Rob Coalson carries out theoretical modeling of several types of
nanoscopic systems. His group investigates light transmission
through 1-100 nanometer structures including colloid crystal
arrays and thin films with patterned arrays of holes or
scatterers in them. He is especially interested in possible uses
of superconducting materials as elements in nano-patterned
materials with unusual and tunable optical properties (e.g.,
optical band gaps or enhanced light transmission). Coalson is
also engaged in modeling biological ion channels (typically a
few nanometers in length and less than 1 nanometer in diameter),
with particular focus on utilizing these proteins as
bio-batteries and single-molecule sensing devices.

a dielectric medium: a band gap (between ca. 0.2 and 0.4
on the ordinate axis) is clearly apparent. |
