Effect of Intersubband Impurity Scattering on the Anderson Localization in Two Dimensional Electron Systems

Lithium Intercalation in Bilayer Graphene Devices

“…In the electron-hole puddle regime near charge neutrality (grey solid line), two charge carrier types contribute to the QI eect. As this regime is not of primary interest to this work, we only note that if a two-band model was to apply in this case, an enhancement of the eect could be expected, 83 which would be in line with our observation.…”

Anomalous dephasing of two-dimensional electrons in an AlGaAs/GaAs parabolic quantum well structure

“…WL in a two-dimensional system with two occupied subbands has been theoretically studied [14,15]. It was shown that if short-range scattering is dominant and intersubband scattering is strong, the subbands couple and the electrons behave as if they occupy a single subband characterized by an average kinetic parameter.…”

Effect of intersubband scattering on weak localization in two-dimensional systems

“…One can see, the conductivity correction ∆σ 2 is independent of magnetic field, because the current vertices in (10), J α (ρ 2 , ρ 1 ), contain the phase factor which is complex conjugated…”

“…9 The intersubband scattering was considered only in the diffusion regime. [10][11][12][13][14] The aim of the present paper is to develop the theory of weak localization in quasi-2D systems for the whole range of classically low magnetic fields. It is the theory that is necessary for quantitative determining of kinetic parameters of structures by comparison with experimental data.…”
