SiGe quantum dots for fast hole spin Rabi oscillations
N. Ares, G. Katsaros, V. N. Golovach +5
We report on hole g-factor measurements in three terminal SiGe self-assembled quantum dot devices with a top gate electrode positioned very close to the nanostructure. Measurements…
Statistical Properties of Exciton Fine Structure Splittings and Polarization Angles in Quantum Dot Ensembles
Ming Gong, B. Hofer, E. Zallo +5
We propose an effective model to describe the statistical properties of exciton fine structure splitting (FSS) and polarization angle of quantum dot ensembles (QDEs). We derive the…
An artificial atom locked to natural atoms
N. Akopian, R. Trotta, E. Zallo +5
Single-photon sources that emit photons at the same energy play a key role in the emerging concepts of quantum information, such as entanglement swapping, quantum teleportation and…
Monolithic growth of ultra-thin Ge nanowires on Si(001)
Jianjun Zhang, Georgios Katsaros, Francesco Montalenti +8
Self-assembled Ge wires with a height of only 3 unit cells and a length of up to 2 micrometers were grown on Si(001) by means of a catalyst-free method based on molecular beam epit…
On the nature of tunable hole g-factors in quantum dots
N. Ares, V. N. Golovach, G. Katsaros +5
Electrically tunable g-factors in quantum dots are highly desirable for applications in quantum computing and spintronics. We report giant modulation of the hole g-factor in a SiGe…
Electronic and optical properties of quantum wells embedded in wrinkled nanomembranes
P. Cendula, S. Kiravittaya, O. G. Schmidt
The authors theoretically investigate quantum confinement and transition energies in quantum wells (QWs) asymmetrically positioned in wrinkled nanomembranes. Calculations reveal th…
