Intrinsic structural defects and defect dominated transport in MoS 2 . (A) Bright-field transmission electron microscope (TEM) image (top) and its corresponding colored dark-field image (bottom) show irregularly shaped polycrystalline grains of MoS2. (B) Temperature-dependent conductivity of a few-layer MoS2 FET under various back gate voltages. The linear fits indicate 2-D variable-hopping transport in MoS2.
