Summary on Grant Application Form |
|
The project will use state-of-the-art computer simulation and quantum mechanical techniques to investigate the interaction of tips with the surface of a range of insulating solids. The work is motivated by the need for guidance from explicit atomistic modelling methods of the factors controlling tip surface interactions in AFM studies. The calculations will involve scanning a realistic atomistic model of tips of relevant materials (including Si3N4) over the simulated surfaces (of e.g. SiO2 and MgO). The recent developed MARVIN code will be employed for these calculations. The quantum mechanical studies (using the CLUSTER code) will allow us to investigate details of the chemical state of the tips and of chemical interactions between the surface and tip. The project will require both code development and applications; the latter will pay particular attention to imaging surface defects and sorbed molecules on oxide and halide systems.
