Abstract
Abstract We conducted extensive density functional theory calculations within GGA + U approach to explore the geometry, electronic structure and optical properties of armchair and zigzag zinc oxide nanoribbons as a function of width. Our results show that single layered armchair ZnONRs are semiconductors, whereas the zigzag counterparts are metallic. However, the electronic energy gap in armchair configurations decreases considerably when the width of the ribbon increase. The first absorption peak of the armchair NRs is placed along the in-plane polarization and inside the visible spectral range; while it occurs at energies less than 1.2 eV for zigzag NRs. Moreover, the first absorption peak of both zigzag and armchair configurations is located in the ultraviolet region along the out-of-plane polarization. In addition, for all cases, the optical spectra are highly anisotropic along the in-plane and out-of-plane directions. These diverse electronic and optical properties might open ZnONR materials great possibility in future optoelectronic applications.
