2. 1. Graphene Heat Spreaders for Electronics Thermal Management Applications

   Author : Yong Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; test platform; heat spreader.; transfer; Graphene; thermal management;

   Abstract : Graphene shows great potential for applications in electronics due to its outstanding physical properties such as extremely high electron mobility, high thermal conductivity, high Young’s modulus and very high surface-to-volume ratio. Among these attractive properties, the high intrinsic thermal conductivity is a critical advantage for the application of graphene in electronics to alleviate heat dissipation problems. READ MORE
