Identification of carbon-related color centers in hBN by high-resolution ab initio photoluminescence modeling
Vytautas Žalandauskas, Marek Maciaszek, Marianne Etzelmüller Bathen +3
Identification of optically active defects in hexagonal boron nitride (hBN) remains challenging because different defect candidates can produce similar calculated photoluminescence…
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…
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…
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…
