ZNO-BASED SEMICONDUCTOR ELEMENT

摘要

Provided is a ZnO semiconductor element which uses a ZnO semiconductor and an organic material for active functions and has a completely novel function different from conventional functions. An organic electrode (2) is formed on a ZnO semiconductor (1), and an Au film (3) is formed on the organic electrode (2). On the rear surface of the ZnO semiconductor (1), an electrode made of a multilayer metal film composed of a Ti film (4) and an Au film (5) is formed to face the organic electrode (2). A bonding interface between the organic electrode (2) and the ZnO semiconductor (1) is in a pn-junction-like state, and rectification is generated between the electrode and the semiconductor.
