Dielectric effects in the optically stimulated electron spin resonance in silicon

Abstract
The appearance of the photoinduced ESR lines is directly responsible for the dielectric effect caused by a change in spin‐dependent photoconductivity at resonance point. This appearance mechanism proposed in the optically stimulated ESR method is quite different from that of an ordinary ESR absorption line based on the paramagnetic absorption loss. A simple calculation to justify this model is made and typical features of the photoinduced ESR lines are explained in connection with the appearance mechanism.
