Copper telluride (Cu2Te) is theoretically a potential solid-state thermoelectric material with excellent thermoelectric performance. However, it has not achieved excellent thermoelectric performance in various copper chalcogenide-based research to data, and it is a materials with the potential to improve the performance. We suggest a promising strategy to effectively improve the thermoelectric performance of Cu2Te by introducing graphene sheets. A combination of thermoelectric properties reveals that graphene incorporation facilitates enhancing thermoelectric performance. The maximum thermoelectric ZT value of about 1.14 is achieved at 1000 K, 270% higher than for pristine Cu2Te. This strategy can provide insight that can extend copper chalcogenide-based high-performance thermoelectrics.
