摘要

我们提出了超快泵浦探针测量，显示了石墨烯-六方氮化硼(hBN)异质结构中载流子的快速弛豫，这是由于石墨烯-六方氮化硼界面的高界面热传导。这保证了hBN作为高功率石墨烯器件的衬底的使用。

Ultrafast phonon dynamics in graphene-hBN structures

We present ultrafast pump-probe measurements that show fast relaxation of carriers in graphene-hexagonal Boron Nitride (hBN) heterostructures due to the high interfacial thermal conductance of the graphene-hBN interface. This warrants the use of hBN as a substrate for high powered graphene devices.
