Query: Rectification Mechanism in Di-Block Oligomer Molecular Diodes   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 enhanced or weakened depending on the polarity of
applied bias. The conceptually new theoretical approach, the Green's function
theory of sub-barrier scattering, is able to provide a physically transparent
explanation of this rectification effect based on the concept of the bound
state spectrum of a tunneling electron. The theory predicts the characteristic
features of the I-V spectrum in qualitative agreement with experiment.
