Rectification Mechanism in Diblock Oligomer Molecular Diodes
Physical Review Letters
We investigated a mechanism of rectification in di-block oligomer diode molecules that have recently been synthesized and showed a pronounced asymmetry in the measured I-V spectrum. The observed rectification effect is due to the resonant nature of electron transfer in the system and localization properties of bound state wave functions of resonant states of the tunneling electron interacting with asymmetric molecule in an electric field. The asymmetry of the tunneling wave function is enhanceddoi:10.1103/physrevlett.96.096803 pmid:16606295 fatcat:qzi24zvrrnd4rmwtxermkjbtva
