MoO3 Interlayer Modification on the Electronic Structure of Co/BP Interface

The modification by molybdenum trioxide (MoO3) buffer layer on the electronic structure between Co and black phosphorus (BP) was investigated with ultraviolet photoemission spectroscopy (UPS) X-ray (XPS). It found that MoO3 could effectively prevent destruction of outermost BP lattice during deposition, symmetry remaining maintained. There is a noticeable interfacial charge transfer in addition to chemical reaction MoO3. growth pattern deposited onto MoO3/BP film island mode. observations reveal significance provide help for design high-performance Co/BP-based spintronic devices.
