Spin gap in the 2D electron system of GaAs/AlGaAs single heterojunctions in weak magnetic fields
V. S. Khrapai, A. A. Shashkin, E. L. Shangina +4
We study the interaction-enhanced spin gaps in the two-dimensional electron gas confined in GaAs/AlGaAs single heterojunctions subjected to weak magnetic fields. The values are obt…

Direct measurements of the spin and the cyclotron gaps in a 2D electron system in silicon
V. S. Khrapai, A. A. Shashkin, V. T. Dolgopolov
Using magnetocapacitance data in tilted magnetic fields, we directly determine the chemical potential jump in a strongly correlated two-dimensional electron system in silicon when…

Screening and inplane magnetoresistance of anisotropic two-dimensional gas
V. S. Khrapai
In order to split the influence of the orbital and spin effects on the inplane magnetoresistance of a quasi two-dimensional gas we derive its linear response function and dielectri…
