Switch-on lag

Caption

The six images shown here are microscope camera screen shots, showing the two-step turn-on process for an OECT. Figures on the left indicate time. When the OECT is first switched on, a dark front of ions propagates across the transistor from the side labeled “S” to the side labeled “D.” Afterward, the transistor continues to darken as additional charge-bearing particles move in.
