BOWLER2	Simulating scanning probe spectroscopy on semiconductors
Type	Theoretical
#students	1
Orientation	Why is the scientific problem of interest at all? Scanning probe methods such as STM are immensely valuable in the investigation of nanoscale surface structures. One of the modes in which they operate is spectroscopy: for a fixed probe position, the current vs voltage behaviour is measured.
How	How is the research going to shed light on the given problem?. We have excellent results in producing STM images, but much worse results when producing STMspectra.
What	What is the specific thing that the student will do, and how does it fit inside the overall project? You will work with existing codes to investigate approaches to modelling scanning tunnelling spectroscopy, with the aim of reproducing experimental spectra from our collaborators.
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.
