Inas dielectric function
WebMar 13, 2012 · Here, we predict the frequency dependent dielectric functions for nine non-nitride wurtzite phase III-V semiconductors (AlP, AlAs, AlSb, GaP, GaAs, GaSb, InP, InAs, and InSb).Their complex dielectric functions are calculated in the dipole approximation for light polarized parallel and perpendicular to the c axis of the crystal. WebAug 17, 1998 · The imaginary part of the dielectric function [ε 2 (ω)] is derived first from the joint density‐of‐states functions at energies of various critical points (CPs) in the Brillouin zone; then its real part [ε 1 (ω)] is obtained analytically using the Kramers–Kronig relation.
