Abstract:

New high-resolution low-temperature 7.5K farinfrared data on intrinsic germanium and silicon are presented. The findings further substantiate the naturally anticipated similarities in band patterns of the vibrational spectra of diamond type crystals. The low temperature spectra of germanium and silicon show clearly resolved splits in their principal absorption bands analogous to the intriguing doublet in the ca. 2000cm band in diamond. A possible explanation is indicated. The room temperature far-infrared refractive index of both germanium and silicon and the 7.5K refractive index of germanium have been measured by means of interference fringes. Author
