This advance in technology is due to the unique properties of epitaxial graphene on silicon carbide (SiC) which lifts the stringent requirements for quantum hall effect seen in conventional semiconductors. This paper presents the processes involved in fabriion
The robust 2D/2D heterojunction allows fast transfer of energetic electrons from SiC to RGO. Coining the vital role of RGO in facilitating CO 2 activation, the optimized SiC/RGO exhibits an electron‐transfer rate of 58.17 μmol h −1 g −1 towards CO 2 reduction, 2.7 times that of pure SiC (20.25 μmol h −1 g −1 ).

Fabriion and mechanical properties of Al-SiC-B4C metal matrix composite via powder metallurgy Joint Conference: International Conference on DIAMOND AND CARBON MATERIALS & GRAPHENE AND SEMICONDUCTORS July 17-18, 2017 Chicago, USA Saif
Friction stir processing (FSP) has emerged as a valuable technique in the surface metal matrix composite fabriion field. In this process, solid-state processing mostly avoids the formation of detrimental phases inside composites. Despite having a high specific strength, further extensive Al alloy appliions are limited due to their poor surface properties. A hybrid reinforcement approach
