Molecular Electronics Special Feature: Molecular electronics: Some views on transport junctions and beyond

@article{joachim05:8801, abstract = {The field of molecular electronics comprises a fundamental set of issues concerning the electronic response of molecules as parts of a mesoscopic structure and a technology-facing area of science.
