摘要：
A novel ultra-sensitive Parity-Time symmetry based Graphene FET (PT-GFET) sensor is studied for gas concentration detection. The PT-GFET sensor effectively integrates the sensitivity of the PT symmetry around its Exceptional Point (EP) and the tunability of the GFET conductance. The change of GFET conductance with the gas concentration can be brought back to the EP of the PT-GFET by tuning the gate voltage on the GFET. Thus, the applied gate voltage indicates the gas concentration. The minimum detectable gas concentration has been derived and estimated based on the experimental data, which shows that PT-GFET sensors can detect gas concentration below 50 ppb.
