WebThe current was adjusted to different power levels, and the temperature profile of the HrGOT at each power level was recorded using a FLIR A325sc infrared camera with a close-up lens.The temperature at the heat sink is taken as Ts, and the highest temperature in the middle of the sample is taken as Tm. WebLarge, temperature-independent mobilities approach those in exfoliated graphene placed on silicon oxide, but lower than mobilities in suspended graphene produced by the drawing method. Even without transfer, graphene on SiC exhibits massless Dirac fermions.
