Resistivity switching properties of Li-doped ZnO films deposited on LaB6 electrode
چکیده انگلیسی


• Al/p-ZnO:Li/LaB6 memristive device is fabricated using an e-beam evaporation technique.
• Current–voltage (I–V) characteristics are studied.
• Type of resistive switching mode depends on the bias voltage polarity and number of switching cycles.
• Resistive switching in Al/ZnO:Li/LaB6 has an interfacial effect.
• Ohmic and SCLC laws are responsible for conductivity mechanism of resistive states.

Current–voltage (I–V) characteristics of Al/p-ZnO:Li/LaB6 device, measured in voltage sweep mode, show unipolar resistive switching and monostable threshold switching (URS and MTS) for different bias voltage polarities. URS could be transformed to MTS by application of reverse bias voltage. With increasing number of cycles, URS is converted to bipolar resistive switching mode which is lost after certain number of cycles, and device turns into an ordinary resistor. Analysis of linear fitting I–V curves suggests that ohmic and space charge limited current laws are responsible for conductivity mechanism of Al/p-ZnO:Li/LaB6 device.
