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.

光热电子器件将热电子发射和激光冷却相结合，以实现最大的冷却功率和最高的热效率。这些设备超小、非常可靠且完全可集成。为了提高这种新型固态冷却设备的性能，需要解决许多重要问题。一是理解和操纵电子空穴辐射复合，并最大限度地减少量子阱等降维器件中的俄歇过程。卧龙岗和隆德的研究人员将在理论分析、计算机模拟和电/光测量方面进行合作，以解决这一问题。
