Abstract

The effects of extrinsic and intrinsic performances on the electrical property of few-layer graphene (FLG) are investigated. This study uses the ultraviolet irradiation technique to tune the electrical parameters of FLG for analyzing the extrinsic/intrinsic contribution to the electrical conductivity. A correlation between the temperature-dependent electrical properties, phonon and impurity scatterings, and thermal activation of charge carriers is identified. The observed temperature evolution of resistivity is understood from the competition among the effects of phonon and impurity scatterings and thermal activation of charge carriers. It is important to identify the carrier transport behavior for enhancing the FLG-based device performance.
