自旋-轨道相互作用控制的二维超晶格的高温电导

High temperature conductance of a two-dimensional superlattice controlled by spin-orbit interaction

Peter Foldi, Viktor Szaszko-Bogar, F. M. Peeters

摘要:

二维超晶格的Rashba型自旋轨道相互作用(SOI)控制的能带结构允许通过改变SOI的强度来调制有限尺寸器件的电导。我们考虑矩形阵列,发现电导的温度依赖性消失的高温,但SOI的强度仍然影响在这些温度下的电导。即使在存在强退相的情况下也可以看到调制效果,这在实际应用的情况下可能是重要的。

英文摘要:

Rashba-type spin-orbit interaction (SOI) controlled band structure of a two-dimensional superlattice allows for the modulation of the conductance of finite size devices by changing the strength of the SOI. We consider rectangular arrays and find that the temperature dependence of the conductance disappears for high temperatures, but the strength of the SOI still affects the conductance at these temperatures. The modulation effect can be seen even in the presence of strong dephasing, which can be important in case of practical applications.
