... of the interaction between TM-doped graphene nanosheet and NO molecule. Design/methodology/approach A high performance of TM-doped graphene nanosheet as a gas sensor is demonstrated by modeling the material’s transport characteristics by means of the Langmuir adsorption and three-layered ONIOM/ density...

... ) Sensitivity is one of the principal characteristics of a gas sensor. When the sensor is exposed to a target gas, its physical structure or chemical properties are changed (Wang et al., 2010). The electronic transport details can be calculated in low-bias conductance by using the Green’s function...
