Thin layer gas sensor

摘要

Thin layer gas sensor comprises: (a) a heatable metal oxide layer (1); (b) a 1<st> electrode arrangement (2) contacting the metal oxide layer; and (c) a 2<nd> electrode arrangement (3) contacting the metal oxide layer. The novelty is that the contact is formed between the 1<st> electrode arrangement and the metal oxide layer Schottky contact, and between the 2<nd> electrode arrangement and the metal oxide layer as Ohmic contact.
