Latha Venkataraman and her group measure the fundamental properties of single molecule devices, seeking to understand the interplay of physics, chemistry, and engineering at the nanometer scale. The underlying focus of her research is to fabricate single molecule circuits, a molecule attached to two electrodes, with varied functionality, where the circuit structure is defined with atomic precision. She measures electronic conduction, single bond breaking forces, thermoelectric and electrochemical properties of these devices. Her interdisciplinary and collaborative research, working together with synthetic chemist and theory groups, provides a deeper understanding of the fundamental physics of electron transport, while laying the groundwork for technological advances at the nanometer scale. Besides advancing the field of nanoscale electronics, her work has also broadened understanding of charge transfer at metal/organic interfaces which has impact on the fields of organic electronics, photovoltaics, catalysis, and charge transfer processes in biological systems.

Research Interests

Single-Molecule Electronics, scanning tunneling microscopy, atomic force microscopy, nanoscale transport, electrochemistry, photoconduction, x-ray photoemission spectroscopy

Research Areas

Latha Venkataraman received her Bachelor’s degree in Physics from Massachusetts Institute of Technology in 1993 where she did her undergraduate thesis with Prof. Mildred Dresselhaus.  She then moved to Harvard University and obtained her Ph. D. in 1999 working under the guidance of Prof. Charles Lieber. She worked as a research scientist at Vytran Corporation from 1999 to 2002. In 2003, she joined Columbia University as a research scientist. She started her independent career as an assistant professor in the Department of Applied Physics and Applied Mathematics at Columbia University in 2007. She is currently Professor of Applied Physics and Applied Mathematics and holds a joint appointment with the Department of Chemistry.
