(a) Room temperature double-sweep Ids−Vg characteristics (Vds=−0.5 V), with little hysteresis. Black and blue lines are drawn in linear and log scales, respectively. (b) Ids−Vds characteristics of the device in a. From top to bottom, Vg=−10 V, −25 V, −30 V, −35 V and −40 V, respectively. Inset shows the optical microscopy image of the device. Scale bar, 16 μm. (c) The extracted μ−Vg relationship at room temperature. The peak mobility is over 10 cm2 V−1 s−1 for this device.
