Our comprehensive suite of microscopesLink opens in a new window are maintained by the Microscopy RTPLink opens in a new window and our expert scientists and technicians, and are used by researchers from across the university and from further afield. We also make use of major international facilities.

Ferroics

Our research addresses functional oxide materials for future information technology and energy harvesting. We pay a particular effort in understanding the fundamental physics of multiferroic tunnel junctions, abnormal photovoltaic effect and topological entities, such as domain walls and vortices, in perovskite oxides.

Oxide Interfaces

Unique materials can be created by strain engineering in complex oxides. We explore interface coupling between dissimilar electronic materials with ferroelectric, magnetic, superconducting, topological, and other functional properties to create novel multifunctional structures.

Capabilities

We are an experimental physics group who aim to go from substrate to device. Our in-house sample fabrication via Pulsed Laser Deposition is combined with a plethora of characterisation methods and advanced photolithography techniques to fully characterise materials and devices.

Materials Evaluation

Evaluating the long-term performance of materials in their target application requires studying their resilience to mechanical or radiation stress, often in-situ, making non-contact or non-destructive probes essential.

Fundamental Studies

We use our advanced ultrasound probes to make fundamental studies of elastic constants in highly correlated materials such as frustrated and single molecule magnets.

Non-destructive Testing

We use non-contact ultrasound methods in material evaluation and testing - from crystallographic texture determination in metals through to the high speed inspection of rail track.

Ultrafast & Terahertz

Our activities use ultrafast light pulses, with durations of femtoseconds, picoseconds or nanoseconds, as powerful probes of different states of matter. Different wavelengths from the far infrared (terahertz) to the infrared, visible and ultra-violet allow specific properties to be studied.

Ultrafast Spectroscopy

We use pump/probe spectroscopy to study how light and matter interact on femtosecond to nanosecond timescales. Using visible or THz probes we can track electronic processes, while infrared radiation lets us study vibrational states of molecules and atomic-scale defects in semiconductors.
