We present a first-principles investigation of electron transport in graphene contact with Au electrodes. Using destiny function theory and a non-equilibrium Green’s function approach, we obtain the best transmission spectrum and current-voltage profiles for Au-graphene-Au contacting device. For this device, the current exist an obvious increase in scattering region as rotating graphene at a low bias voltage. The maximum current (2.813?A) is found at 30 degree of rotating graphene sheet. As the bias increase, there is a negative differential conductance effect at rotating 120 degree. These results provide some potential applications in oscillator and transistor devices.
