Optical parameters of the solid solution Hg1-xZnxTe as functions of x
are discussed and compared with experimental data wherever possible. S
emi-empirical and reliable relations are developed for the energy gap,
refractive index, effective mass, matrix element and absorption coeff
icient of this material. Experimental data on this coefficient are rep
orted here for the first time. (C) 1998 Published by Elsevier Science
