Removing the orientational degeneracy of the TS defect in 4H–SiC by electric fields and strain
New Journal of Physics, 2021 We present a photoluminescence (PL) study of the recently discovered TS defect in 4H silicon carbide. It investigates the influence of static electric fields and local strain on the spectral properties by means of low temperature (≈4 K) ensemble ...

Single photon emitters based on Ni/Si related defects in single crystalline diamond
, 2010 We present investigations on single Ni/Si related color centers produced via ion implantation into single crystalline type IIa CVD diamond. Testing different ion dose combinations we show that there is an upper limit for both the Ni and the Si dose 10^12/

Colour centre generation in diamond for quantum technologies
Nanophotonics, 2019 Effective methods to generate colour centres in diamond and other wide band-gap materials are essential to the realisation of solid state quantum technologies based on such systems.

Formation of surface color centers at differently coordinated sites: MgO/Ag(1,1,19) [PDF]
, 2003 In order to find criteria for discrimination between surface color centers at terraces and steps, and bulk color centers, the characteristic losses of these centers have been investigated by electron energy loss spectroscopy on an epitaxial MgO film ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

The optical absorption of gamma irradiated and heat-treated natural quartz
Materials Research, 2005 Quartz with aluminum as impurity absorbs energy from ionizing radiation and modifies its color. Colorless quartz becomes smoky or dark smoky (morion quartz) when exposed to gamma rays.

Le Journal de Physique Colloques, 1973 Results of optical and EPR-experiments on color centers in additively and substractively colored SrCl2 single crystals are reported. In additively colored crystals F-centers could be obtained only after extremely rapid quenching. It was found that in crystals doped with O2- even with the very high quenching rate it was impossible to produce F-centers ...

Visible color-center laser in diamond [PDF]
Optics Letters, 1985 Laser action at 530 nm using H3 centers in diamond was observed with an efficiency of 13.5% at room temperature. Optical double-resonance experiments on N3 centers provided direct evidence for a (2)A metastable level. Its presence results in rapid decay of the excited (2)E state and low quantum efficiency as well as significant excited-state absorption

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
