While synthesis procedures for nanotubes based on layered materials other than graphene are well-known [1, 2, 3], their transport properties are so far largely unexplored [4]. Here, we introduce transition metal dichalcogenide (TMDC) nanotubes as a new material platform for transport spectroscopy. We present results on optimized nanotube synthesis, first device fabrication, and electrical characterization. MoS₂ and WS₂ nanotubes are synthesized using a chemical transport reaction. Optimized growth parameters lead to thin nanotubes with diameters down to 7nm, lengths up to several millimeters, and an extremely low number of structural defects. Field effect devices based on individual nanotubes are characterized in low temperature transport measurements.
