Abstract

We investigate optical and piezoelectric properties of the orthorhombic PdS 2 under symmetrical biaxial tensile strains with various magnitudes. The ab initio simulation results found that the peaks of the refractive index, extinction coefficient, absorption coefficient, and reflectivity of the orth...
