Several current topics of research includes: (1) transport in engineered moiré superlattices at vdW interfaces with an adjustable length scale controlled by twist angles between the layers; (2) Probing thermal transport in junctions of atomic dimensions is crucial for understanding the ultimate quantum limits of energy transport. These limits have been explored in a variety of microdevices ( 14 – 18 ), where it has been shown that, irrespective of the nature of the carriers (phonons, photons, or electrons), heat is ultimately Modern semiconductor devices scale down to the nanometer range. Heat dissipation becomes a critical issue in the chip design. From a different perspective, energy conservation has attracted much of attention from researchers. The essence of heat dissipation and energy conservation is the heat transport. Thermal properties of semiconductors have been under intense investigation in recent experimental study of thermal transport in these systems constitutes a formidable challenge and has remained elusive to date, in spite of its fun-damental interest (13).

Thermal transport for probing quantum materials

The thermal conductivity is measured using optical heating as well as electrical heating, yielding 37 +/- 3W m(-1) K-1 for the fast (ladder) direction and 2.5 +/- 0.5W m K-1 for the slow direction, respectively. We report thermal conductivity and Hall coefficients of both materials measured down to 0.3K. The observed thermal conductivity oscillations with novel angle dependence in α-RuCl3 strongly suggest a quantum oscillation mechanism that arises from the charge-neutral Fermi surface.

Introduction. In conventional electronic devices such as field-effect transistors (FETs) or diodes, the size of the device is usually quite large, so that the wave nature of the electron or its discrete charge do not influence the behavior of the device. Furthermore, all individual "Quantum size effects provide an excellent opportunity for engineering materials with novel thermal properties suitable for energy conservation and conversion technologies such as State-of-the-art computational and experimental nanoscale energy transport methods are reviewed, and a broad range of materials system topics are considered, from interfaces and molecular junctions to nanostructured bulk materials.
