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…

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…
