边缘输运和零电阻态的微波稳定化

Microwave stabilization of edge transport and zero-resistance states

A. D. Chepelianskii, D. L. Shepelyansky

摘要:

边缘通道对磁场作用下二维电子气中的电子输运起着至关重要的作用。通常认为沿边缘的弹道输运仅发生在具有低填充因子的量子区域中。我们表明,微波场可以稳定的边缘轨迹,即使在半经典制度导致纵向电阻消失。这种机制给出了一个明确的物理解释所观察到的零电阻状态。

英文摘要:

Edge channels play a crucial role for electron transport in two dimensional electron gas under magnetic field. It is usually thought that ballistic transport along edges occurs only in the quantum regime with low filling factors. We show that a microwave field can stabilize edge trajectories even in the semiclassical regime leading to a vanishing longitudinal resistance. This mechanism gives a clear physical interpretation for observed zero-resistance states.
