Long nuclear spin decay times controlled by optical pumping in individual quantum dots
M. N. Makhonin, A. I. Tartakovskii, I. Drouzas +8
Nuclear polarization dynamics are measured in the nuclear spin bi-stability regime in a single optically pumped InGaAs/GaAs quantum dot. The controlling role of nuclear spin diffus…
Power Dependence of the Photocurrent Lineshape in a Semiconductor Quantum Dot
A. Russell, Vladimir I. Fal'ko
We propose a kinetic theory to describe the power dependence, , of the photocurrent (PC) lineshape in optically pumped quantum dots at low temperatures, in both zero and…
Bistability of optically-induced nuclear spin orientation in quantum dots
A. Russell, Vladimir I. Fal'ko, A. I. Tartakovskii +1
We demonstrate that bistability of the nuclear spin polarization in optically pumped semiconductor quantum dots is a general phenomenon possible in dots with a wide range of parame…
Visibility of graphene flakes on a dielectric substrate
D. S. L. Abergel, A. Russell, Vladimir I. Fal'ko
We model the optical visibility of monolayer and bilayer graphene deposited on a silicon/silicon oxide substrate or thermally annealed on the surface of silicon carbide. We conside…
Nuclear Spin Switch in Semiconductor Quantum Dots
A. I. Tartakovskii, T. Wright, A. Russell +10
We show that by illuminating an InGaAs/GaAs self-assembled quantum dot with circularly polarized light, the nuclei of atoms constituting the dot can be driven into a bistable regim…
