摘要

由反斯托克斯光致发光驱动的半导体光学冷却，代表了一种创新的非接触冷却方法，与传统的基于热传导的方法有本质区别。最近的进展已经确定了具有强电子-声子相互作用的材料，如卤化物钙钛矿，作为通过声子辅助光吸收过程提高冷却效率的有希望的候选者。本展望探讨了电子-声子相互作用在决定光学冷却性能中的关键作用，并强调了半导体量子点的最新发展，为这一新兴技术的未来提供了见解。

Cooling Semiconductors with Light: The Role of Electron–Phonon Interactions and Nanostructures

Optical cooling in semiconductors, driven by anti-Stokes photoluminescence, represents an innovative approach to noncontact cooling that fundamentally differs from conventional heat conduction-based methods. Recent advancements have identified materials with strong electron–phonon interactions, such as halide perovskites, as promising candidates for enhancing cooling efficiency through phonon-assisted photoabsorption processes. This Perspective explores the critical role of electron–phonon interactions in determining optical cooling performance and highlights the recent developments in semiconductor quantum dots, offering insights into the future of this emerging technology.
