Simulation of Mos2 based Asymmetric Nano-Channel Rectifier

Molybdenum disulfide (MoS2) has been utilized to demonstrate rectification behavior in an asymmetric channel similar to a diode-like I-V response. The demonstrated asymmetric device called self-switching diode is simulated by Silvaco TCAD software. The large signal analysis has been performed to estimate the frequency response. The diode shows NEP and responsivity of 6.50 nW/Hz ^1/2 and 59.11 V/W, respectively. The diode can be used for radio frequency (RF) rectification as it has a cut-off frequency of ~191 MHz.
