    abstract = {The high surface-to-volume ratio and flatness of
mechanically exfoliated van der Waals (vdW) layered materials
make them an ideal platform to investigate the Langmuir
absorption model. In this work, we fabricated field effect transistor
gas sensors, based on a variety of mechanically exfoliated vdW
materials, and investigated their electrical field-dependent gas
sensing properties. The good agreement between the experimentally
extracted intrinsic parameters, such as equilibrium constant
and adsorption energy, and theoretically predicted values suggests
validity of the Langmuir absorption model for vdW materials.
Moreover, we show that the device sensing behavior depends crucially on the availability of carriers, and giant sensitivities and strong
selectivity can be achieved at the sensitivity singularity. Finally, we demonstrate that such features provide a fingerprint for different
gases to quickly detect and differentiate between low concentrations of mixed hazardous gases using sensor arrays.},
