| 1 | Ultralow switching voltage and power consumption of GeS_(2)thin film resistive switching memory显示文摘The coming Big Data Era requires progress in storage and computing technologies.As an emerging memory technology,Resistive RAM(RRAM)has shown its potential in the next generation high-density storage and neuromorphic computing applications,which extremely demand low switching voltage and power consumption.In this work,a 10 nm-thick amorphous GeS_(2)thin film was utilized as the functional layer of RRAM in a combination with Ag and Pt electrodes.The structure and memory performance of the GeS_(2)-based RRAM device was characterized-it presents high on/off ratio,fast switching time,ultralow switching voltage(0.15 V)and power consumption(1.0 pJ and 0.56 pJ for PROGRAM and ERASE operations,respectively).We attribute these competitive memory characteristics to Ag doping phenomena and subsequent formation of Ag nano-islands in the functional layer that occurs due to diffusion of Ag from electrode into the GeS_(2)thin film.These properties enable applications of GeS_(2)for low energy RRAM device. | N.Lyapunov C.H.Suen C.M.Wong Xiaodan Tang Z.L.Ho K.Zhou X.X.Chen H.M.Liu Xiaoyuan Zhou J.Y.Dai | 2021 | Journal of Advanced Dielectrics2021，11，1： | 0 |
