â¢Amorphous SiC with embedded Cu nanoparticles (a-SiC:Cu) was investigated as the insulator layers for Cu/a-SiC:Cu/Au resistive memory.â¢Forming voltage and SET voltage reduced with increased Cu%.â¢Large ON/OFF ratio up to 107 were observed for all Cu/a-SiC:Cu/Au resistive memories.â¢Endurance over repeated switching was improved with increased Cu%.
Amorphous SiC with embedded Cu nanoparticles (a-SiC:Cu) was investigated as the insulator layer of Cu/a-SiC:Cu/Au resistive memory. The effect of the Cu embedding on resistive switching characteristics was studied for 20 and 30Â vol% Cu. Reduced forming and SET voltages and increased endurance was observed for devices with 30Cu%. At the same time, all key advantageous characteristics of amorphous SiC resistive memory such as ON/OFF ratio of 107 and the co-existence of bipolar and unipolar modes were maintained upon Cu embedding. All above suggests that Cu embedding could be considered as a promising method to improve the overall performance of Cu/a-SiC:Cu/Au resistive memories.
