Simulation and characterisation of opto-thermionic cooling devices

点击翻译按钮获取中文摘要

Opto-thermionic devices combine thermionic emission and laser cooling to achieve the maximum cooling power and highest thermal efficiency. These devices are ultra small, very reliable and fully integrable. Many important problems need to be solved to improve the performance of this new class of solid-state cooling devices. One is to understand and manipulate the electron-hole radiative recombination and minimize the Auger process in reduced dimensionality devices such as quantum wells. Researchers at Wollongong and Lund will collaborate on theoretical analysis, computer simulation and electrical/optical measurements to solve this problem.
