of thermal management with thermal control devices based on solid-state physics phenomena has been published in collaboration with colleagues from the Universities of Twente (Dr. Miguel Muñoz Rojo and Timm Swoboda) and Stanford (Dr. Ananth Saran Yalamarthy). A review article published in the journal Advanced electronic materials (published by Wiley) presents the first of two parts of a review of thermal control devices.

Over the past decade, solid‐state thermal control devices have emerged as potential candidates for enhanced thermal management and storage. They distinguish themselves from traditional passive thermal management devices in that their thermal properties have sharp, nonlinear dependencies on direction and operating temperature, and can lead to more efficient circuits and energy conversion systems than what is possible today. They also distinguish themselves from traditional active thermal management devices (e.g., fans) in that they have no moving parts and are compact and reliable. In this article, the recent progress in the four broad categories of solid‐state thermal control devices that are under active research is reviewed: diodes, switches, regulators, and transistors. For each class of device, the operation principle, material choices, as well as metrics to compare and contrast performance are discussed. New architectures that are explored theoretically, but not experimentally demonstrated, are also discussed.
