Lateral force microscopy (LFM) is used to probe the nanoscale elastic and frictional characteristics of molybdenum disulfide (MoS2). We find that MoS2 edges are effectively flexed over a region of about 10 nm when scanned with sharp single asperity L

Carbon nanotubes, few-layer graphene, and etch tracks exposing insulating SiO2 regions are integrated into nanoscale systems with precise crystallographic orientations. These integrated systems consist of nanotubes grown across nanogap etch tracks an

The catalytic activity of nanoparticles to form either crystallographically oriented etch tracks or carbon nanotubes on top of few-layer graphene is tuned through the application of a methane feedstock gas. The catalytic activity for these two proces

We demonstrate a technique for simultaneously fabricating arrays of electromigrated nanogaps using a single-ramp feedback-controlled voltage clamp. The parallel formation is achieved by controlling the applied bias with a voltage clamp directly adjac

Frictional, adhesive, and elastic characteristics of graphene edges are determined through lateral force microscopy. Measurements reveal a significant local frictional increase at exposed graphene edges, whereas a single overlapping layer of graphene

Carbon nanotubes are grown on few-layer graphene films using chemical vapor deposition without a carbon feedstock gas. We find that the nanotubes show a striking alignment to specific crystal orientations of the few-layer graphene films. The nanotube

Memristors have recently generated significant interest due to their potential use in nanoscale logic and memory devices. Of the four passive circuit elements, the memristor (a two-terminal hysteretic switch) has so far proved hard to fabricate out o

The effects of encapsulating graphene with poly(methyl methacrylate) (PMMA) polymer are determined through in situ electrical transport measurements. After regenerating graphene devices in dry-nitrogen environments, PMMA is applied to their surfaces.
