Leigh Smith has been a faculty member of the Department of Physics since 1990. He received his BA degree with Highest Honors in Mathematics and Physics from the University of Virginia in 1982. After spending a year in the graduate program in Physics at Princeton University, he began his PhD research in the group of James P Wolfe at the University of Illinois in Urbana-Champaign. While at Illinois, he received fellowships from the National Science Foundation, IBM and Shell Oil Company. He was awarded a PhD in Physics in 1988 and worked for two years as a Postdoc in the group of Donald Wolford at the IBM Thomas J. Watson Research Center in Yorktown Heights, NY before arriving at the University of Cincinnati.

Education

  • Ph.D., University of Illinois at Urbana-Champaign, 1988.
  • BA, University of Virginia, Charlottesville, VA, 1982 (Physics and Mathematics with Highest Honors).

Research Information

Research 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.
