Figure 3

Macroscopic and microscopic opto-electronic characteristics of the organic blends. (a, b) Macroscopically measured current-voltage characteristics of the blend films under illumination (white light, 80 mW) in the nitrogen atmosphere (0 h) and after exposure to ambient air for 2 and 6 h. The inset images in (a, b) show AFM topography images of the blend films (1 × 1 μ m2, height scale 30 nm). (c, d) Cross sections of the KFM images (shown as insets, 1 × 1 μ m2, potential scale 40 mV) under repeated on/off switching of illumination.
