Figure 2

Topmost trace of the output characteristic for V_GS=1V: a) after several hours at roomlight and zero bias (straight line), b) 10s afterwards (dashed line), c) after brief UV-illumination (dash-dotted line). The dotted line shows the topmost trace after pinching off the device for 5 min.

Figure 3

The first 400s of the drain current transients for V_GS=0V and V_DS=100 mV measured for 5 hours in the dark. Before each transient the sample was biased at V_DS⁰=100 mV and the V⁰_GS indicated in the figure.

Figure 4

Drain-current transients measured at different temperatures with V_GS=1 V and V_DS=6 V. Prior to the measurement the device was pre-biased at V_GS⁰=-10 V and V_DS⁰=6 V for 5 min.
