Graphen Layer Formation On A Carbon Based Substrate

Background:

Plastics are cheap, durable, light-weight and have a wide range of practical applications. Despite its universality, plastic materials suffer from low thermal conductivity that limits them from many other uses. Graphene has many remarkable properties, that in conjunction with other materials, can enhance their functionality and usage in various market segments. The graphene market is projected to reach $200M by 2026.

Brief Description:

UCR researchers have developed a novel system and method for forming graphene layers on a substrate. The system allows for direct growth of graphene on diamonds and low temperature growth of graphene using a carbon source. Due to the various novel features of the system, one can make the most of graphene’s excellent intrinsic thermal conductivity by substantially improving the radio frequency characteristics. Thermal conductivity can be strengthened by adjusting the size and alignment of the graphene flakes.
