Isotope substitution and polytype control for point defects identification: thecase of the ultraviolet color center in hexagonal boron nitride
Juliette PloLaboratoire Charles Coulomb, Montpellier, France _______________________________________ Identifying defects is an important goal in condensed matter physics. Once the natures of extrinsic and intrinsic defects are determined, processes to improve the quality and the purity of crystals can be optimized. Conversely, the controlled incorporation of dopants are basic tools for fabricating electronic and optoelectronic devices.Hexagonal…

X-ray Studies on Single-Photon Emission in hBN Stimulated by Ultrafast Laser Pulses
Yifeng CaoBrookhaven National Laboratory – Upton, New York, USA_______________________________________ Single-photon emission (SPE) is a phenomenon where individual photons are generated one at a time, serving as fundamental components for various strategic applications, including quantum cryptography, quantum sensing, and secure communications. In hexagonal boron nitride (hBN), defect-based single-photon emitters were discovered only recently, sparking considerable interest…
