Anomalous Urbach tail in GaAs.
The Urbach tail in crystalline GaAs and Si due to thermal vibration is evaluated in the temperature range 0—810 K. Recent experiments suggest that there is no thermally induced Urbach tail in undoped GaAs. This is most unexpected since thermally induced tails at the absorption edge having the Urbach form and widths Eo(T) linear in T are observed in a wide range of crystalline and amorphous semi...
متن کاملOptical absorption parameters of amorphous carbon films from Forouhi-Bloomer and Tauc-Lorentz models: a comparative study
Parametrization models of optical constants, namely Tauc-Lorentz (TL), Forouhi-Bloomer (FB) and modified FB models, were applied to the interband absorption of amorphous carbon films. The optical constants were determined by means of transmittance and reflectance measurements in the visible range. The studied films were prepared by rf sputtering and characterized for their chemical properties. ...
متن کاملEffect of the Sulfur Concentration on the Optical Band Gap Energy and Urbach Tail of Spray-Deposited ZnS Films
Zinc sulfide (ZnS) films were deposited through a simple and low cost spray pyrolytic technique using mixed aqueous solutions of zinc nitrate and thiourea. The structural and optical properties of these films were investigated as a function of initial (Zn:S) molar ratio in the precursor solution, which varied between (1:1) and (1:3). X-ray diffraction (XRD) analysis revealed that wurtzite...
متن کاملFirst-principles calculations of the Urbach tail in the optical absorption spectra of silica glass.
We present density-functional theory calculations of the optical absorption spectra of silica glass for temperatures up to 2400 K. The calculated spectra exhibit exponential tails near the fundamental absorption edge that follow the Urbach rule in good agreement with experiments. We discuss the accuracy of our results by comparing to hybrid exchange correlation functionals. We show that the Urb...
متن کاملOptical properties and local bonding configurations of hydrogenated amorphous silicon nitride thin films
We report on the optical properties and local bonding configurations of both as-deposited and postannealed hydrogenated amorphous silicon nitride a-SiNx :H thin films grown on crystalline Si substrates with x approximately 1.2±0.1. Ultraviolet optical reflection and infrared IR absorption measurements were applied to characterize the films. A method simply based on optical reflection spectra is...
