摘要
We report the values of the absorption coefficient of 4H, 6H and 3C SiC at room temperature, in the range 3900-2968 Angstrom. By using the known shift in the bandgap with temperature, we also present estimates of the absorption coefficient of 4H, 6H and 3C SIC at 2 K. A table is given for penetration depths at 300 and 2 K for seven common lasers used to pump SIC in this region. (C) 1999 Elsevier Science S.A. All rights reserved.
