摘要：
Two-dimensional complete stacking bilayer molybdenum disulfide (MoS2) crystals with several unconventional morphologies, including four-point star, hexagon, rhomboid, trapezoid, and pentagon, have been attained by employing the space-confined chemical vapor deposition approach. The morphology, structure, and fundamental features of as-produced domains are systematically characterized via utilizing optical microscopy, atomic force microscopy, and Raman/PL system, elucidating bilayer feature of various MoS2 flakes. The variation of such various bilayer MoS2 crystals is discussed based on the difference of growth rate between different sides.
