Femtosecond chirp-free studies of energy relaxation in semiconductor quantum dots: Search for a phonon bottleneck
Conference
·
OSTI ID:524984
Contrary to the predictions of phonon bottleneck theories, we observe very fast subpicosecond energy relaxation in strongly confined semiconductor nanocrystals with electron level spacing as large as 20 LO phonon energies.
