Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis
Atanu Patra, Paul Konrad, Andreas Sperlich +6
Negatively charged boron vacancies () in hexagonal boron nitride (hBN) are emerging as promising solid-state spin qubits due to their optical accessibility, structu…
Intermediate Excited State Relaxation Dynamics of Boron Vacancy Spin Defects in Hexagonal Boron Nitride
Paul Konrad, Mehran Kianinia, Lesley Spencer +5
Optically addressable spin defects in hexagonal boron nitride offer promising potential for 2D quantum sensing, though excited-state dynamics remain poorly understood. In particula…
Photoinduced Spin Centers in Photocatalytic Metal-Organic Framework UiO-66
Anastasiia Kultaeva, Timur Biktagirov, Andreas Sperlich +4
Metal-Organic frameworks (MOFs) are promising candidates for advanced photocatalytically active materials. These porous crystalline compounds have large active surface areas and st…
Onset of Spin Entanglement in Doped Carbon Nanotubes Studied by EPR
Andreas Sperlich, Klaus H. Eckstein, Florian Oberndorfer +5
Nanoscale semiconductors with isolated spin impurities have been touted as promising materials for their potential use at the intersection of quantum, spin, and information technol…
Semiconductor Room-Temperature Maser
Andreas Gottscholl, Maximilian Wagenhöfer, Valentin Baianov +3
We report the first demonstration of a semiconductor maser based on silicon vacancies (VSi) in 4H-silicon carbide (SiC). Using an active feedback loop, we enhance the resonator's q…
Ultralong-term high-density data storage with atomic defects in SiC
M. Hollenbach, C. Kasper, D. Erb +9
There is an urgent need to increase the global data storage capacity, as current approaches lag behind the exponential growth of data generation driven by the Internet, social medi…
