Real-time direct and diffraction X-ray imaging of irregular silicon wafer breakage

IUCrJ, 2016
Fracture and breakage of single crystals, particularly of silicon wafers, are multi-scale problems: the crack tip starts propagating on an atomic scale with the breaking of chemical bonds, forms crack fronts through the crystal on the micrometre scale ...

Time-resolved photoluminescence studies of perovskite chalcogenides

Faraday Discussions, 2022
The rates of excited-state decay through recombination processes determine the usefulness of a semiconductor for ambipolar devices. We find that recombination rates in chalcogenide perovskites are promising for continued progress towards solar cells.

BILIPROTEINS FROM THE BUTTERFLY Pieris brassicae STUDIED BY TIME-RESOLVED FLUORESCENCE AND COHERENT ANTI-STOKES RAMAN SPECTROSCOPY [PDF]

, 1988
The fluorescence decay time of the biliverdin IX7 chromophore present in biliproteins isolated from Pieris brassicae is determined to be 44 ± 3 ps. This value suggests a cyclic helical chromophore structure. The vibrational frequencies determined by CARS-
