Bandstructure calculations for holes in GaAs and simulations of dc conductance in electron quantum point contacts
… measurements. We present simulations of the 0.7 feature known from QPC measurements. We were looking at three scenarios in which a spontaneous spin gap opens and is responsible for the occurrence of the 0.7 feature. The spin gap depends linearly on the gate voltage. The scenarios differ in the …
