- 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.
