摘要
Single-crystal CoGa has been grown on GaAs(100) by molecular-beam epitaxy. The CoGa/GaAs interface has been characterized using weak-beam and high-resolution transmission electron microscopy. The misfit dislocations at the CoGa/GaAs interface are determined by the CoGa lattice. The interface dislocations in systems like CoGa/GaAs thus show important differences in comparison to those in the more extensively studied mismatched semiconductor systems.
