Professional Summary

Personal Web Page:  http://homepages.uc.edu/~smithlm/
Leigh Smith is a condensed matter experimentalist who looks at the electronic, phononic, and spin properties of semiconductors and semimetals.  His most recent work has been on Topological Insulators and Weyl Semimetals.

Education

Ph.D.: University of Illinois at Urbana-Champaign 1988

BA: University of Virginia Charlottesville, VA, 1982 (Physics and Mathematics with Highest Honors)

Research and Practice Interests

My main areas of interest lie in the physics of electronic states in semiconductor nanostructures:  cofinement potentials, wavefunctions, many body effects, and interactions with phonons, photons, or impurities.  A general theme of my research is to combine:

(a) ultrahigh spectral resolution: to determine the energetics of these states with micro-eV precision. 

(b) sub-micron spatial resolution: to isolate single quantum confined states, or measure the transport properties of neutral particles.

(c) picosecond temporal resolution: to measure the dynamics of interactions between these various states.

to achieve a more complete picture of these electronic states and their interactions. 

In particular, my research publications can be divided into several areas:  (1) semiconductor nanowire heterostructures, (2) quantum dots and their excitons, (3) exciton spins and magnetic impurities, (4) exciton transport and interactions with spins or phonons, (5) many-body effects in semiconductors.
