Аннотация

Structural and piezoelectric properties of boron-antimonide (BSb) under high pressure up to 60 GPa were investigated using the pseudopotential plane wave method in the framework of the density functional theory within the local density approximation for the exchange-correlation functional. Both direct and converse piezoelectric coefficients were obtained using the density functional perturbation theory. Both direct and converse piezoelectric coefficients decrease gradually with pressure.
