摘要: Interfaces between C60 and electrode materials (gold (Au) or indium tin oxide (In2O3 + SnO2 10 wt%, ITO)) have been investigated by means of optical absorption. For the bi-layer Au, a clear shift in onset absorption at long wave length (λ) region originated from Au was observed. This can be attributed to red plasma frequency decrease electron density Au. On other hand, for ITO, enhancement observed λ> 300 nm. The origin is suggested low energy charge transfer ITO C60, which consistent with Schottky barrier height interface. Our results suggest that electronic structures around interface an organic semiconductor inorganic metal are modified material.
