We performed spatial Raman mapping on supported monolayer graphene carved by 30 keV He + beam. A tilted beam was introduced to effectively eliminate the substrate swelling. The ratio between D and G peak intensities shows that Stage 1 and Stage 2 dis

We report the fabrication and characterisation of a suspended double-clamped beam structure that is implemented as a movable control gate within a hybrid high-speed non-volatile memory device. This structure features a foundation of SiO"2/Si layers o

This paper investigates the behaviour of a defective single-gate bilayer graphene transistor. Point defects were introduced into pristine graphene crystal structure using a tightly focused helium ion beam. The transfer characteristics of the exposed

The use of a helium ion microscope with an integrated gas injection system for nanofabrication is explored by demonstrating the milling of fine features into single layered graphene and the controlled deposition of tungsten and platinum wires from ga

We present a wavelet analysis of coarsening of mounds during molecular beam epitaxy. The advantage in using wavelets over Fourier analysis is that one can track the coarsening process in both, location (direct space) and frequency (or scale) space at

We present an analytical model for the powder blasting of brittle materials with sharp particles. We developed a continuum equation, which describes the surface evolution during the powder blasting, into which we introduced surface energetics as the

We have fabricated curved optical micromirrors on silicon. We expect to be able to form open optical cavities between these mirrors and plane mirrors coated on the ends of optical fibres. The curved mirror templates have been prepared with less than

We investigated a method of forming tunnel barriers in monolayer graphene nanoribbon (GNR) using controlled ion irradiation. By using a helium ion microscope (HIM), we are able to reduce the width of exposure area down to 5nm. Source-drain conductanc

We present results on electronic transport in disordered graphene nanowire field effect transistors. We show the emergence of unipolar transport where increasing defects density yield almost an insulating behaviour in n-type graphene whilst showing a
