▎ 摘　　要

NOVELTY - A thermoelectric material comprises silicon-doped graphene layer formed by substituting a portion of carbon atoms of graphene by silicon atoms. USE - Thermoelectric material (claimed). ADVANTAGE - The thermoelectric material has high thermal performance index of more than 2. The thermal conductivity of the thermoelectric material can be reduced without changing electroconductivity and Seebeck coefficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of thermoelectric material.
