چکیده

The search for new materials is a very intense task in many technological areas. In 2015, variant of graphene was proposed, the pentagraphene, which followed by propose pentagonal boron nitride structure called penta-BN2. Based on these structures, we investigated electronic, magnetic, and optical properties penta-BN2 nanoribbons (p-BNNRs) considering four different kinds edges, carefully closing valence shells with H atoms to prevent dangling bonds. To achieve this goal, used first-principles calculations density functional theory framework. Our findings showed that p-BNNRs have rich magneto-electronic behavior, varying from semiconductor half-metal. We obtained they are ferrimagnetic, having an intrinsic magnetism, allow potential applications spintronic or spinwaves. From absorption point view, mainly absorb at ultraviolet region spectrum, especially UV-B region, could indicate application as UV filter.
