Abstract

The use of graphene for 'conducting phase + glass’ thick films that are screen-printed on the alumina ceramic substrate and then heat-treated in a vacuum furnace has been studied. Quantitative microanalysis of carbon and glass elements has been carried out and the microstructure and electrophysical properties of the films have been examined. The film surface layer shows an increased carbon content, the current–voltage diagram is linear, which indicates that Ohm’s law is obeyed, and resistivity decreases with increasing temperature. The temperature coefficient of resistivity is negative. It has been concluded that graphene can be used as a conducting phase in thick films.
