摘要: The formation of a Ba-Te surface on GaAs has been investigated. was created using molecular beam epitaxy (MRS). A (100) first exposed to Te and characterized x-ray photoelectron spectroscopy (XPS), reflective high energy electron diffraction (RHEED) low (LEED). Te-reacted then BaF 2 flux producing second reaction. In this reaction, the dissociated leaving barium but no fluorine. This is in contrast clean (no tellurium) which shown grow single crystal. Although order exists during early stages growth, further exposure gives way polycrystalline form. paper discusses analysis surface.
