Figure 5. Uniformity of the short-time spin-coating method.

Figure 5

The average field-effect mobility in P3HT films that had been spin-cast for various spinning times: (a) 3s, (b) 5s, (c) 10s, (d) 30s, and (e) 60s. (f) The average field-effect mobility in the drop-cast P3HT films. The figures reveal the uniformity of the method. The gradation of colors revealed the field-effect mobility of a unit cell within a one inch square wafer, for each sample.
