Facilities

Wolfson Laboratory

The research programme of the Nanotechnology and Electronics Research Group is underpinned by the cleanroom-based Wolfson Laboratory for nanomaterials and devices.

The lab has extensive facilities for the design, fabrication and characterisation of graphene (and 2D related materials) devices and sensors (including bio-sensors), high-speed electronics, solar cells, brain tumour treating fields, thin-films and composites.

These facilities include, class-100 clean room, sputtering machines, optical microscopy, Raman spectroscopy, surface plasmon resonance (SPR) system, Scanning (SEM) and Transmission (TEM) Electron microscopy (within the Plymouth Electron Microscopy Centre), atomic force microscopy (AFM), electrical, impedance and magnetic measurement systems.

Deposition tools

  • 6-target and load-locked Nordiko 9550 UHV thin film deposition system
