Control of conductance in a quasi-1D channel in the presence of spin-orbit coupling

The electron energy spectrum and conductance in a quasi-1D channel with spin-orbit coupling is calculated. The channel is divided into two parts by a potential barrier. It is shown that a change in the barrier electric potential yields additional extema of the function ɛ( k ). This results in modifi...

Description
Summary:The electron energy spectrum and conductance in a quasi-1D channel with spin-orbit coupling is calculated. The channel is divided into two parts by a potential barrier. It is shown that a change in the barrier electric potential yields additional extema of the function ɛ( k ). This results in modification of the conductance quantization law. The quantum states and conductance are calculated for the parameters of real structures with weak both and relatively strong spin-orbit coupling.
