2D transition metal dichalcogenides (TMDs) have attracted much attention for their gas sensing applications due to their superior responsivity at typical room temperature. However, low power consumption and reliable selectivity are the two main requirements for gas sensors to be applicable in future electronic devices. Herein, a p‐type (WSe2/WS2) and n‐type (MoS2/WSe2) photovoltaic self‐powered gas...
In article number 2003360, Woo‐Hee Kim, Jusang Park, Hyungjun Kim, and co‐workers demonstrate a photovoltaic self‐powered gas sensor using a two‐dimensional (2D) transition metal dichalcogenide (TMD) heterostructure for the first time. The p‐ (WSe2/WS2) and n‐type (MoS2/WSe2) gas sensors exhibit highly sensitive, selective gas sensing properties to NO2 and NH3 gas without external bias due to their...
