Abstract

The Raman spectra of pentanary GaInAsSbP alloys are reported for the first time. Measurements were performed at room temperature on epilayers which were grown using liquid phase epitaxy outside of the miscibility gap and nominally lattice matched to (1 0 0) InAs and GaSb. The dominant phonon peaks in the spectra are identified and attributed to InSb-, InP-, GaAs- and (GaSb+InAs)-like phonons, along with disorder-activated phonons. No GaP-like phonons were observed. Further peaks were also attributed to disorder-activated optical and longitudinal acoustic phonons, associated with alloy disorder effects.
