Abstract

Abstract The temperature dependence of the optical constants of materials (refractive index, absorption and extinction coefficients, and dielectric function) can be determined with spectroscopic ellipsometry over a broad range of temperatures and photon energies or wavelengths. Such results have practical value, for example for applications of optical materials at cryogenic or elevated temperatures. The temperature dependence of optical gaps and their broadenings also provides insight into the scattering of electrons and holes with other quasiparticles, such as phonons or magnons. This review presents a detailed discussion of the experimental considerations for temperature-dependent ellipsometry and selected results for insulators, semiconductors, and metals in the infrared to ultraviolet spectral regions.

光谱椭偏仪从10到700 K

材料的光学常数(折射率、吸收和消光系数以及介电函数)的温度依赖性可以用光谱椭偏法在很宽的温度和光子能量或波长范围内确定。这样的结果具有实用价值，例如在低温或高温下光学材料的应用。光隙及其加宽的温度依赖性也为电子和空穴与其他准粒子(如声子或磁振子)的散射提供了洞见。本文详细讨论了温度相关椭偏仪的实验考虑因素，以及在红外到紫外光谱区域对绝缘体、半导体和金属的选择结果。
