Abstract

The physical properties of antimony selenide (Sb₂Se₃) are highly anisotropic. Angle-resolved polarised Raman spectroscopy was employed to characterise oriented crystals and used in conjunction with group theory structural analysis to assign vibrational symmetries to the peaks observed in the Raman spectra. The phonon energies were corroboratedviadensity functional theory (DFT) calculations. Furthermore, a straightforward method is proposed to verify the desirable (001) plane orientation of film growth for device applicationsviaminimisation of the 155 cm⁻¹peak in the Raman spectrum.
