A self-rectifying unipolar RRAM based on HfOx dielectrics using highly doped n-type germanium substrate as the bottom electrode is proposed for the first time. The RRAM cells exhibit a stable unipolar resistive switching behavior. Owning to Schottky barrier between defect states in HfOx layer and n-...
