A hybridized graphene carrier highway for enhanced thermoelectric power generation

Abstract

The decoupling and enhancement of both Seebeck coefficient and electrical conductivity were achieved by constructing the c-axis preferentially oriented nanoscale Sb 2Te 3 film on monolayer graphene. The external graphene layer provided a highway for charge carriers, which were stored in the thicker binary telluride film, due to the extremely high mobility. © 2012 the Owner Societies.
