Molecular Electronics (Moletronics)
has opened up a new frontier aiming at ultimate miniaturization of
electronic circuits with ultra high
density electronic components. Pati's research primarily focused on
addressing the fundamental challenges in molecular electronics by understanding
the complex phenomena like "controlled electron transport" in
molecular wires, which forms the basis of molecular electronics. He has published
several research articles in this area. One of his recent paper is on "conformational
molecular switch", which he published with his collaborator Dr.
S. P. Karna from the Army Research Laboratory. They
found the molecular wire (Fig.1) exhibiting current switching between the
planar and perpendicular orientations of the two pi-electron moieties with
planar configuration (ON state) giving significantly higher current than
the perpendicular conformation (OFF state).
