The results of studying the effect of an interface of crystallites on the energy spectrum of electrons in narrow-gap Bi 1 - x Sb x semiconductor bicrystals are reported (0.06 ≤ x ≤ 0.20). The structure of the reflection spectra for bicrystals with the inclined crystallite boundary and corresponding single crystals is analyzed. A number of features are revealed from comparison of the optical spectra of single crystals and bicrystals with the same parameters in wavelength ranges as high as 6 eV; these features are caused by the effect of the crystallites' interface on the energy spectrum of charge carriers. |
