| 英文摘要 | Exploring stable two-dimensional materials with appropriate band gaps and high carrier mobility is highly desirable due to the potential applications in optoelectronic devices. here, the electronic structures of phosphorene on a au(111) substrate are investigated by scanning tunneling spectroscopy, angle-resolved photo emission spectroscopy (arpes), and density functional theory (dft) calculations. the substrate -induced phosphorene superstructure gives a superlattice potential, leading to a strong band folding effect of the sp band of au(111) on the band structure. the band gap could be clearly identified in the arpes results after examining the folded sp band. the value of the energy gap (similar to 1.1 ev) and the high charge carrier mobility comparable to that of black phosphorus, which is engineered by the tensile strain, are revealed by the combination of arpes results and dft calculations. furthermore, the phosphorene layer on the au(111) surface displays high surface inertness, leading to the absence of multilayer phosphorene. all these results suggest that the phosphorene on au(111) could be a promising candidate, not only for fundamental research but also for nanoelectronic and optoelectronic applications. |
