Roberts Research Published in the Journal of Physical Chemistry Letters

A new article from the Roberts group has just appeared in the Journal of Physical Chemistry Letters.


In their paper, members of the Roberts lab describe a new spectrometer that they have developed for measuring spectra produced by electronic sum frequency generation (ESFG). ESFG is a nonlinear process that preferentially occurs at surfaces and interfaces. Led by a postdoctoral researcher, Dr. Ravindra Pandey, and a 3rd year graduate student, Aaron Moon, members of the Roberts lab used ESFG to examine the interfacial electronic structure of copper phthalocyanine films relevant to the design of organic electronics. With this technique, the Roberts group can examine interfacial energy and charge transfer processes that occur in molecular electronics in situ, providing information on how to best optimize their performance.
