Abstract:

Observations were made of the exciton spectra in wurtzite cadmium selenide. The identification and subsequent interpretation was facilitated by measurements of the magneto-optical effects of the spectra. A qualitative understanding of the spectra is obtained from a review of the allowed band symmetries at K equals 0,0,0 in crystals of C subscript 6V superscript 4 symmetry. The exciton symmetries and selection rules are obtained group theoretically. A quantitative comparison with an anistropic exciton mass theory, which will be outlined, permits evaluation of the electron and hole mass and g value parameters. Author
