Abstract

In the framework of quantum perturbation theory the self-consistent method of calculation of electron scattering rates in nanowires with the one-dimensional electron gas in the quantum limit is worked out. The developed method allows both the collisional broadening and the quantum correlations between scattering events to be taken into account. It is an alternativeper seto the Fock approximation for the self-energy approach based on Green’s function formalism. However this approach is free of mathematical difficulties typical to the Fock approximation. Moreover, the developed method is simpler than the Fock approximation from the computational point of view. Using the approximation of stable one-particle quantum states it is proved that the electron scattering processes determine the dependence of electron energy versus its wave vector.

Highlights

  • In the framework of quantum perturbation theory the self-consistent method of calculation of electron scattering rates in nanowires with the one-dimensional electron gas in the quantum limit is worked out

  • Let us postulate Eq (2) using the scattering rates derived taking into account the high-order quantum effects. To do it we use the results of Refs. [5,6,7,8]. In these studies the scattering rates in GaAs quantum wires have been calculated taking into consideration the collisional broadening of the initial electron quantum states

  • The expressions for calculation of the rates of elastic Wel and inelastic We/a electron scattering derived in the framework of the approximation of stable one-particle quantum states in the one-dimensional electron gas in the quantum limit and thermodynamic equilibrium are presented in the following explicit form: WielðEÞ 1⁄4 CielqðE; DEðEÞÞ Miel=fðk0ðDEðEÞ=2ÞÞ2þ Mei l=bðk0ðE þ DEðEÞ=2ÞÞ2!ð1 À fFðEÞÞ; ð9Þ
