Electronic thermal conduction in suspended graphene

• Electronic thermal conductivity, κe in suspended graphene is studied theoretically.
• Boltzmann equation directly solved for distribution function by the iteration method.
• Contribution from defects and in-plane, flexural, optical phonons is considered.
• κe dominated by flexural phonons (charged impurities) for T greater (less) than 75 K.
• Good fit to recent experimental data on κe in suspended graphene samples obtained.

The electronic thermal conductivity (ETC), κe, of suspended graphene (SG) is studied for 15

Electronic thermal conductivity of suspended graphene is studied following Boltzmann formalism by iteration and compared with recent data and low-temperature and high-energy relaxation rate approximations.Figure optionsDownload as PowerPoint slide
