제목 UV Photoluminescence from focused gallium-ion beam induced color centers in the atomically thin hexagonal boron nitride
초록  Hexagonal boron nitride (hBN), an insulator which gives excellent encapsulation of two-dimensional materials like graphene and transition metal dichalcogenides, has recently emerged as a promising material which exhibit polarized and high-brightness, room-temperature quantum emission from color centers. Many different methods have been performed to generate color centers in hBN such as thermal annealing, strain, and electron irradiation. In this work, we demonstrated 30keV gallium (Ga) ion beam irradiation on hexagonal boron nitride flake to create color centers. Through the focused Ga ion beam induced color centers in the hBN, we can observe various luminescence characteristics of hexagonal boron nitride in ultraviolet range. The result will show the potential of hexagonal boron nitride and development of hybrid quantum nanophotonic and optoelectronic devices based on the atomically thin hBN heterostructures.
