Communication: n-Type-electron transporting-conduction is demonstrated
for Schottky diodes and field effect transistors based on diphenyl-3,
4,9,10-perylenetetracarboxylic-diimide. The role of the electron-injec
ting electrode is discussed, as are the potential improvements in perf
ormance offered by devices combining a p-type semiconducting layer wit
h an n-type, electron transporting organic compound.
