Fundamental optical properties of heavily-boron-doped silicon

Abstract
Infrared-reflectivity data for B-ion-implanted and laser-annealed Si crystals are reported. In particular, the free-carrier response is analyzed by using the Drude relationships; new information both on the effective mass and scattering time is obtained in the presence of controlled amounts of disorder and a variable density of free holes. The free-carrier concentration is measured by means of the analysis of the x-ray intensity profiles obtained by double-crystal diffraction.
