Optical properties of InxGa1-xN alloy and In0.5Ga0.5N/GaN multi
quantum wells have been investigated in the region of far infrared. Far-IR
reflectivity spectra of In0.5Ga0.5N/GaN multi quantum wells on GaAs
substrate have been obtained by oblique incidence p- and s-polarization light
using effective medium approximation. The spectra and the dielectric
functions response give a good informa...
