SUMMARY:Excitons\, Disorder\, and Nonequilibrium Transport in Hybrid Semic
 onductor Nanomaterials - William A. Tisdale\, MIT
DTSTART:20201207T140000Z

CONTACT:Mengxia Liu
DESCRIPTION:Structure\, surface chemistry\, and energetic disorder can dra
 matically affect excited state dynamics in low-dimensional systems. Using 
 a combination of ultrafast laser spectroscopy\, time-resolved optical micr
 oscopy\, and kinetic modeling\, I will show how these effects manifest in 
 assemblies of colloidal quantum dots (QD) and 2D halide perovskites. In pa
 rticular\, I will discuss the impact of nonequilibrium population dynamics
  on excited state transport phenomena and the emergence of extraordinary v
 ibrational and thermal phenomena in hybrid organic-inorganic structures.
