Phys. Rev. B 68, 085302 (2003) [5 pages]Electron-electron scattering in strong magnetic fields in quantum well systemsReceived 27 November 2002; published 7 August 2003 We have developed a theory of the electron-electron scattering in quantum well structures in the presence of a magnetic field. The scattering rate is obtained from the second-order expansion of the electron self-energy. We show that the rate oscillates as a function of the magnetic field, so that a strong suppression of the scattering can be expected in some ranges of high magnetic fields. Our theory also provides an easy tool for distinguishing this two-electron scattering process from other possible scattering mechanisms. © 2003 The American Physical Society URL:
