▎ 摘　　要

We report the pressure dependent heat transfer at a multilayer graphene and gas interface. We find the resistance of a heated graphene device is changed due to convective heat transfer between a multilayer graphene and gas interface in gaseous environments. The pressure dependent convective heat transfer also shows differentiability for the gas species. Our findings suggest that such graphene based electrothermal microelectronics can be used for Pirani gauges and gas sensors. (C) 2016 Elsevier B.V. All rights reserved.
