Abstract :
Semi-insulating Fe-doped InP samples have been investigated by optical reflectance measurements before and after fast neutron irradiations with fluences ranged from 7.2/spl times/10/sup 12/ to 3.8/spl times/10/sup 15/ neutron/cm/sup 2/. From the spectral dependence of the reflectance in the photon energy range between 1.5-6.0 eV the determination of the optical constants (real refractive index, extinction coefficient, real and imaginary parts of the dielectric function, respectively, and absorption coefficient) has been performed using the Kramers-Kronig dispersion analysis technique.
