Output and transfer characteristics of a hygroscopic insulator field-effect transistor measured in air and an inset of the schematic cross section of the device.
When switching the gate voltage for a constant drain voltage no difference is observed in the linear and saturated regime of the device. The upper part shows the gate voltage while the lower part shows the drain current response for the two different drain voltages.
Switching the pinch-off between the s-d contacts by changing s-d polarity at time reveals that the pinch-off is too slow to be electronic. The upper part of the graph shows the s-d current while the lower part shows the gate current during the pinch-off switch.
Switching the pinch-off (at time ) between the s-d contacts for different constant gate voltages shows that the time response is slower for increasing gate voltages. Function (1) is fitted to the decreasing and the increasing source-drain current, respectively, to estimate the rate constants, and .
