Abstract:
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.

Semiconductors
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...
Fermi Level Dynamics
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...
