摘要：

The performance of oligothiophene-based field-effect transistors is thought to be dependent on the nature of the metal/semiconductor/insulator interfaces. The observation of evanescent optical waves in thin films of. for example, alpha-6T (see Figure) provides a non-destructive probe of the charge transfer processes taking place at these interfaces.
