ABSTRACT
Downscaling of inorganic electronics has currently become in-
creasingly difficult due to both physical limitations such as
modification of electronic structure due to increasing relation
between surface and volume as well as increasing fabrication
costs of top-down structures. Since last decades, especially after
Moore law has shown saturation trend, interest has been gradually
building up in alternative concepts providing strong reduction
of the electronic devices at reasonable prices. Originated in the
seventies (Mann and Kuhn, 1971), molecular electronic concept of
single molecules or small groups of molecules conducting electrical
current between two electrodes is among the most promising
candidates to create future devices capable substitute traditional Si-
based electronics (Nitzan and Ratner, 2003). It has been realized;
however, that electron transport in molecular or organic tunnel
junctions (OTJs) is much more complex than initially thought
(Galperin et al., 2007).
