- Abstract
Nanostructured bulk composites consisting of BiTe nanowires (NWs) with graphene particles are fabricated with different graphene content, and their thermoelectric properties were examined. As-prepared graphene materials were evenly distributed into the BiTe NW matrix, leading to the formation of the graphene/BiTe composite structures. The sintered composite with 0.5 wt% graphene content generated improved thermoelectric power factor of 688.9 μW/m K, compared to the BiTe NW sample without grapheme, because of the enhanced Seebeck coefficient of the composite originating from the decreased carrier concentration. Our synthesized graphene/BiTe NW hybrid composites are promising route to achieve high performance of thermoelectric materials.
