Abstract

The temperature dependence of resistive switching of Cr 0.2at%-doped SrZrO₃ (Cr:SZO) thin films grown on SrRuO₃/Si(100) substrates by using radio frequency sputtering has been studied over the temperature range between 300 K and 10 K. The film has a polycrystalline structure. Good and reproducible ON and OFF resistive switching is observed. While the low-resistance ON state show a metallic behavior, the high-resistance OFF current shows a thermal activation behavior. Using an Arrhenius plot, we estimated the barrier height of the initial (before forming) and the OFF states to be ∼24.2 meV and ∼2.14 meV, respectively.
