The results show that after introducing DMSO, the performance of GFETs was significantly improved: the maximum drain current ID max, the maximum transconductance gm max, and the field-effect mobility increase by 2.5, 24, and 23 times, respectively. The mechanism for the performance enhancement by high- dielectric was analyzed by Raman spectroscopy and transport measurements, and both are consistent with each other.", }
