摘要:

我们报告的第一次测量的热导率的悬浮单层石墨烯。使用非接触式光学技术进行测量。对于单层石墨烯,提取了在~ 4840至5300 W/mK范围内的热导率的近室温值。极高的热导率值表明石墨烯在热传导方面可以胜过碳纳米管。

英文摘要:

We report on the first measurement of the thermal conductivity of a suspended single layer graphene. The measurements were performed using a non-contact optical technique. The near room-temperature values of the thermal conductivity in the range ~ 4840 to 5300 W/mK were extracted for a single-layer graphene. The extremely high value of the thermal conductivity suggests that graphene can outperform carbon nanotubes in heat conduction.
