Variability and power enhancement of current controlled resistive switching devices Vinuesa, G Aguilera Pedregosa, Cristina Moreno, E. Jiménez Molinos, Francisco Roldán Aranda, Juan Bautista Resistive switching Hafnium oxide Current control Electrical characterization TCM RRAM characterized using both current and voltage sweeps, with the device resistance and its cycle-to-cycle variability being analysed in each case. Experimental measurements indicate a clear improvement on resistance states stability when using current sweeps to induce both set and reset processes. Moreover, it has been found that using current to induce these transitions is more efficient than using voltage sweeps, as seen when analysing the device power consumption. The same results are obtained for devices with a Ni top electrode and a bilayer or pentalayer of HfO2/Al2O3 as dielectric. Finally, kinetic Monte Carlo and compact modelling simulation studies are performed to shed light on the experimental results 2023-06-23T06:53:55Z 2023-06-23T06:53:55Z 2023-04-15 journal article G.
