Abstract
An electric-field-sensitive element (1) includes: an optical function layer (5) that includes a metal oxide selected from the group consisting of tin dioxide, titanium dioxide and zinc oxide, and an insulating material covering the metal oxide, the optical function layer (5) having a visible light transmittance that changes through application of an electric field; and a first and second electrode layer (7, 9) that sandwich the optical function layer (5) therebetween.
Claims2
A method of modifying the structure of a metal oxide, the method comprising the steps of:
- disposing a metal oxide selected from the group consisting of tin dioxide, titanium dioxide, and zinc oxide and covered with an insulating material in contact with a conductive layer, and
- irradiating ultraviolet light to the metal oxide covered with the insulating material, thereby forming a number of energy levels with no electrons in the band gap of the metal oxide.
A metal oxide selected from the group consisting of tin dioxide, titanium dioxide, and zinc oxide,
- wherein the surface of the metal oxide is covered with an insulating material and ultraviolet light is irradiated in a state where the insulating material is in contact with a conductive layer, and number of energy levels with no electrons are formed in the band gap of the metal oxide.
