Enhanced gas sensing response for 2D α-MoO3 layers: Thickness-dependent changes in defect concentration, surface oxygen adsorption, and metal-metal oxide contact

•Synthesis of α- MoO3 2D layers and thin films via pulsed laser deposition technique.•2D layers show high gas sensing performance towards NO2 as compared to the thin film.•p-type gas sensing behavior observed in 2D layers in contrast to n-type gas sensing behavior in thin film.•Sensor behavior is ex...
