Abstract

We present results of our calculations on the optical properties of the freestanding (2,2) singled-walled boron nitride nanotube (SWBNNT) using the density functional theory (DFT) and random phase approximation (RPA). Previous study shows that freestanding (2,2) SWBNNT holds a narrow band gap of 3.01 eV. Then, our optical calculations exhibit that freestanding (2,2) SWBNNT generates the main absorption peaks are in the ultraviolet (UV) energy ranges. Furthermore, the freestanding (2,2) SWBNNT can absorb light at longer wavelengths. It starts from the visible light until the ultraviolet type C (UVC). These findings offer a chance that material can be applied as a photocatalyst. © 2020. Asian Research Publishing Network (ARPN). All Rights Reserved.
