Impact of strain on electron-phonon coupling of quantum emitters
Vytautas Žalandauskas, Rokas Silkinis, Lukas Razinkovas +6
Defects in semiconductors acting as optically active spin qubits are intriguing objects of fundamental study and future technological developments. These defect-based color centers…
Optical Stability and Photophysics of NV Centers in Diamond up to 120 GPa
Kin On Ho, Cassandra Dailledouze, Vytautas Žalandauskas +9
The nitrogen vacancy (NV) center has emerged as a powerful quantum sensor in high-pressure research, with the observation of optically detected magnetic resonance at megabar pressu…
Unraveling the electronic structure of silicon vacancy centers in 4H-SiC
Ali Tayefeh Younesi, Minh Tuan Luu, Christopher Linderälv +7
Point defects in silicon carbide (SiC), particularly the negatively-charged silicon vacancy () in 4H-SiC, are leading candidates for scalable quantum technolog…
Charge state equilibration of nitrogen-vacancy center ensembles in diamond: The role of electron tunneling
Audrius Alkauskas, Chris G. Van de Walle, Lukas Razinkovas +1
The charge state stability of nitrogen-vacancy (NV) centers critically affects their application as quantum sensors and qubits. Understanding charge state conversion and equilibrat…
Magneto-optical properties of Group-IV--vacancy centers in diamond upon hydrostatic pressure
Meysam Mohseni, Lukas Razinkovas, Vytautas Žalandauskas +2
In recent years, the negatively charged group-IV--vacancy defects in diamond, labeled as G4V(-) or G4V centers, have attracted significant attention in quantum information processi…
Characterization of Chromium Impurities in -GaO
Mark E. Turiansky, Sai Mu, Lukas Razinkovas +8
Chromium is a common transition-metal impurity that is easily incorporated during crystal growth. It is perhaps best known for giving rise to the 694.3 nm (1.786 eV) emission in Cr…
