摘要：
This paper shows that the absorption spectrum in the 1.6-15-mu m region in germanium crystals, which results from plastic strain, is mainly determined by two parameters: the initial carrier concentration and the degree of plastic strain. The free-carrier absorption is unambiguously associated with the electric parameters only when the strain is not too great (<6%). (C) 2007 Optical Society of America.
