Energetic cost of measurements using quantum, coherent, and thermal light
Xiayu Linpeng, Léa Bresque, Maria Maffei +3
Quantum measurements are basic operations that play a critical role in the study and application of quantum information. We study how the use of quantum, coherent, and classical th…
Ensemble spin relaxation of shallow donor qubits in ZnO
Vasileios Niaouris, Mikhail V. Durnev, Xiayu Linpeng +6
We present an experimental and theoretical study of the longitudinal electron spin relaxation () of shallow donors in the direct band-gap semiconductor ZnO. is measured…
Optical spin control and coherence properties of acceptor bound holes in strained GaAs
Xiayu Linpeng, Todd Karin, Mikhail V. Durnev +5
Hole spins in semiconductors are a potential qubit alternative to electron spins. In nuclear-spin-rich host crystals like GaAs, the hyperfine interaction of hole spins with nuclei…
Layer-Resolved Magnetic Proximity Effect in van der Waals Heterostructures
Ding Zhong, Kyle L. Seyler, Xiayu Linpeng +8
Magnetic proximity effects are crucial ingredients for engineering spintronic, superconducting, and topological phenomena in heterostructures. Such effects are highly sensitive to…
Microscopic model of stacking-fault potential and exciton wave function in GaAs
Mikhail V. Durnev, Mikhail M. Glazov, Xiayu Linpeng +7
Two-dimensional stacking fault defects embedded in a bulk crystal can provide a homogeneous trapping potential for carriers and excitons. Here we utilize state-of-the-art structura…
Valley Manipulation by Optically Tuning the Magnetic Proximity Effect in WSe/CrI Heterostructures
Kyle L. Seyler, Ding Zhong, Bevin Huang +9
Monolayer valley semiconductors, such as tungsten diselenide (WSe), possess valley pseudospin degrees of freedom that are optically addressable but degenerate in energy. Liftin…
Coherence properties of shallow donor qubits in ZnO
Xiayu Linpeng, Maria L. K. Viitaniemi, Aswin Vishnuradhan +4
Defects in crystals are leading candidates for photon-based quantum technologies, but progress in developing practical devices critically depends on improving defect optical and sp…
Van der Waals Engineering of Ferromagnetic Semiconductor Heterostructures for Spin and Valleytronics
Ding Zhong, Kyle L. Seyler, Xiayu Linpeng +11
The integration of magnetic material with semiconductors has been fertile ground for fundamental science as well as of great practical interest toward the seamless integration of i…
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…
