Abstract

Samples from the Bi2(Se1−xTex)3 system, where x = 0, 50 % and 100 mol.% have been studied with respect to their structure and properties. XRD analysis revealed a polycrystalline single phase structure of the materials. The crystallization temperature (Tc,p) and the melting temperature Tm of the samples have been determined from differential scanning calorimetric (DSC) and thermogravimetric (TGA) analyses. Thin films have been deposited from the respective bulk alloys by means of the vacuum thermal evaporation method. The thicknesses of the films, the optical constants and the optical band gap have been derived from transmission and reflection spectra.
