Comparison of dispersion models in the optical characterization of As-S chalcogenide thin films
Original language description
In this paper, the optical analysis of the As?S thin films prepared under different conditions is performed using three dispersion models for amorphous materials typically employed in practice. The Tauc?Lorentz (TL) model, Urbach?Cody?Lorentz (UCL) modeland our model based on the parameterization of the density of electronic states (PDOS model) are namely used to determine the optical parameters of these films. Within the structural model of the As?S films, the existence of the optical constants profiles and overlayers on to the upper boundaries of these films are included. Dispersion and structural models are employed within the analysis based on a combination of variable angle spectroscopic ellipsometry and transmission spectrophotometry in conjunction with multi-sample modification. It is demonstrated that the TL model is not suitable for the optical characterization of the As?S thin films because of the absence of the Urbach tail. Furthermore, it is shown that both the UCL and PDO
