benzenethiol

Exciting work by PhD student Alex Gee published in Nanotechnology detailing how to make “Nanoscale Junctions for Single Molecule Electronics Fabricated using Bilayer Nanoimprint Lithography combined with Feedback Controlled Electromigration“.

The paper then uses the approach to make  a high conductance molecular bridge formed with 2 benzenethiol molecules.

New publication in IEEE Transaction on Nanotechnology. This work compares the different switching mechanisms in devices made with the same materials but having different nanostructure geometries. The article is entitled “Nanorods vs Nanoparticles: A Comparison Study of Au/ZnO-PMMA/Au Non-volatile Memory Devices showing the importance of Nanostructure Geometry on Conduction Mechanisms and Switching Properties

(see DOI: 10.1109/TNANO.2019.2949759)

GrapheneOx_Dev

New publication in Carbon (IF 7.5) reporting on the first optically tuneable memristor device made with graphene oxide. The work importantly demonstrates both reversible and irreversible optical switching effects depending on whether the light is in the visible or UV electromagnetic spectrum. (read article here )

filamentary_deviceOur latest work on the development of Optical Memristors for Light-Tuneable Synaptic Learning has been published in Advanced Electronic Materials. In this work we demonstrate very large optical switching between two resistive memory states.

 (see DOI:10.1002/aelm.201900197)

label-free nanogap biosensor2Our recent work on the development of a label-free nanogap capacitive biosensor has been published in PCCP. In this work we take advantage of a very small distance between metal electrodes to eliminate electrode polarization effects that normally produce very large parasitic capacitance.

(see DOI:10.1039/C8CP05510F).
