Single Crystals of MoS2 Several Molecular Layers Thick

Key Points

• To isolate and characterize ultrathin single crystals of molybdenum disulfide (MoS2) that are only several molecular layers thick.
• Cleaved bulk molybdenum disulfide single crystals to isolate ultrathin crystalline sheets.
• Evaluated the structural integrity and thickness of the resulting few-layer crystal specimens.
• Successfully produced stable single crystals of MoS2 with thicknesses reduced to several molecular layers.
• Demonstrated that few-layer MoS2 flakes maintain ordered crystalline structures at near-atomic dimensions.
