Abstract:
1. A method of making a metal oxide film, the method comprising: a step of forming a metal film having a (111) plane, on a base material; a step of directly forming a metal oxide film on the (111) plane of the metal film; and a step of maintaining a temperature of the metal oxide film at 300-400° C. and irradiating the metal oxide film with UV light to obtain a crystalline metal oxide film, wherein the metal oxide film is BaTiO the UV light is pulsed laser light having energy of 70-90 mJ/cm the obtained crystalline metal oxide film after the step of maintaining a temperature and irradiating the metal oxide film is orientated to (100) plan; a repetition rate of the pulsed laser light is 1-100 Hz, and a number of shots is from 100 to 10,000.
