摘要
回顾了两个著名的广泛用于提取或参数化半导体和电介质材料光学常数的介电函数模型,即ForouhiBloomer和TaucLorentz模型的历史、各种改进、各自特点和应用.在揭示它们内在特点和比较运用在具体实例的基础上,拓展和预言了这两个模型更为深入的和更为广泛的应用.
This paper presents an overview of the history, modifications, characteristics, and applications of two well known dielectric function models ——the Forouhi-Bloomer model and the Tauc-Lorentz model——which have been widely used for the extraction and parameterization of optical constants in semiconductors and dielectrics. Based on analysis of their inherent characteristics and comparison via demonstrative examples, deeper and wider usage of the two models is predicted.
