Engineering Physics Annotation << Back THE EPITAXIAL GRAPHENE – A PROMISING MATERIAL FOR A NEW CHEMICAL SENSOR TECHNOLOGY Z.Z. ALISULTANOV, E.Kh. ISRAPOV Within framework Davydov model, we investigated the thermoelectric transport (dc and ac conductivities) in epitaxial graphene formed on the semiconductor. We use the approach based on the Kubo formula for conductivity and differential thermopower. We shown that near band gap edges the conductivity changes as stepwise. We shown that near band gap edges the thermopower increases more than in four times. Using this results, we proposed a scheme of new chemical sensors. Key words: graphene, conductivity, Kubo formula, Green functions. Contacts: E-mail: zaur0102@gmail.com Pp. 48-52.
