Query: Substrate screening approach for quasiparticle energies of
  two-dimensional interfaces with lattice mismatch   Two-dimensional (2D) materials are outstanding platforms for exotic physics
and emerging applications by forming interfaces. In order to efficiently take
into account the substrate screening in the quasiparticle energies of 2D
materials, several theoretical methods have been proposed previously, but only
applicable to interfaces of two systems' lattice constants with certain integer
proportion. In this work, we analytically showed the equivalence and
distinction among different approximate methods for substrate dielectric
matrices. We evaluated the accuracy of these methods, by applying them to
calculate quasi-particle energies of hexagonal boron nitride interface systems
(heterojunctions and bilayers), and compared with explicit interface
calculations. Most importantly, we developed an efficient and accurate
interpolation technique for dielectric matrices that made quasiparticle energy
calculations possible for arbitrarily mismatched interfaces, which is extremely
important for practical applications.
