What is Insight Into the Underlying Competitive Mechanism for the Shift of the Charge Neutrality Point in a Trilayer-graphene Field-effect Transistor about?

Design two regulating strategies of work temperature and vacuum pressure, and distinguish oxygen gas (O 2 ) and water molecular (H 2 O) contribution in a shift for the charge neutrality point of trilayer graphene. Establish a competitive doping model, and reveal three dominating factors of O 2 , H 2 O, and thermally activated electron stemming from underlying SiO 2 dielectric in competitive doping behavior. DFT calculations demonstrate the rationalization of the competitive doping mechanism model.
