  • Modifying or functionalizing transition metal dichalcogenides (TMDs) allows their properties to be altered and controlled. Now, non-defect-mediated covalent functionalization of single-layer semiconducting TMDs such as MoS2, WS2 and MoSe2 has been demonstrated by reacting them with organohalides, utilizing the excess charge in the 1T metallic phase.

  • Non-optimal electrical contacts can significantly limit the performance of MoS2-based thin-film transistors. Transformation of semiconducting MoS2 into its metallic phase is now shown as a viable strategy to decrease the metal–MoS2 contact resistance.

  • Transition metal dichalcogenides are promising hydrogen evolution catalysts however they can require expensive processing steps to enhance their activity. Here, the authors report a one-step activation step in which room temperature hydrazine treatment results in much enhanced electrocatalytic performance.
