Observation of resonance radiation in the region of the continuous spectrum of semiconductors
Dvornikov D.P., Salmanov V.M., Yaroshetskii I.D.
Observation is reported, with indium and gallium monoselenides (InSe and GaSe) as examples, of resonance radiation due to transitions from states located in the interior of the conduction band and the valence bands and situated at distances commensurate with the width of the semiconductor forbidden band. The concept of a hyperbolic exciton is suggested as a possible explanation of the nature of the observed radiation.
