RESEARCH
We have investigated mesoscopic electronic transport in
a number of low-dimensional systems, such as
quantum dots and single
impurities. Recent work has investigated the
states of impurities in Schottky barrier MOSFETs (pictured
right), where we have observed the first Stark effect splitting
of a single impurity (PRL, in press).
The lab investigates the electronic and optical properties
of a variety of nanowires. In electronic transport devices,
we are looking at new growth capabilities to explore
low-dimensional physics. In nanophotonics, we have
discovered new mechanisms for surface plasmon-polariton
(SPP) generation, and are investigating the control and
manipulation of SPPs on the ultra-subwavelength scale.
We have
pioneered transport in molecular-scale systems -
recent work has concentrated on utilizing inelastic electron tunneling
spectroscopy (IETS) for the detailed understanding of
molecular environment and configuration.
