A Tunable Anomalous Hall Effect in a Non-Ferromagnetic System
J. Cumings, L. S. Moore, H. T. Chou +4
We measure the low-field Hall resistivity of a magnetically-doped two-dimensional electron gas as a function of temperature and electrically-gated carrier density. Comparing these…
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…
Effects of strain, electric, and magnetic fields on lateral electron spin transport in semiconductor epilayers
M. Hruska, S. Kos, S. A. Crooker +2
We construct a spin-drift-diffusion model to describe spin-polarized electron transport in zincblende semiconductors in the presence of magnetic fields, electric fields, and off-di…
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…
Excitons in Carbon Nanotubes with Broken Time-Reversal Symmetry
S. Zaric, G. N. Ostojic, J. Shaver +10
Near-infrared magneto-optical spectroscopy of single-walled carbon nanotubes reveals two absorption peaks with an equal strength at high magnetic fields ( 55 T). We show that th…
Definitive observation of the dark triplet ground state of charged excitons in high magnetic fields
G. V. Astakhov, D. R. Yakovlev, V. V. Rudenkov +8
The ground state of negatively charged excitons (trions) in high magnetic fields is shown to be a dark triplet state, confirming long-standing theoretical predictions. Photolumines…
