概要
- 論文の詳細を見る
Optical absorption spectra of Ge crystals have been measured in the far-infraredregion at temperatures between 2 and 292 K. In the low energy region, structuresin the absorption spectra have been found around 100 and 200 cm ", which areassigned as being due to the two-phonon difference processes between TA andother phonons. The absorption spectrum due to the two-phonon difference processgives us information on the optical absorption process which is complementaryto the information obtained from the two-phonon summation spectrum.
