Abstract :
The multi-ion sensing properties of graphene based field effect transistor were investigated in this paper. Hydrogen and potassium ion sensitivities were measured. The believable detection concentration region was also defined. Finally, the distribution of time-dependence drift coefficient was also discussed. (keywords: graphene, ion sensitive field effect transistor, drift coefficient, potassium, and ion).
