Optical Properties of Dilute Bismides

Abstract

Dilute bismides have attracted great attention due to their promising optoelectronic applications, of which the optical properties are a major theme experimental studies. In this chapter, recent progress in the optical spectroscopic study of several representative III-V group dilute bismides is overviewed, with a focus on the photoluminescence (PL) and photoreflectance (PR) results especially by improved spectroscopic methods. Typical data from dilute bismides by other spectroscopic techniques of, e.g., Raman scattering, absorption and refractive index, are also briefly reviewed.
