Abstract
The variation of the direct and indirect bandgap of compound GaxAl1-xA s systems with hydrostatic pressure and molar composition x has been c alculated at the high symmetry points GAMMA, X and L using the empiric al pseudopotential method coupled with the virtual-crystal approximati on. The bowing parameters have been studied in relation to molar compo sition and pressure.
