Anatomy of vertical heteroepitaxial interfaces reveals the memristive mechanism in Nb(2)O(5)-NaNbO(3) thin films

Dynamic oxygen vacancies play a significant role in memristive switching materials and memristors can be realized via well controlled doping. Based on this idea we deposite Nb(2)O(5)-NaNbO(3) nanocomposite thin films on SrRuO(3)-buffered LaAlO(3) substrates. Through the spontaneous phase separation...

description Dynamic oxygen vacancies play a significant role in memristive switching materials and memristors can be realized via well controlled doping. Based on this idea we deposite Nb(2)O(5)-NaNbO(3) nanocomposite thin films on SrRuO(3)-buffered LaAlO(3) substrates. Through the spontaneous phase separation and self-assembly growth, two phases form clear vertical heteroepitaxial nanostructures. The interfaces between niobium oxide and sodium niobate full of ion vacancies form the conductive channels. Alternative I-V behavior attributed to dynamic ion migration reveals the memristive switching mechanism under the external bias. We believe that this phenomenon has a great potential in future device applications.
