Abstract
By determining the parameters of the parametric model (PM) for selected Al compositions x of In1-xAlxSb, we provide the information needed to accurately calculate the room-temperature dielectric functions ε = ε1 + iε2 of these alloys from 1.5 to 6.0 eV as a continuous function of x over the entire composition range 0 ≤ x ≤ 1. Our parameters are determined from data obtained by spectroscopic ellipsometry for Al compositions x = 0.00, 0.142, 0.341, 0.539, 0.754, and 1.00. The PM dielectric functions are found to be in excellent agreement with the data. These results will be useful in many aspects of research and technology.
