Intraconduction Band Magneto‐Optical Study of InSb under Hydrostatic Pressure

Abstract
The cyclotron resonance and electron spin resonance of n‐InSb under hydrostatic pressure up to 1 GPa are investigated using photoconductivity techniques. All the transitions observed are fitted using a modified Pidgeon‐Brown model with a set of band parameters recently proposed by Goodwin and Seiler and a change of the band gap of dEg/dP = (0.140 ± 0.004) meV/MPa, a value in good agreement with experimental results.
