James R. McBride

Research Associate Professor of Chemistry

Research:

James is interested in applying advanced electron microscopy techniques towards the understanding of the structure-property relationships of colloidal quantum dots. In collaboration with Stephen Pennycook and Andrew Lupini at ORNL, he has utilized aberration-corrected electron microscopy to image the true structure of core/shell nanocrystals. With the newly added Tecnai Osiris at Vanderbilt, James has been employing this instrument’s state-of-the-art energy dispersive spectroscopy (EDS) system to map the chemical composition of doped Si nanowires and graded alloy nanocrystals. His primary efforts currently involve correlating the atomic structure and the photoluminescence of the same quantum dot.

James manages and trains graduates students on the Tecnai Osiris TEM/STEM at Vanderbilt.
