Starting with the simplest semiclassical approaches and ending with the description of
complex fully quantum-mechanical methods for quantum transport analysis of state-of-the …

Besides the usual conductance plateaus at multiples of 2 e 2/h, quantum point contacts
typically show an extra plateau at∼ 0.7 (2 e 2/h), believed to arise from electron-electron …

The integer quantised conductance of one-dimensional electron systems is a well-
understood effect of quantum confinement. A number of fractionally quantised plateaus are …

There is controversy as to whether a one-dimensional (1D) electron gas can spin polarize in
the absence of a magnetic field. Together with a simple model, we present conductance …

One-dimensional (1D) quantum wires exhibit a conductance feature near 0.7× 2 e 2∕ h in
connection with many-body interactions involving the electron spin. With the possibility of …

We report a study of one-dimensional subband splitting in a bilayer graphene quantum point
contact in which quantized conductance in steps of 4 e 2/h is clearly defined down to the …

Abstract Effects of spontaneous spin polarization in quantum point contacts (QPC's) are
investigated for a realistic semiconductor device structure using the Kohn-Sham local spin …

The spontaneous magnetization of a quantum point contact (QPC) formed between two
large quantum dots by a lateral confinement of a high-mobility two-dimensional electron gas …

We present findings for the 0.7 (2e 2/h) feature in the hole quantum conductance staircase
that is caused by silicon one-dimensional channels prepared by the split-gate method inside …

We study nonlinear transport in a clean one-dimensional wire fabricated by cleaved edge
overgrowth in molecular beam epitaxy. At low electron densities, and with a large applied …
