LEEM-MBE nanostructure nucleation dynamics (physics)
Cardiff University hosts a worldwide unique facility consisting of a Low Energy Electron Microscope combined with an As-based Molecular Beam Epitaxy system. The system allows us to make videos of the growth of As-based thin films with 5 nm resolution in the plane and atomic resolution in the vertical direction, as well as observe diffraction and photoemission of the crystal we are growing. The goal of the project is to study the formation of 0D, 1D and 2D nanostructures during the nucleation stages of GaAs, as well as formation and dynamics of defects. The knowledge will be applied to the fabrication of new semiconductor devices, with the goal of eventually replacing current Silicon electronics. This particular project involves technical work with an Ultra High Vacuum system, electron microscopy, and molecular beam epitaxy growth as well as image processing and analysis. The experimental work will be carried out in very close relationship with world-leading theorists within the group and through collaborations.
This project is available to students applying for funded PhD studentships and may be altered or amended.
Studentships will be awarded to successful applicants from all applications received. Applicants must satisfy RCUK residency rules for the full studentship.
