Properly piled up : Single‐layer 2D semiconducting nanomaterials of MoS 2 , WS 2 , TiS 2 , TaS 2 , ZrS 2 , and graphene were fabricated through an electrochemical lithiation process (see picture). The production of single‐layer MoS 2 was achieved in 92 % yield. A single‐layer MoS 2 ‐based thin‐film transistor was fabricated, which was used for sensing NO at a detection limit of 190 ppt.
