SUMMARY:Quantum wire dots and quantum posts\, R. G. Herb Condensed Mat
 ter Seminar\, Craig Pryor\, University of Iowa
DESCRIPTION:The theoretical understanding of the electronic and optica
 l properties of strained semiconductor nanostructures\, such as quantu
 m dots\, has been quite successful\, in spite of the uncertainties in 
 the composition and geometry of the structures\, and the material prop
 erties.  As experimentalists have developed more exotic structures\, s
 uch as nanowire quantum dots and quantum posts\, additional complicati
 ons arise.  For example\, nanowires typically have a different crystal
  structure from the bulk materials\, and large quantum posts can confi
 ne 5 or 6 electrons. I will discuss the progress in understanding of t
 hese structures\, including calculations of strain and material segreg
 ation effects\, electron-electron interactions\, and exciton lifetimes
