- Abstract
This study is focused on investigating the atomic dynamics and vibrational properties of thin layers of cadmium selenide with thickness ranging from 200–500 nm. The studies were carried out using Raman spectroscopy at room temperature. Raman spectra were obtained in the frequency range ν = 100-800 cm-1 . Two vibration modes were observed within the specified frequency range. It has been established that these vibration modes correspond to vibrations of Cd–Se covalent bonds. The frequency of these vibrational modes was observed to increase as the thickness of CdSe thin films increased, which was attributed to the formation of a thickness-dependent phase.
