摘要: This letter demonstrates the characteristics of a resistive switching memory [resistive random access memory (RRAM)] device with a bilayer structure of aluminum-zinc-tin-oxide (AZTO) and HfO2-film layers. As for the RRAM operation, the formation and rupture processes of the conductive filaments can be confined in the HfO2 layer with low-concentration oxygen vacancy. The resistive switching stability and electrical uniformity of bilayer AZTO/HfO2 RRAM device are obviously enhanced as compared with the one only with a single layer of AZTO film. In addition, a physical mechanism for uniformity improvement is proposed by the localized conduction of conducting filaments.
