Pressure-dependent magneto-optic measurements in strained-layer superlattices at low temperatures
Conference

OSTI ID:6308561
Magneto-optic studies on InGaAs/GaAs and GaAs/GaPAs strained-layer superlattices are used to determine the in-plane light-hole valence-band effective masses. Also, hydrostatic pressure-dependent magneto-optic studies have been performed on these samples for magnetic fields up to 65 kG and pressures to 4 kbar in the temperature range of 1.6 to 4 K. The experimental pressure coefficients of the band-gap energy and the effective mass in the InGaAs/GaAs SLS structures were determined.
