Single atom graphene nanogap
Chemists at Leiden University have developed a method yielding a device separating two single carbon atoms from two individual conducting graphene layers.
The invention enables the fabrication of a graphene nanogap using a simple methodology. It has been impossible till now to fabricate a graphene nanogap.
The next stage of improvement includes (i) to define the (bio)chemical sensitivity of the device, (ii) chemical edge passivation and determination of the utility of the device as a spectroscope for graphene (and other 2D crystal edge characterization), (iii) to attempt the translocation and detection of individual (bio)(macro)molecules, and (iv) to design the micro/nanofluidic platform (for ‘controllably’ delivery of a single biomolecule to the point contact; for sequencing or characterization of molecules).
- Single atomic contact
- Basal plane protected (no need for extra sandwich insulating layers and hence no parasitic tunneling signal)
- No need for electron microscopy or lithographic equipment
- Mechanically robust, scalable formation
- New tunneling spectroscopes to characterise atomic contacts between two carbon atoms
- Study nanoconfined media such as gas, liquids, solid
- Detection of molecules in motion
- Sequencing molecules
- Characterization of polymers
- Study electrical transport through single (organic, bio-organic) molecules
- 3D Proof of concept (prototype)
- Fabrication process of the gap is validated
