WebFeb 16, 2016 · However the Al/AlO x (water)/AlO x (ozone)/Pt RRAM devices have restricted set and reset area, resulting in good uniformity and reliability. To ensure the different amounts of V o s between AlO x (water) and AlO x (ozone) layer, top electrode is active Al which contacts the AlO x (water) layer and increases the number of V o s in AlO x (water). WebAbstract: For the first time, a new technical solution is presented to essentially improve the uniformity of oxide based RRAM devices by using material design methodology based on first principle calculations. The results indicate that doping of trivalent elements such as Al, La, or Ga into the tetravalent metal oxides such as HfO 2 or ZrO 2 effectively controls the … dr josh tucker charleston wv
