FERROMAGNETIC p-TYPE SINGLE CRYSTAL ZINC OXIDE AND METHOD FOR PREPARATION THEREOF

摘要

A thin film of a single crystal ZnO having a high ferromagnetic transition temperature, which comprises a ferromagnetic p-type single crystal zinc oxide containing a transition metal element Mn and a p-type dopant, or a ferromagnetic p-type single crystal zinc oxide containing a transition metal element Mn, an n-type dopant and a p-type dopant. The single crystal zinc oxide of the present invention, being combined with an n-type and/or a p-type transparent ZnO electrode or an optical fiber currently used, can be used in a quantum computer, in high-capacity magneto-optic recording, and in high-performance information and communication as an optoelectronic material usable over a wide range from visible to ultraviolet region.
