Primarily we are interested in systems that have application in modern technologies, for example in nanoscience and biophysics. Current projects are related to novel devices in the fields of molecular and opto-electronics, quantum information theory and magnetic sensing. We are increasingly working with industrial organisations concerned with nano-fabrication of electronic devices and high-density magnetic recording.

We are involved in both national and international collaborations and are currently involved in both EPSRC and EU funded projects. We make extensive use of central facilities such as DIAMOND and the ESRF.  As part of the Mathematical Modelling Center in Leicester we have access to the Newton supercomputer cluster.

Research

What is Condensed Matter Physics?

Broadly speaking, condensed matter physics is concerned with the behaviour of matter on an atomic scale. The CMP group at Leicester are interested in the relationship between atomic configurations, electronic structure and function.

• More information on CMP research projects is available on the research page.

Theory

We are primarily interested in the structural and electronic properties of semiconductor nanostructures.

We use numerical and analytical techniques to model both the single particle and strongly correlated quantum states of semiconductor nanostructures.These, artificial atom-like systems have important applications in opto-electronics and quantum computing. We study many types of semiconductor nanostructures: self assembled MBE grown dots, electrostatic dots, and quantum dots formed in carbon nanotubes (image: right) or graphene.

The group is also interested in X-ray and electron scattering. We use advanced computational techniques to accurately solve the quantum mechanical behaviour of electrons interacting with non periodic arrays of atoms or ions.

Experiment

We use a wide range of techniques to produce and investigate novel nanoscale materials.

Much of our research program is based upon a custom made nanocluster source: L.U.M.P.S. (image: right) is capable of producing size selected metal nanoclusters of roughly a few hundred atoms. The clusters have novel structural and magnetic properties and we are currently developing more advanced cluster sources capable of producing nanoclusters with core-shell geometries.

The CMP scanning probe facility is also equipped with a low temperature AFM/STM (image: left). We are currently using the AFM to investigate the Casimir force - one of the most fundamental forces in the universe. A large proportion of our experimental work, including the microscopy, is carried out at ultrahigh vacuum (< 10^-10mbar).

The group is a large user of central facilties in both the UK and abroad. We use synchrotron radiation techniques including magnetic x-ray circular and linear dichroism (MCXD, MCLD), surface x-ray diffraction (SXRD), photoelectron spectroscopy, and small angle x-ray scattering (SAXS).

Teaching

Staff from the CMP group teach subjects such as nanotechnology, atomic physics, semiconductors and quantum mechanics. Lecture notes and course details can be found by following the links on the homepages of individual members of staff.

PhD places are available in most years, in most areas of research covered by the group, depending on the prospective students interests. Find out more about PhD opportunities.

Every summer the department runs an undergraduate research program (SURE) with opportunities for paid employment in the department research groups. Find out more about the SURE programme.
