- Abstract
Semi‐floating gate (SFG) memory based on 2D materials shows ultrahigh‐speed operations and fills the huge gap between volatile memory and nonvolatile memory technology in time scale. In this study, a SFG FET with a programmable rectification mode based on the 2D WS2 is achieved. The innovative use of the quasi‐non‐volatile programmable p–n junction photovoltaic effect successfully provides an ultra‐low power consumption photovoltaic quasi‐non‐volatile memory. The device exhibits a switching ratio of more than 107 at constant drain‐source voltage Vds = ±5 V. In the p–n junction mode, after removing the gate voltage for 1 h, the rectification ratio of the device is 105. Combined with ultra‐fast operation speed, which can provide perspectives on possible directions of the next generation for low‐power high‐speed semi‐floating gate FET applications.
