Weak localization in indium nitride films

We have studied the weak localization (WL) effects in the electron accumulation layer on InN surface. Both the spin-orbit relaxation time τso and the electron-phonon scattering time τe-ph have been extracted from the WL analysis. We have observed that 1/τso increase with disorder and τe-ph exhibits a tendency to change gradually from the characteristic dependence 1/τe-ph ∝ T3 in the pure case to the form of T2l-1 with increasing disorder.
