UCR Today: Graphene Not All Good

In a first-of-its-kind study of how a material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobile in surface water and therefore likely to cause negative environmental impacts if spilled.

Graphene for metal-semiconductor Ohmic contacts - …

Abstract: One of the key components of modern device structures is the metal-semiconductor (MS) contact with low symmetric contact resistance. We report on a MS contact structure utilizing graphene insertion. In this strategy, graphene reduces or even eliminates in ideal conditions, the Fermi-level pinning at a MS junction.

Phys. Rev. Research 2, 043057 (2020) - Scattering …

Graphene sandwiched between semiconducting monolayers of ferromagnet Cr 2 Ge 2 Te 6 and transition-metal dichalcogenide WS 2 acquires both spin-orbit (SO) coupling, of valley-Zeeman and Rashba types, and exchange coupling. Using first principles combined with quantum transport calculations, we predict that such doubly proximitized graphene within van der Waals heterostructure …

Van der Waals Integrated Silicon/Graphene/AlGaN …

Silicon-based light emitting diodes (LED) are indispensable elements for the rapidly growing field of silicon compatible photonic integration platforms. In the present study, graphene has been utilized as an interfacial layer to realize a unique illumination mechanism for the silicon-based LEDs. We designed a Si/thick dielectric layer/graphene/AlGaN heterostructured LED via the van der Waals ...

Coatings | Free Full-Text | Roles of Graphene Additives …

The electrodeposition technique was used to fabricate graphene and Cr particle-reinforced Ni–Cr–graphene coatings. The Rietveld refinement was utilized to analyze the microstructure of Ni deposits in the coatings. The properties including micro-hardness and corrosion behaviors of the coatings were also tested. Results showed that the addition of graphene particles contributed to the ...
