Gold-mediated exfoliation of ultralarge optoelectronically perfect monolayers with lateral dimensions up to ≈500 μm is reported. Electrical, optical, and X-ray photo-electron spectroscopy characterization show that the quality of the gold-exfoliated flakes is similar to that of tape-exfoliated flakes. Large-area flakes allow manufacturing of large-area mono-layer transition metal dichalcogenide electronics.
本文报道了一种通过金介导的方法实现超大面积（横向尺寸最大可达约 500μm）光电完美单层材料的剥离。通过对剥离得到的二维材料的电学、光学和 X 射线光电子能谱进行测试，结果表明其性能与胶带剥离法得到的二维材料相当。大面积单层二维材料的获得为制备大面积的过渡金属二卤族化合物电子器件提供了可能。
