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…
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…
Theory of the divacancy in 4H-SiC: Impact of Jahn-Teller effect on optical properties
Vytautas Žalandauskas, Rokas Silkinis, Lasse Vines +2
Understanding the optical properties of color centers in silicon carbide is essential for their use in quantum technologies, such as single-photon emission and spin-based qubits. I…
Vibrational and vibronic structure of isolated point defects: the nitrogen-vacancy center in diamond
Lukas Razinkovas, Marcus W. Doherty, Neil B. Manson +2
We present a theoretical study of vibrational and vibronic properties of a point defect in the dilute limit by means of first-principles density functional theory calculations. As…
