چکیده انگلیسی
Antimonselite (Sb2Se3) bulk material has been prepared by mechanical alloying through ball milling of the elemental precursors antimony (Sb) and selenium (Se) in place of conventional solid state synthesis. X-ray diffraction (XRD), Raman spectroscopy studies and Energy dispersive spectroscopy (EDS) studies confirm the formation of polycrystalline Sb2Se3 along with elemental Sb. The as-milled bulk material was used as source to deposit Sb2Se3 thin films by e-beam deposition. Thin films have been grown at a substrate temperature of â¼373â¯K with an optimal electron beam current (Ib) of â¼30â¯mA at fixed voltage of â¼5â¯kV. The films were studied using XRD and Raman spectroscopy for the structural and phase analyses. Scanning electron microscopy (SEM) studies and energy dispersive spectroscopy (EDS) measurements revealed the formation of near stoichiometric thin films with smooth and uniform surface. Rutherford backscattered spectrometry (RBS) and proton induced X-ray emission spectroscopy (PIXE) tools were employed to confirm the chemical composition of as-grown Sb2Se3 thin films. Optical transmission spectrum showed a very sharp transition near the fundamental absorption edge â¼1.26â¯eV. The films exhibited an average absorption coefficient values exceedingâ¯> 104 cmâ1 in the visible region making it a promising material for solar absorber in thin film solar cell.
