Abstract
We suggest a possible mechanism for bipolar switching in a Pt/TiO2 / Pt resistive switching cell in terms of electrochemical reactions involving oxygen ions/vacancies. The electrochemical reactions are considered to take place at an interface between Pt and TiO2 solid electrolyte, and they modulate the Schottky barrier height at the interface. Calculation results using this proposed mechanism can explain a bipolar switching behavior and semiquantitatively describe experimental data.
