ABSTRACT
Laser-driven hypervelocity impact experiments were used to study pressure-induced long-term effects on the crystal structure of undoped GaSb. X-ray diffraction and confocal micro-Raman spectra were collected on unshocked and shock-compressed samples, with corresponding pressures ranging between 8 and 23â GPa. GaSb retained bulk crystallinity at 8â GPa but showed localized site disordering, transformed into an amorphous state at 13â GPa, and stayed in that phase until 23â GPa.
