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…
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.…
Thermodynamics of carbon point defects in hexagonal boron nitride
Marek Maciaszek, Lukas Razinkovas, Audrius Alkauskas
We present a first-principles computational study of the thermodynamics of carbon defects in hexagonal boron nitride (hBN). The defects considered are carbon monomers, dimers, trim…
Photoionization of negatively charged NV centers in diamond: theory and ab initio calculations
Lukas Razinkovas, Marek Maciaszek, Friedemann Reinhard +2
We present ab-initio calculations of photoionization thresholds and cross sections of the negatively charged nitrogen-vacancy (NV) center in diamond from the ground and…
Carbon dimer defect as a source of the 4.1 eV luminescence in hexagonal boron nitride
Mazena Mackoit-Sinkeviciene, Marek Maciaszek, Chris G. Van de Walle +1
We propose that the carbon dimer defect in hexagonal boron nitride gives rise to the ubiquitous narrow luminescence band with a zero-phonon line of 4.08 eV (usually labeled the 4.1…
