| Nanoribbons, due to their unique quantum confinement effects and surface effects, have high potential for applications in nanoelectronics and spintronics. This study investigates the electronic properties of zigzag-edged MXene nanoribbons, focusing on functionalized MXenes of the form M2XT2, where M = Ti, Zr, Sc, X = C, and T = O, F. Using density functional theory (DFT), we analyze nanoribbons with varying sizes (n = 9 to 15) and edge configurations. Our results reveal that except for 9-ZNR, 12-ZNR, and 15-ZNR, all other zigzag-edged MXene nanoribbons exhibit metallic properties, with the presence of X = C in the edge configurations being a distinguishing factor. For the semiconducting nanoribbons, the band gaps decrease uniformly with increasing width, which aligns with quantum confinement effects. We also observe that the conduction and valence bands are primarily influenced by the d-orbitals of the transition metals (Ti, Zr, Sc) and the p-orbitals of the functional groups (C, O, F), with specific band structures indicating indirect band gaps for semiconductor behavior. Our findings suggest that the electronic properties of these nanoribbons are significantly affected by their size, edge configuration, and functionalization, providing valuable insights for potential applications in electronic and optoelectronic devices. | ||
