Detection device for detecting gas within operating temperature range of detection device, has electrically conductive metal electrode and rear electrode made of metal or semiconductor material

摘要

The detection device has an electrically conductive metal electrode and a rear electrode (102) made of metal or semiconductor material. A dielectric thin layer is arranged between the metal electrode and the rear electrode. A contact of the metal electrode and a contact of the rear electrode are contacted for determining an electrical characteristic assigned to the gas so that the gas is detected by the assigned electrical characteristic. An independent claim is also included for a method for detecting a gas within an operating temperature range of the detection device.
