Abstract

An increase in the reflection in the IR spectral range typical of a plasmon resonance in single crystals is observed in an InSb film formed by thermal evaporation in a vacuum on a CdS single crystal. Raman spectra demonstrate an approximately constant ratio between the amorphous and crystalline phases for InSb films on a CdS substrate, which is uncharacteristic of an InSb film on gallium–gadolinium garnet. The current–voltage characteristics of an InSb film on CdS are linear, as also those of an annealed sheet of InSb (core)–CdS (shell) quantum dots and, in addition, become sensitive to illumination.
