Abstract

See full text

An electronic device is provided, including: a first drive electrode; a second drive electrode that is spaced apart from the first drive electrode; and a topological insulator that contacts both of the first drive electrode and the second drive electrode and has magnetism, wherein the topological insulator includes a first region having a first coercivity and a second region having a second coercivity that is different from the first coercivity. A fabrication method of a topological insulator is also provided, including: preparing a topological insulator having magnetism and a first coercivity; and forming a second region having a second coercivity that is different from the first coercivity by irradiating a partial region of the topological insulator with ions.
