Interfacial charge-modulated carbon nanotube FET with a WS2 nanosheet sensing layer for room-temperature H2S detection
Hydrogen sulfide (H2S) leakage is a critical threat to industrial safety, environmental monitoring, and human health, yet low-power detection of low-concentration H2S at room temperature remains challenging because gas-adsorption-induced electrical signals are typically weak and susceptible to environmental interferenc...
