Electrical Characterization and Modeling of a Gelatin/Graphene System

Advances in Condensed Matter Physics, 2015
A gelatin/graphene composite has been analyzed by means of current density-voltage and the electrical impedance measurements. The DC electrical behavior has been interpreted in terms of an equivalent Thévenin model taking into account the open circuit ...
