Phase transition and Raman-active modes in TlInS sub(2)

Raman spectra of layered ternary thallium chalcogenide TlInS sub(2)were studied with the aid of 3D confocal Raman system over the temperature range 77-300K in the frequency region of 120-400 cm super(-1). The observed lines in the obtained Raman spectra were denconvoluted into Lorentzian peaks and t...

Zusammenfassung:Raman spectra of layered ternary thallium chalcogenide TlInS sub(2)were studied with the aid of 3D confocal Raman system over the temperature range 77-300K in the frequency region of 120-400 cm super(-1). The observed lines in the obtained Raman spectra were denconvoluted into Lorentzian peaks and temperature dependence of each peak's parameters (peak position and half width at half maximum) were obtained. An irregular behaviour of the temperature dependence of Loretzian parameters is reported. ([copy 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
