Abstract

The polarization field of barrier-doped In_0.06Ga _0.94N/Al_0.1In_0.02Ga_0.88N multiple quantum well in the p-i-n diode structures was measured by electroreflectance. The bias dependent electroreflectance spectra displayed an intensity minimum and an 180° phase change at the flat-band voltage. The polarization field in QW was calculated by the self-consistence calculations of Poisson equation. It is found that the polarization field is 0.21 M V/cm, and independent of barrier doping.
