The influence of Auger recombination on the performance of quantum-dot light-emitting diodes
Wan Ki Bae, Young-Shin Park, Jaehoon Lim +7
A growing interest in colloidal quantum dot (QD) based light-emitting diodes (QD-LEDs) has been motivated by the exceptional color purity and spectral tunability of QD emission as…
Influence of the Core/Shell Interface on Biexciton Auger Recombination in Individual Nanocrystal Quantum Dots
Young-Shin Park, Wan Ki Bae, Lazaro A. Padilha +2
Previous single-particle spectroscopic studies of colloidal quantum dots have indicated a significant spread in biexciton lifetimes across an ensemble of nominally identical nanocr…
Tunable magnetic exchange interactions in manganese-doped inverted core/shell ZnSe/CdSe nanocrystals
David A. Bussian, Scott A. Crooker, Ming Yin +3
Magnetic doping of semiconductor nanostructures is actively pursued for applications in magnetic memory and spin-based electronics. Central to these efforts is a drive to control t…
Time- and Polarization-Resolved Optical Spectroscopy of Colloidal CdSe Nanocrystal Quantum Dots in High Magnetic Fields
Madalina Furis, Jennifer Hollingsworth, Victor I. Klimov +1
In an effort to elucidate the spin (rather than charge) degrees of freedom in colloidal semiconductor nanocrystal quantum dots, we report on a series of static and time-resolved ph…
Bright-Exciton Fine Structure and Anisotropic Exchange in CdSe Nanocrystal Quantum Dots
M. Furis, H. Htoon, M. A. Petruska +3
We report on polarization-resolved resonant photoluminescence (PL) spectroscopy of bright (spin-1) and dark (spin-2) excitons in colloidal CdSe nanocrystal quantum dots. Using high…
