| Abstract | This paper discusses the optical absorption in polarized light of single crystals of CuGe0, in the 2000-30 000-cm-' (0.25-3.7-eV) region. The absorption edge in the UV part of the spectrum (3.1 eV for Ellc and 3.4 eV for Ellb) is determined, and an absorption band with a width of 0.5 eV is found at the boundary between the red and IR regions. The features on the absorption curve in the red region are compared with the results of a band-structure calculation carried out earlier by other authors. O 1996 American Institute of Physics.
