Molybdenum Disulfide/Double‐Wall Carbon Nanotube Mixed‐Dimensional Heterostructures

Mixed-dimensional heterostructures which combine materials with different dimensions have emerged to expand the scope and functionality of van der Waals heterostructures. Here, a direct synthesis method molybdenum disulfide/double-wall carbon nanotube (MoS2/DWCNT) mixed-dimensional by sulfurating molten salt, Na2MoO4, on substrate covered DWCNT film is reported. The synthesized are comprehensively characterized their stacking order confirmed be MoS2 under DWCNTs, although transferred first. Moreover, field-effect transistors based heterostructure fabricated for photodetection, an abnormal negative photoresponse discovered due strong carrier transfer in light incidence. MoS2/DWCNT results provide new approach applications
