Abstract
The movement of oxygen ions plays an important role in the resistive switching behavior of TiOx based devices, therefore the designed distribution of oxygen ions may help enhance the oxygen ion's movement and improve the resistive switching performance. In this work, we dope the TiOx thin film with a graded concentration of Ta in depth, to generate a spatial gradient of oxygen activation energy. Detailed characterization of the strcutual changes and resistive switching performance has been carried out, our result may suggest a new way to use dopants to help improve the resistive switching performance.
