Аннотация:
Application of sol-gel derived titania nanoparticles in memristive thin film devices has been a subject of several studies. The reported data on the functional properties and stability of such devices scatter considerably. Meanwhile, the role of post-fabrication treatment, such as annealing in reducing atmosphere, is still poorly investigated for this class of devices. In this study, the effects of thermal annealing in a reducing atmosphere on the resistive switching behavior and the morphological changes of the top electrode during the electroforming process have been systematically addressed for the samples of Al/TiO$_2$/FTO thin film memristors prepared using sol-gel derived titania. Manifestations of several phenomena affecting the functional stability of these thin films, such as electrode delamination and collapse due to formation of gas bubbles, appearance of electrochemical patterns at the electrode surface, and morphological changes induced by the electroforming process have been systematically established in relation with the various conditions of thermal treatment in a reducing atmosphere.
