Orientation |
Why is
the scientific problem of interest at all? Transition
metal-based phthalocyanines are organic molecules which can carry a spin on
the metal atom at their centre. In this project, you will model the adsorption of an iron-based molecule
on Si(111), developing earlier work on haem molecules on
silicon. |
How |
How is
the research going to shed light on the given problem?. Recent STM data shows very strong changes in images
with voltage, and we will aim to reproduce these changes with electronic
techniques. Understanding how these molecules adsorb and can be
controlled is directly applicable to spintronic applications. |
What |
What is the specific
thing that the student will do, and how does it fit inside the overall
project? The student will model the atomic, electronic and
spin structure of phthalocyanines on Si(111) and generate STM images from
these simulations. These will be
compared with experimental data and the behavior of the molecules under
different conditions on the surface will be examined. |
Special Knowledge |
The project is based around computational
simulations, and the student will be expected to learn how to use Unix-based
operating systems as well as density functional theory codes. An
interest in computing and computational and/or theoretical physics would be an
advantage. |
