Submission Title

Effect of Electrolyte Concentration on Capacitance and Mobility of Graphene

Location

Jereld R. Nicholson Library: Grand Avenue

Subject Area

Physics/Applied Physics

Description

The use of Graphene Field Effect Transistors (Gra-FETs) as a biosensor is increasingly being used to study biological phenomena, due to the sensitivity and low reactivity of Gra-FETs with the sample. To further improve sensitivity in biological environments, we examined how different salt concentrations affect the mobility and capacitance of the graphene. Samples were also measured after an annealing process. We report on these correlations and speculate on methods to improve future detectors.
