Abstract: Intense, ultrafast photoexcitation of semiconducting materials produces several discrete but inter-related energy relaxation processes that span large spatial and temporal scales [1]. Initial charge-carrier excitation, and generation of a dense electron-hole plasma, produces hypersonic plasma… read more here.
