Two-dimensional double-kagome-lattice nitrogene: a direct band gap semiconductor with nontrivial corner state
Wenzhang Li, Qin He, Xiao-Ping Li +2
Based on first-principles calculations, we predict that nitrogen atoms can assemble into a single-layer double kagome lattice (DKL), which possesses the characteristics of an intri…
