a Schematic illustrations of a metal-filament-based selector under different applied voltage (Va). b Representative current–voltage (I–V) characteristics of a Cu/Ag metal-filament-based selector, the ON/OFF ratio corresponds to the current variation at the read voltage (Vread) and half-read voltage (Vread/2). c I–V characteristics of Ag/SiO2/Ag, Cu/SiO2/Cu and CuAg/SiO2/CuAg selectors before annealing. d Surface morphologies of Ag/SiO2/Ag, Cu/SiO2/Cu and CuAg/SiO2/CuAg devices before and after annealing in Ar atmosphere at 400 °C for 1 h. e I–V characteristics of annealed Ag/SiO2/Ag, Cu/SiO2/Cu and CuAg/SiO2/CuAg selectors. f XRD patterns of the Ag, Cu and CuAg films on SiO2/Si substrates.
