借助于格林函数方法,研究了二维无序电子系统子带间杂质散射对电导率和霍耳系数的量子相干修正的影响。结果表明当电子从单带占据过渡到双带占据时,电导率和霍耳系数均发生跨越行为。By using the Green's function method, we have studied effect of intersubband impurity scattering on the quantum correlation of conductivity and Hall coefficient. It is shown that crossover behaviors appears in both coductivity and Hall coefficient when the situation changes from one-subband occupation to two-subband occupation.
