摘要
Molecular organic materials offer the promise of unique electronic devices but also present challenges for understanding charge transport in narrow-band systems. Low-temperature studies elucidate fundamental transport processes. We report the lowest-temperature field-effect transport results on a crystalline oligomeric organic material, rubrene. We find field-effect switching with an on-off ratio up to 10(7) at temperatures down to 10 K. Gated transport shows a factor of similar to 10 suppression of the thermal activation energy in the 10-50 K range and nearly temperature-independent resistivity below 10 K.
