Paper Abstract

The magnetic circular dichroic (MCD) spectra for 160- and 290-angstroms thick films of CuCl were measured around the Z3 exciton region up to 6 tesla at 10 K. These thicknesses are in the region where the long wave approximation is valid. These MCD spectra of the quantized states of translational motion of the Z3 excitons were explained well by Zeeman splitting. The g-values of these quantized states in the CuCl thin films were obtained by fitting these spectra to an approximation model, and the g-values obtained are identical to that of a 1700-angstroms thick sample. No change of the g-values of each quantized state was observed. These results indicate that this quantum size effect has no contribution to the relative motion of electron and hole in excitons in these film thicknesses.
