In this work are reported the Micro-Raman spectra of GexAsxSe1-2x (x = 0.05÷0.30). The Micro-Raman spectra consist of three main peaks located around ν = 193 cm-1, ν = 213 cm-1, and ν = 255 cm-1. The peaks around ν = 193 cm-1 and ν = 213 cm-1 could be attributed to the vibration of GeSe bonds. The presence of the Raman peak at ν = 255 cm-1 is due to the bond-stretching vibration of the disordered Se chains and rings. With the increase of the Ge concentration this peak shifts to a higher wavenumber due to the shortening of Se chains. The peak around ν = 300 cm-1 is characteristic to Ge-Ge vibration mode. The Ge concentration slightly changes the shape of Micro-Raman spectra, mainly its ratio of the intensity. |
