A nanoscale conductor/semiconductor/insulator device includes a substrate with a lattice and a plurality of nanotubes in crystallographic alignment with the lattice at an interface between the plurality of nanotubes and the substrate. Another such device includes a substrate, meandering tracks in the substrate and a plurality of nanotubes adhering to cut-atomic-step edges of the meandering tracks. Methods of making the nanoscale conductor/semiconductor/insulator devices are also disclosed.

Ordered nanotubes on a two-dimensional substrate consisting of different material properties

The present invention relates to the presence of nanogaps across a metal dispersed over an atomically-thin material, such that the nanogap exposes the atomically-thin material. The resulting device offers an ultra-short gap with ballistic transport and demonstrated switching in the presence of a gate or dielectric material in close proximity to the channel.

Nanogaps on atomically thin materials as non-volatile read/writable memory devices

The present invention relates to atomically-thin channel materials with crystallographically uniform interfaces to atomically-thin commensurate graphene electrodes and/or nanoribbons separated by nanogaps that allow for nanoelectronics based on quantum transport effects and having significantly improved contact resistances.

Integrated multi-terminal devices consisting of carbon nanotube, few-layer graphene nanogaps and few-layer graphene nanoribbons having crystallographically controlled interfaces

A thermal and electrical conducting apparatus includes a few-layer graphene film having a thickness D where D&#x2266;1.5 nm and a plurality of carbon nanotubes crystallographically aligned with the few-layer graphene film.

Crystallographically-oriented carbon nanotubes grown on few-layer graphene films

Disclosed are devices comprising multiple nanogaps having a separation of less than about 5 nm. Also disclosed are methods for fabricating these devices.

Parallel fabrication of nanogaps and devices thereof

An electronic device includes a first electrode, a second electrode and a nanowire connected between the first and second electrodes to allow electric current flow. The nanowire is made from a conductive material exhibiting a variable resistance due to electromigration. The nanowire is repeatably switchable between two states. A voltage clamp operates through feedback control to maintain the voltage across the nanowire and prevent thermal runaway.
