Monte Carlo quantum simulation of a resonant tunneling heterostructure for thermionic cooling

We investigate the operation of a resonant tunneling diode acting as a refrigerator based on the thermionic effect. The electrothermal transport phenomena are tackled by solving the Wigner–Boltzmann transport equation coupled to the heat equation. The simulation results demonstrate that this device can reach relatively high cooling power. However, in the specific implementation analyzed, the maximum reduction in lattice temperature is significantly constrained by the thermal conductivity of the materials used. Finally, we discuss potential approaches to optimize the device’s performance.

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
