Indirect band-gap transitions in GaP shocked along the [100], [110], and [111] axes


Shock compression experiments were performed to investigate optical changes in GaP under uniaxial strain. Low-temperature transmission spectra of sulphur-doped GaP samples were obtained at longitudinal stresses up to 5 GPa for shock wave loading along the 100 , 111 , and 110 orientations. At low uniaxial strains, changes in the band-gap absorption edge were… (More)
