Highly Charged Excitons and Biexcitons in Type-II Core/Crown Colloidal Nanoplatelets
American Chemical Society (2022-04-28)The optoelectronic properties of type-II CdSe/CdTe colloidal nanoplatelets (NPLs) charged with neutral excitons (X0) have been intensively investigated in the last years. Motivated by the recent experimental progress, here ... -
Hole Band Mixing in CdS and CdSe Quantum Dots and Quantum Rods
American Chemical Society (2010)Using a six-band k·p Hamiltonian for wurtzite lattice, we study the hole ground state symmetry and composition in spherical quantum dots and elongated quantum rods made of CdS and CdSe. The ground state crossovers which ... -
Hole relaxation bottlenecks in CdSe/CdTe/CdSe lateral heterostructures lead to bicolor emission
American Chemical Society (2024-06-17)Concentric lateral CdSe/CdTe/CdSe heterostructures show bicolor photoluminescence from both a red charge transfer band of the CdSe/CdTe interface and a green fluorescence from CdSe. This work uses visible and near-infrared ... -
Hole spin mixing in InAs Quantum Dot Molecules
American Physical Society (2010)The spin state of holes confined in single InAs quantum dots have recently emerged as a promising system for the storage or manipulation of quantum information. These holes are often assumed to have no mixing between ... -
Hole spin relaxation in InAS/GaAs quantum dot molecules
IOP Publishing Ltd (2015-09)We calculate the spin–orbit induced hole spin relaxation between Zeeman sublevels of vertically stacked InAs quantum dots. The widely used Luttinger–Kohn Hamiltonian, which considers coupling of heavy- and light-holes, ... -
