摘要

Polypeptide based molecular diode with high rectification ratio (∼122 at ±0.422 V) is formed by controlling molecular order and orientation. A film of tethered poly(γ -benzyl-L-glutamate) (PBLG) with high degree of molecular orientation was formed by solvent pair (good/bad) treatment. I-V characterization of the well aligned polypeptides showed that the rectification ratio of PBLG was sufficiently large for potential diode and transistor applications.
