Spin-Flip Raman Scattering in Cadmium Sulfide.
Abstract
The 4880A line of an Argon laser was used to study the spin-flip Raman scattering in CdS at liquid helium temperature. The detection system utilized a Bausch and Lomb two meter spectrometer. The first high resolution photograph of Stokes spin-flip scattering in CdS was observed. The results with SdS indicate the feasibility of using this high resolution system in experiments with small g-factor materials such as GaAs, CdTe, and CdSe. The g-factor calculations for CdS give 1.54 at 83 KG, 1.62 at 91 KG and 1.74 at 96 KG. These results, in contrast with previous experimental data, give a smaller g-factor that varies with magnetic field. A possible explanation is that the spin-flip transition occurred in a donor level rather than the conduction band. The Stokes line was found to have a very narrow linewidth .33A, and its intensity was several orders of magnitude higher than the LO and TO phonons. (Author)
