Description We developed techniques to improve the quality of devices fabricated out of 2D materials. Treating the 2D materials before and after fabrication will create better material-material and material-substrate interfaces, and adjust strain. This has the potential to create new sources of variability in the material properties.

Techniques to improve mechanical exfoliation, transfers and stacking of 2D materials were optimised to increase yield.

These methods make it easier to make higher-quality devices with 2D materials, including deliberately tuning their properties (eg. Inducing strain)

Modification of the optical properties of 2D materials were investigated using the addition of gold nanoparticles. These local modifications from the random positioning of the nanoparticles have the potential to improve optical physical unclonable functions as unique objects for security and anti-counterfeiting purposes.
Exploitation Route Fabrication and characterisation techniques were developed, improved and optimised so future PhD students/postdocs can use the same techniques to fabricate higher quality devices.
