Abstract

We study the strong effect of a small concentration (1 part per 1000) of randomly distributed N-resonant scatterers on the quantized Landau level states of a GaAs quantum well. Our magneto-tunneling spectroscopy measurements allow us to probe the resonant and non-resonant component of the N-related scattering potential.
