Figure 4. Left: Original OECT with applied electrolyte solution. The electrodes (S: source, D: drain, G: gate) were connected to the semiconductor parameter analyzer via micro-manipulated probe tips. One device contains four pairs of source-drain electrodes (S, D) and one common gate electrode (G). Right: Transfer curve of the original OECT with a channel length and width of 0.5 mm. VG: gate voltage; ID: drain current; VSD: source-drain voltage
