Temperature and gate voltage range-dependent transfer characteristics. a Anti-hysteresis in transfer characteristics with respect to back gate voltage (VBG) at different temperatures showing the decrease in anti-hysteresis with increasing temperature. b Anti-hysteresis in transfer characteristics with respect to VBG at 70 K showing the decrease in anti-hysteresis with decreasing sweep range of VBG. The arrows indicate the direction of VBG sweep in (a, b). c The CNP of forward and reverse sweep directions as a function of overall sweep range of VBG (ΔVBG) at different temperatures for devices D2 and D1 (inset). d The difference in CNP of forward and reverse sweep directions of VBG as a function of temperature at different sweep ranges for devices D2 and D1 (inset)
