We report on successful fabrication of a series of sus-pended trapezoid graphene devices and observation of the thermal rectification phenomenon at low temperatures. The trapezoid graphene channel is patterned by electron beam lithography (EBL) followed by reactive ion etching (RIE). From the experimental results, we find that heat transport is strongly related to the heat injection length from the hot region to the graphene channel.
