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…
Superradiance of Spin Defects in Silicon Carbide for Maser Applications
Andreas Gottscholl, Maximilian Wagenhöfer, Manuel Klimmer +6
Masers as telecommunication amplifiers have been known for decades, yet their application is strongly limited due to extreme operating conditions requiring vacuum techniques and cr…
Electron-nuclear coherent coupling and nuclear spin readout through optically polarized VB- spin states in hBN
Fadis F. Murzakhanov, Georgy V. Mamin, Sergei B. Orlinskii +8
Coherent coupling of defect spins with surrounding nuclei along with the endowment to read out the latter, are basic requirements for an application in quantum technologies. We sho…
Long-Lived Spin-Polarized Intermolecular Exciplex States in Thermally Activated Delayed Fluorescence-Based Organic Light-Emitting Diodes
Sebastian Weissenseel, Andreas Gottscholl, Rebecca Bönnighausen +2
Spin-spin interactions in organic light-emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) are pivotal because radiative recombination is largely dete…
Coupling spin defects in hexagonal boron nitride to monolithic bullseye cavities
Johannes E. Fröch, Lesley Spencer, Mehran Kianinia +6
Color centers in hexagonal boron nitride (hBN) are becoming an increasingly important building block for quantum photonic applications. Herein, we demonstrate the efficient couplin…
Sub-nanoscale Temperature, Magnetic Field and Pressure sensing with Spin Centers in 2D hexagonal Boron Nitride
Andreas Gottscholl, Matthias Diez, Victor Soltamov +6
Spin defects in solid-state materials are strong candidate systems for quantum information technology and sensing applications. Here we explore in details the recently discovered n…
Room Temperature Coherent Control of Spin Defects in hexagonal Boron Nitride
Andreas Gottscholl, Matthias Diez, Victor Soltamov +6
Optically active defects in solids with accessible spin states are promising candidates for solid state quantum information and sensing applications. To employ these defects as qua…
Identifying Carbon as the Source of Visible Single Photon Emission from Hexagonal Boron Nitride
Noah Mendelson, Dipankar Chugh, Jeffrey R. Reimers +14
Single photon emitters (SPEs) in hexagonal boron nitride (hBN) have garnered significant attention over the last few years due to their superior optical properties. However, despit…
Room Temperature Initialisation and Readout of Intrinsic Spin Defects in a Van der Waals Crystal
Andreas Gottscholl, Mehran Kianinia, Victor Soltamov +7
Optically addressable spins in widebandgap semiconductors have become one of the most prominent platforms for exploring fundamental quantum phenomena. While several candidates in 3…
