Abstract

Electron-electron scattering processes in a quantum well in a quantizing magnetic field are considered. A matrix of electron-electron scattering rates containing all types of transitions between Landau levels within a single subband is calculated. This matrix is analyzed, and the relative magnitude of transition rates of different types is determined.
