PROJECT TITLE :
Study From Cryogenic to High Temperatures of the High- and Low-Resistance-State Currents of ReRAM Ni–HfO2–Si Capacitors
Resistive switching conduction in Ni/HfO2/Si capacitors is studied at temperatures ranging from seventy seven to 473 K. A model for the low-resistance state (LRS) in step with the experimental knowledge is proposed. The LRS current–voltage ( – ) curves show a maximum resistance, , at zero bias and a minimum worth, , at voltages close to reset, that indicates a departure from linearity. A three-parameter model for the – curves is reported and its temperature dependence analyzed.
