摘要：
We report ballistic-electron-emission microscopy (BEEM) imaging and spatially resolved spectroscopy of InxGa1-xAs/GaAs misfit dislocations 800 Angstrom below the surface. Majority-carrier scattering by a fraction of misfit dislocations was seen to locally reduce the BEEM current and to give logarithmic spatial dependence, which suggests charging of the dislocation cores.
