Bond reconstruction and vacancy clustering in monolayer silicon carbide from first principles
Péter Udvarhelyi
Bond reconstruction in vacancy-related structures affects their formation energies, symmetries, and electronic and optical properties. Using density functional theory, we investiga…
First-principles insights into the atomic structure of carbon-nitrogen-oxygen complex color centers in silicon
Péter Udvarhelyi
Spin-active color centers are the basis of solid-state defect systems utilized in quantum technologies. Although silicon is an emerging host material for quantum defects, there is…
Solid state defect emitters with no electrical activity
Pei Li, Song Li, Péter Udvarhelyi +2
Point defects may introduce defect levels into the fundamental band gap of the host semiconductors that alter the electrical properties of the material. As a consequence, the in-ga…
Giant shift upon strain on the fluorescence spectrum of VN color centers in -BN
Song Li, Jyh-Pin Chou, Alice Hu +5
We study the effect of strain on the physical properties of the nitrogen antisite-vacancy pair in hexagonal boron nitride (-BN), a color center that may be employed as a quantum…
\emph{Ab initio} theory of defect as quantum memory in diamond
Péter Udvarhelyi, Gergő Thiering, Elisa Londero +1
defect in diamond is characterized by means of \emph{ab initio} methods relying on density functional theory calculated parameters of a Hubbard model Hamilto…
