DOI: 10.1002/cphc.202200575
Abstract: Abstract Single‐photon ionisation of enantiopure methyl p‐tolyl sulfoxide by circularly polarised light at 133 nm shows remarkably strong photoelectron circular dichroism (PECD), which has been measured in a velocity‐map‐imaging spectrometer. Both enantiomers were measured, each showing… read more here.

DOI: 10.1002/smll.202205229
Abstract: III-Nitride semiconductor-based quantum dots (QDs) play an essential role in solid-state quantum light sources because of their potential for room-temperature operation. However, undesired background emission from the surroundings deteriorates single-photon purity. Moreover, spectral diffusion causes… read more here.
