| 摘要 | Abstract A simple and effective air-annealing technique was developed to stably improve both the electrical conductivity and light transmission of pristine graphene. After the?graphene film was annealed in air at 250 °C for 80 min, the mobility and carrier concentration were both significantly enhanced, and the sheet resistance was greatly reduced with a decrease rate of ～33%. Meanwhile, the transparency was also improved by more than 3%. The mechanism is?carefully discussed. The reason might be that air-annealing conditions provide?a?suitable atmosphere to etch and remove amorphous carbons. More importantly, the enhanced transparent conductive properties of the air-annealed?graphene films were extraordinarily stable, and?remained almost unchanged?for?100 days. |
