摘要
我们成功地揭示了含有一系列直线位错的宏观半导体样品中空穴的Aharonov-Bohm型干涉。这种干扰在氦温度下被观察到，在流过晶格不匹配的GaAs 1-x Sb x /GaAs异质结构的p + -n结的正向电流中出现振荡，同时作为垂直于电流的磁场的函数进行测量。当遇到错配位错的里德圆柱体的初级孔波与完全绕圆柱体旋转的波相干扰时，振荡周期就产生了。
Aharonov-Bohm Interference of Holes at Dislocations in Lattice-Mismatched Heterostructures
We have succeeded in revealing Aharonov-Bohm type interference of holes in macroscopic semiconductor sample containing an array of straight-line dislocations. This interference has been observed at helium temperatures as oscillations in the forward current flowing through p + -n junction of the lattice-mismatched GaAs 1-x Sb x /GaAs heterostructure while measured as a function of the magnetic field perpendicular to the current. The oscillation cycles arise when a primary hole wave meeting the Read's cylinder of a misfit dislocation interferes with a wave which circled completely round the cylinder.
