摘要：

Temperature dependence of field-emission (FE) characteristics was investigated for the spray-coated few-layer graphene (FLG) film. The results show that the turn-on field and work function both decrease with increasing temperature from room temperature to 623 K. The possible physical mechanism was proposed based on that the FLG sheets with different stacking orders are nonzero or zero band gap semiconductors. (C) 2011 American Institute of Physics.
