Interfacial Charge

Self-transformation of Au clusters to Au nanocrystals (NCs) was achieved via thermal reduction and Au NCs integrated at the interface of CdSe QDs and graphene boost interfacial charge transfer efficiency.

Interfacial Charge

In Si–La0.7Sr0.3MnO3, the interfacial charge transfer driven strong localized antiferromagnetic and spin–orbit couplings favor positive magnetoresistance, which is suppressed by strong magnetic scattering induced by the top ZnO layer results in negative magnetoresistance.
