概要
- 論文の詳細を見る
Hydrostatic pressure shifts of valence and core exciton peaks in Kl are measuredwith a modulation method at about 120 K. The pressure coefficients are deter-mined to be, in units of 10-' meV/bar, 17.0 and 4.7 for the valence excitons at5.73 and 7.22 eV, and 18.8, 1"/.0 and - 38.7 for the core excitons at 19.95, 20.20and 21.05 eV, respectively. The pressure shifts of the lowest exciton at 5.73 eVand the corc excitons are discussed with a simple model of localized transitions.Experimental results for the lowest exciton and the core excitons at 19.95 and20.20 eV are explained well in this model, but the shift of the core exciton at21.05 eV does not agree with the theoretical expectation. The exciton-phononinteraction term contributing to thermal shifts of the excitons is deduced fromthe present pressure coefficients.
