<p>A. the field of the invention written in the claims: Ultraviolet-ray sensing element.B. subject of the art to be overcome by the present invention: To provide a good ultraviolet sensing element which enables back irradiation and front irradiation without a buffer layer. C. point of the solution of the present invention: The ultraviolet sensing element comprises an optical absorption layer epitaxial grown on a substrate; a Schottky layer schottky-junctioned to a portion of the optical absorption layer; and a pair of ohmic contact layers spaced apart from each other, defining a pair of electrodes each of which has an ohmic contact with the optical absorption layer, and spaced apart from the Schottky layer on the optical absorption layer.</p> |
