Direct Observation of Dark Excitons in Individual Carbon Nanotubes: Role of Local Environments
A. Srivastava, H. Htoon, V. I. Klimov +1
We report the direct observation of the spin-singlet dark excitonic state in individual single-walled carbon nanotubes through low-temperature micro-photoluminescence spectroscopy…

Carrier Multiplication in Nanocrystals via Photostimulated Generation of Biexcitons from Vacuum
Valery I. Rupasov, Victor I. Klimov
We propose a novel mechanism for photogeneration of multiexcitons by single photons (carrier multiplication) in semiconductor nanocrystals. In this mechanism, the Coulomb interacti…

Picosecond energy transfer in quantum dot Langmuir-Blodgett nanoassemblies
Marc Achermann, Melissa A. Petruska, Scott A. Crooker +1
We study spectrally resolved dynamics of Forster energy transfer in single monolayers and bilayers of semiconductor nanocrystal quantum dots assembled using Langmuir-Blodgett (LB)…
