Optical Visualization of Radiative Recombination at Partial Dislocations in GaAs
Todd Karin, Xiayu Linpeng, Ashish K. Rai +3
Individual dislocations in an ultra-pure GaAs epilayer are investigated with spatially and spectrally resolved photoluminescence imaging at 5~K. We find that some dislocations act…

Longitudinal spin-relaxation of donor-bound electrons in direct bandgap semiconductors
Todd Karin, Xiayu Linpeng, M. V. Durnev +6
We measure the donor-bound electron longitudinal spin-relaxation time () as a function of magnetic field () in three high-purity direct-bandgap semiconductors: GaAs, InP, a…

Giant permanent dipole moment of 2D excitons bound to a single stacking fault
Todd Karin, Xiayu Linpeng, M. M. Glazov +7
We investigate the magneto-optical properties of excitons bound to single stacking faults in high-purity GaAs. We find that the two-dimensional stacking fault potential binds an ex…
