We report in situ Joule heating on suspended single-layer graphene in a transmission electron microscope (TEM). Thermally-driven degradation of pre-deposited nanoparticles on the membrane is monitored and used for local temperature estimation. By extrapolating the Joule heating power and temperature relation, we find that the suspended single-layer graphene has exceptional thermal stability up to at least 2600 K.
