Morphological study of bulk sample averse to thin films for a quaternary glassy alloy system
Source abstract
Abstract
The structural properties of bulk as well as thin films of nanostructured Bi1Te15Se84-x Pbx (0 ≤ x ≤ 8) glassy alloys has been studied in this paper. Conventional melt quenching method is employed to prepare the samples of Bi1Te15Se84-x Pbx (0 ≤ x ≤ 8) alloys. Thin films with thickness of approximately 158nm of the obtained bulk compositions were deposited on dry cleaned glass substrates by thermal evaporation technique. The structural characterization was carried out using XRD and SEM. Energy dispersive X-ray spectroscopy (EDX) indicates that samples are nearly stoichiometric. X-ray diffraction patterns indicate that they are in the crystalline state. SEM study indicates the formation of snow flaky structures with agglomeration with the rise in lead content in the sample. Raman spectroscopy is used to study how changes in composition due to Pb doping affect lattice vibrations and electronphonon interactions.
