报告摘要：

The  fundamental  length  scales  associated  with  the  basic  heat  carriers,  such  as  phonons, electrons  and  photons,  nerally  fall  in  the  range  of  1-1000  nm.    Therefore,  exploring  and exploiting  basic  nanoscale  thermal  transport  and  conversion  phenomena  hold  the  key  for developing  high  performance  materials  and  devices  for  thermal  energy  conversion  and management. Despite the extensive research progress made in the past decade, some key issues still remain elusive. For example, what are the limits of charge and heat transport when the sizes of nanostructures are approaching the characteristic sizes of the energy carriers? How do we simultaneously  reduce  thermal  conductivity  and  improve  thermoelectric  power  factor in nanostructures for thermoelectric applications? In this presentation, I will discuss our recent work on using rationally designed nanostructures as well as advanced instrumentation to study thermal and thermoelectric transport phenomena in nanostructures in the confinement regime.
