title = "Impact of silver nanoparticles on current transport in CVD Mono-layer Graphene/Si Junctions",
abstract = "This work presents the impact and interaction of silver nanoparticles (Ag NPs) on chemical vapor deposited (CVD) mono-layer graphene-Si junctions. The vertical and lateral/surface current transport properties for different Si-substrate samples (varying top Si surface treatment) are studied using conductive mode Atomic Force Microscope (C-AFM) and micro-probe station. The presence of NPs modulates the surface conductivity of the graphene layers. Additionally, the presence of a thin 2nm Al2O3 Atomic Layer Deposition (ALD) between the Si substrate and CVD graphene film enhances the transport across the junction by providing an effective lower contact resistance for the nano-SB junction. The results indicate that the presence of cluster of NPs lowers the junction current. Whereas a single NP (nano-probe) contact enhances the localized electric field thus increasing the reverse bias tunneling current. The combination of NPs sizes and types will allow for custom tuning of the nano-SB properties for the desired applications.",
