The authors develop an efficient and accurate interpolation technique for the matrix elements of dielectric matrices in the entire q + G reciprocal space between material and substrate.The method makes possible quasiparticle energy calculations within the G\phantom\rule00exW approximation for arbitrarily mismatched interfaces, free of strain and symmetry constraints. This is extremely important for practical applications.
