Excitons in core-only, core-shell and core-crown CdSe nanoplatelets: interplay between in-plane electron-hole correlation, spatial and dielectric confinement
Fernando Rajadell, Juan I. Climente, Josep Planelles
Using semi-analytical models we calculate the energy, effective Bohr radius and radiative lifetime of neutral excitons confined in CdSe colloidal nanoplatelets (NPLs). The excitoni…
Electronic Origin of Linearly Polarized Emission in CdSe/CdS Dot-in-Rod Heterostructures
Josep Planelles, Fernando Rajadell, Juan I. Climente
Seeded CdSe/CdS nanorods exhibit intense polarized emission along the rod main axis. The degree of linear polarization cannot be explained by dielectric effects alone, an additiona…
Theory of electrons, holes and excitons in GaAs polytype quantum dots
Juan I. Climente, Carlos Segarra, Fernando Rajadell +1
Single and multi-band (Burt-Foreman) k.p Hamiltonians for GaAs crystal phase quantum dots are developed and used to assess ongoing experimental activity on the role of such factors…
Symmetry induced hole-spin mixing in quantum dot molecules
Josep Planelles, Fernando Rajadell, Juan I. Climente
We investigate theoretically the spin purity of single holes confined in vertically coupled GaAs/AlGaAs quantum dots (QDs) under longitudinal magnetic fields. A unique behavior is…
Anisotropy of spin-orbit induced electron spin relaxation in [001] and [111] grown GaAs quantum dots
C. Segarra, J. Planelles, J. I. Climente +1
We report a systematic study of the spin relaxation anisotropy between single electron Zeeman sublevels in cuboidal GaAs quantum dots (QDs). The QDs are subject to an in-plane magn…
Electron states in quantum rings with defects under axial or in-plane magnetic fields
J. Planelles, F. Rajadell, J. I. Climente
A comprehensive study of anisotropic quantum rings, QRs, subject to axial and in-plane magnetic field, both aligned and transverse to the anisotropy direction, is carried out. Elli…
