Excited-state relaxation in group IV nanocrystals investigated using optical methods

Abstrakt

The chapter reviews experimental optical methods used for investigating electronic excited states in nanostructures and their relaxation in time (pump and probe, up-conversion technique, transient grating technique, time-resolved terahertz spectroscopy). A review of typical results in Si and Ge is given
