Abstract

ZnO semiconductor oxides are versatile functional materials that used in photoelectronic, catalysis, sensing, etc. The Zn^+-O^- surface electronic states of semiconductor oxides were formed on ZnO’s surface by Zn 4s, O 2p orbitals coupling with the diboron compound’s B 2p orbitals. The formation of spin coupled surface states was based on the spin orbit interaction on the interface, which has not been reported before. It shows that the semiconductor oxide’s spin surface states can be modulated by regulating surface orbital energy. The Zn^+-O^- surface electronic states were confirmed by ESR results, which may help expand fundamental research on spintronics modulation and quantum transport.
