Thermal transport: Cool electronics

Although heat removal in electronics at room temperature is typically governed by a hierarchy of conduction and convection phenomena, heat dissipation in cryogenic electronics can face a fundamental limit analogous to that of black-body emission of electromagnetic radiation.

Summary:Although heat removal in electronics at room temperature is typically governed by a hierarchy of conduction and convection phenomena, heat dissipation in cryogenic electronics can face a fundamental limit analogous to that of black-body emission of electromagnetic radiation. A study by Austin Minnich and co-authors provides an elegant demonstration of this limit of heat transfer for indium phosphate high-electron-mobility transistors.
