Abstract
A computational study of elastic and piezoelectric properties of crystalline ZnxCd1-xS obtained from a pseudopotential approach is presented. We report composition-dependent values of elastic constants, bulk modulus, shear modulus, Young's modulus, Poisson ratio, piezoelectric stress constant, piezoelectric strain constant and electromechanical coupling constant. Our findings show a reasonable accord with data in the literature where available, and allow predictions where they are not. Our findings are expected to provide useful information for understanding the elastic and piezoelectric properties of ZnxCd1-xS and for applications in optoelectronics.
