Abstract(in English) | We report on experimental observation of temperature characteristics of a dual gate graphene field effect transisor (DG-GFET). We fabricated the device made of high-quality epitaxial graphene (EG) grown by thermal decomposition of a SiC substrate. And a SiN gate insulator was deposited more thickly than before to prevent the gate leakage current. We measured its I-V characteristics for both gates at different temperatures. We observed improved transconductance and carrier momentum relaxation time at lower temperatures reflecting the improved carrier transport property. |
