▎ 摘　　要

We study the Josephson current in p wave pairing superconductor-normal metal-superconductor (SNS) graphene junctions at the finite temperature using the Dirac Bogoliubov-de Gennes (DBdG) formalism. It is found that the energy levels of the Andreev bound states and the Josephson current depend on the p wave pairing symmetry. The position of the maximum current is shifted to the left by increasing the temperature and the dc Josephson current shows a simple sinusoidal dependence on the phase in the p, wave symmetry SNS graphene junction at higher temperatures. The Josephson current displays an oscillating decay as a function of the length L and the period of oscillation of the Josephson current does not change by increasing the temperature.
