Abstract
The plasma reflection spectra of the doped bismuth and bismuth-antimony all oyed crystals were studied experimentally at liquid-nitrogen temperature wi thin a range of 30-600 cm(-1). Specificities in the optical functions of th e samples are revealed within the infrared range that lies on the low-frequ ency side of the plasma edge and coincides with the optical-phonon frequenc ies in bismuth. When the plasma frequency is approached, the character of t he interaction of radiation with anisotropic electron-hole plasma changes c onsiderably. (C) 2001 MAIK "Nauka/ Interperiodica".
