Abstract :
We describe the electrical characteristics of thin film transistors with active layers made with /spl alpha/-hexathienylene. The on-conductance in these transistors is two-dimensional. The mobility of field induced carriers and the shape of the current-voltage characteristics depend on the channel length. With interdigitated source-drain regions we have achieved on/off ratios of more than 10/sup 5/.<>
