“…The I-V curve is displayed in Figure 11b-f, where the gray lines in each figure correspond to the V W /WS 2 I-V curve. We can observe that the current starts to increase when a bias voltage of 1.8 V is applied [49]. Compared with the I-V curve of BC 6 N adsorption systems [33], the slope change of the I-V curve after V W /WS 2 adsorbed gas molecules is more obvious, and the conductivity change is more sensitive when detecting gas molecules.…”

The gas sensitivity of the W defect in WS2 (VW/WS2) to five toxic gases—HCHO, CH4, CH3HO, CH3OH, and CH3CH3—has been examined in this article. These five gases were adsorbed on the VW/WS2 surface, and the band, density of state (DOS), charge density difference (CDD), work function (W), current–voltage (I–V) characteristic, and sensitivity of adsorption systems were determined. Interestingly, for HCHO-VW/WS2, the energy level contribution of HCHO is closer to the Fermi level, the charge transfer (B) is the largest (0.104 e), the increase in W is more obvious than other adsorption systems, the slope of the I–V characteristic changes more obviously, and the calculated sensitivity is the highest. To sum up, VW/WS2 is more sensitive to HCHO. In conclusion, VW/WS2 has a great deal of promise for producing HCHO chemical sensors due to its high sensitivity and selectivity for HCHO, which can aid in the precise and efficient detection of toxic gases.
