Abstract :
Guanosine molecules have strong dipole moment and can self-assemble in confined space to ribbon-like structure with polarization along its axis. Single molecule current-voltage and photocurrent measurements show that the polarization depends on the ribbon length and affect electric characterization of the MSM structure.
