Raman scattering has contributed to the understanding of semiconductor materials at a fundamental level and has also proved powerful in the characterization of semiconductors, their alloys and heterostructures. This brief review will indicate some of the ways in which Raman spectroscopy has been applied in the study of II-VI semiconductors, with special attention to recent examples relevant to the application of ZnSe-based materials in optoelectronics. In particular, studies of electron spin-flip Raman scattering in p-type ZnSe will be discussed which show the presence of two distinct donor centres in highly doped p-type ZnSe:N; the two donors can be distinguished in spin-flip Raman scattering experiments by their different g-values. The resonance behaviour of the two Raman signals confirms that they are associated with two different donor centres and reveals a correlation between the localisation energy of an exciton at the neutral donor centre and the binding energy of the electron to the donor ion. Directions for future experiments will be indicated.
