Room-temperature experimental (open circles) and calculated (solid curves: total fits, and dashed curves: Lorentzian fits, and dotted curves: the CPPM theory fits) Raman spectra of N–In codoped -type ZnO thin films. Photoluminescence backgrounds have been subtracted from the Raman spectra.
(a) Intensity ratios (filled squares) of the InN (high) mode to the ZnO CPPM as a function of Hall density . (b) Depletion layer depth (filled circles) under different Hall densities . The dashed line is the penetration depth of the UV laser in ZnO.
(a) Raman shift of the ZnO CPPM vs Hall density . (b) FWHM of the ZnO CPPM vs Hall mobility . (c) Optical hole densities vs Hall density . The solid line represents . (d) Optical mobilities (solid curve) and (dashed curve) compared with (filled squares).
