DOI: 10.1002/adma.202302705
Abstract: Noninvasive fluorescence (FL) imaging and high-performance photocatalytic therapy (PCT) are opposing optical properties that are difficult to combine in a single material system. Herein, we report a facile approach to introducing oxygen-related defects in carbon… read more here.

DOI: 10.1016/j.jcrysgro.2019.01.008
Abstract: Abstract Oxygen-related thermal donors generated generally form less effectively in multicrystalline than in Czochralski grown monocrystalline silicon. In addition to a lower interstitial oxygen concentration, carbon and extended crystallographic defects are possible candidates that can… read more here.

DOI: 10.35848/1882-0786/ad45ae
Abstract: We investigated the abundance, structures, energy levels, and spin states of oxygen-related defects in 4H-SiC on the basis of first-principles calculations. We applied a hybrid functional in the overall calculations, which gives reliable defect properties,… read more here.
