Abstract

Negative diagonal magneto-conductivity/resistivity is a spectacular- and thought provoking-property of driven, far-from-equilibrium, low dimensional electronic systems. The physical response of this exotic electronic state is not yet fully understood since it is rarely encountered in experiment. The microwave-radiation-induced zero-resistance state in the high mobility GaAs/AlGaAs 2D electron system is believed to be an example where negative magneto-conductivity/resistivity is responsible for the observed phenomena. Here, we examine the magneto-transport characteristics of this negative conductivity/resistivity state in the microwave photo-excited two-dimensional electron system (2DES) through a numerical solution of the associated boundary value problem. The results suggest, surprisingly, that a bare negative diagonal conductivity/resistivity state in the 2DES under photo-excitation should yield a positive diagonal resistance, with a concomitant sign reversal in the Hall voltage.

摘要

负对角磁导率/电阻率是受驱动的、远离平衡的低维电子系统所具有的一种引人注目的且发人深省的特性。这种奇异电子态的物理响应尚未得到充分理解，因为它在实验中很少出现。高迁移率GaAs/AlGaAs二维电子系统中微波辐射诱导的零电阻态被认为是负磁导率/电阻率导致所观察到现象的一个例子。在此，我们通过相关边值问题的数值解来研究微波光激发二维电子系统（2DES）中这种负电导率/电阻率态的磁输运特性。令人惊讶的是，结果表明，光激发下2DES中的裸负对角电导率/电阻率态应产生正对角电阻，同时霍尔电压的符号会反转。
