Evolution of carbon color centers in pristine hexagonal boron nitride by electric field
Seungmin ParkKyung Hee University, Seoul, Republic of Korea _______________________________________ Hexagonal boron nitride (hBN) is a unique two-dimensional van der Waals material with a wide bandgap of 6.2 eV, optical transparency, and stability under ambient conditions and high temperatures. Due to its wide bandgap, color centers at various wavelengths can be created within hBN, which have…

Combined Photoluminescence and Conductance Mapping of Color Centers in Hexagonal Boron-Nitride
Holland FrielingCalifornia Institute of Technology, Pasadena, California, USA _______________________________________ We report an analysis correlating photoluminescence and conductance of color centers in hexagonal boron-nitride (hBN). We first characterize these emitters using photoluminescence spectroscopy to determine the wavelength, photon purity, and relative location of the emitter. To probe conductance, we perform conductive atomic force microscopy mapping of…

UV Electroluminescence from Carbon Incorporated h-BN grown by MOCVD
Semi ImPohang University of Science and Technology – Pohang, Republic of Korea_______________________________________ Hexagonal boron nitride (h-BN) has emerged as a promising host material for optically active defects, exhibiting stable single-photon emission at room-temperature, high quantum efficiency, and exceptional photostability under extreme conditions. In particular, carbon-related defects in h-BN have recently attracted substantial interest due to…
