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…
Optical lineshapes of the C-center in silicon from ab initio calculations: Interplay of localized modes and bulk phonons
Rokas Silkinis, Marek Maciaszek, Vytautas Žalandauskas +4
In this work, we present a first-principles density functional theory (DFT) computational investigation of the luminescence and absorption lineshapes associated with the neutral ca…
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…
Optical lineshapes for orbital singlet to doublet transitions in a dynamical Jahn-Teller system: the NiV center in diamond
Rokas Silkinis, Vytautas Žalandauskas, Gergő Thiering +4
We apply density functional theory to investigate interactions between electronic and vibrational states in crystal defects with multi-mode dynamical Jahn-Teller (JT) systems. Our…
Blue quantum emitter in hexagonal boron nitride and carbon chain tetramer: proposition of identification
Marek Maciaszek, Lukas Razinkovas
Single photon emitters in hexagonal boron nitride offer a gateway to the future of quantum technologies, yet their identification remains challenging and subject to ongoing debate.…
