Deep ultraviolet applications of mono-bilayer boron nitride nanoribbons: a first-principles study

Abstract

Abstract The optical properties of mono-bilayer boron nitride nanoribbons (BNNRs) on deep ultraviolet (DUV) region were calculated by adjusting the width, interlayer spacing and layer stacking. The band structure of monolayer BNNRs is sensitive to the width. DUV response also changes with the width, interlayer spacing and layer stacking in the mono-bilayer BNNRs. The N-N layer stacking can improve the reflectivity and absorption coefficient of DUV response. Therefore, the electronic properties and DUV response of mono-bilayer BNNRs can be tuned through changing the width, interlayer spacing and layer stacking. Our results show that BNNRs can be applied for DUV communication and DUV detectors, etc.
