Abstract
The gasistor is a device, which combines gas sensing and resistive switching in a single capacitor-like metal/metal oxide/metal cell. It works as a gas sensor with memristive memory or as a thyristor-like switch triggered by a change in the target gas concentration. The same metal oxide layer and the same cell used for gas-sensing is also used for resistive switching. The mutual entanglement of their fabrication parameters impedes the ability to separately adjust the two functionalities. In this work the two parts (sensor and memristor) are developed separately, allowing for their individual tuning, target-ing specific gas concentration and improving the sensitivity of the gasistor device.
