Over the years, research in the Baker group has
encompassed an eclectic mix, ranging from applications of spectroscopic
techniques (mainly photoelectron spectroscopy) to organic synthesis and
mechanisms, photophysics of coordination compounds, and DNA intercalation
phenomena (see Publication list for specifics).
For the 2008-2009 academic year, I was granted a
sabbatical leave, and decided to move into another new area – fundamental
studies of crystalline ionic and molecular materials using computational
methods. This work is in collaboration with Prof. Mark Baker of the
University of Guelph in Canada. It has already produced novel results, and
two manuscripts are under review as of Dec 2008. Links will be posted here
when the articles are published.
.
They describe a new and simpler method for computing
Madelung constants, and a detailed study as to how Madelung Constants
evolve for ions at various sites in crystals (edges, corners, face centers,
body centers, etc.) en route from nanostructures to bulk structures.
Ongoing work involves applications of this methodology to a range of crystal
types, and to molecular solids such as C60.
The figure shows a color –coded “map” of the Madelung
Constants for an uncharged zinc blende nanostructure containing 136 ions.
