Organic thin-film transistor structure

Fig. 1.3. Schematic view of the structure of organic thin film transistors. Both structures are top-gated, (a) Bottom contact (BC) (b) Top contact (TC).

Fig. 13.1. Schematic structure of the organic thin-film transistor. Starting from the bottom, the transistor consists of the following layers substrate (brown), gate electrode G, (yellow), gate insulator layer (red), the source, S, and drain, D, electrodes (yellow), semiconductor (grey).

Figure 5b shows the structure of an organic thin-film transistor. The transistor consists of an organic thin film on top of a gate insulator contacted by metal source and drain electrodes. The gate insulator could be...
