Gapless linear band structure quantum electronic materials play important roles in quantum computing developments due to their novel superb electronic transport properties and two-dimensional (2D) gateable device possibility. However, the sensitive surface of quantum electronic materials easily reacted with ambient air molecules so as to change their intrinsic transport properties. We review a series of our works to show the importance of surface reactions in quantum electronic materials, such as graphene. By using different electronic transport facilities and in situ vacuum annealing methods, we are able to gently clean the absorbed air molecules on graphene so as to change the carrier densities and the electronic transport properties, which is a great improvement for 2D-quantum material-based quantum chips and computing devices.
