- 論文の詳細を見る
Piezoreflectivity spectra of Kl were measured and energy shifts due to the cubic,tetragonal and trigonal deforntations were obtained on the lowest energy exciton andthe step which has been identified with the onset of a band to band transition. Energyshifts of the exciton were found similar to those of the step in the case of the uniaxialdeformations. The similarity was reduced to the similarity of the electronic state,because of the large spin-orbit splitting of the 5p state of an I - ion. Difference in shiftenergy of the exciton and the step in the case of the cubic deformation was accountedfor by changes of the effective mass and the high frequency dielectric constant. In addition, energy shifts determined directly from the piezorefleclivity were shown to bethe same as those determined from the deformation induced changes of dielectric conslants.
