Electronic processes in polyazomethine thin films

This paper is focused on thin films of various aromatic polyazomethines, undoped and doped with iodine and FeCl3, which are expected to be promising materials for organic electronics. Polyazomethine thin films have been fabricated by thermal vacuum evaporation (TVE) and chemical vapor deposition...

Polyazomethine thin films have been fabricated by thermal vacuum evaporation (TVE) and chemical vapor deposition (CVD) via the polycondensation process. The prepared films, with a typical thickness of the order of 100 nm and smooth surfaces, appear to be considerably amorphous.
