Tunable Resonant Columbic Heat Transport between Moire Superstructures
Abstract
This Supplemental Support for Research Trainees (SSRT) will be used to support Ms. Devika Mehta to pursue an experiment as part of h,er PhD dissertation and an ONR MURI project on Extraordinary Electronic Switching of Thermal Transport. The objective of this experi,ment is to demonstrate the concept of electrostatic tuning of interfacial Coulombic heat transport between two moir structures sepa,rated by few-layer hexagonal boron nitride (hBN). This research is motivated by a theoretical proposal that the Coulombic heat trans,port can be rapidly switched on and off with gate electric fields to control the band filling of two adjacent two-level systems, whi,ch will be realized by the flat electron bands of moir superstructures. This large and rapid thermal switching capability can enabl,e energy-efficient electro/magneto-caloric refrigeration and phase change memories. Devika will employ a Wheatstone bridge setup to,measure the interface thermal conductance when Coulombic heat transport is set at the resonant condition. Approved for Public Releas,e.
