The Organophotonics Research Group has three separate nanotechnology projects at the moment. They involve composite structures of II-IV semiconductor nanocrystals or nanotubes in organic polymer matrices for electroluminescent displays or photovoltaic cells.
Combining interdisciplinary teaching with cutting edge research, this flagship course will train the next generation of nanotechnologists. The course is associated with the London Centre for Nanotechnology, a joint venture between Imperial College London and UCL, allowing a wider choice of collaborative opportunities.
The main research topics are: Nanomagnetic Logic Devices; Nanoscale Hall-probe Devices; Technology for Preventing Forgery; Smart Nanoparticles for Targeted Cancer Treatment; Fundamental Properties of Nanoscale Magnetism.
Gain experience of research in the rapidly developing interdisciplinary areas of biophotonics, nanomaterials and nanophotonics, X-ray physics and computational modelling. Consists of taught components plus a research project. Ideal preparation for a higher physics degree or careers in scientific research or the financial sector.
The Quantum Technology Centre contains state-of-the-art nanofabrication facilities, supported by molecular beam epitaxy reactors for atomic layer-by-layer growth of semiconductor nanostructures and devices. Fabrication techniques available include electron-beam lithography using a dedicated electron-beam writer, plasma processing and thin-film deposition. Electronic structures are measured at temperatures down to 10 mK and below by means of DC, microwave and pulse techniques. Photonic structures are characterized using a variety of specialist (0-17 Tesla) magneto-optics and (4-300 K) spectroscopy techniques, x-ray diffraction, electron microscopy and atomic force microscopy methods.
Many new nanotechnology research fields require a high degree of precision in both observing and manipulating materials at the atomic level. The advanced nanorobotics technology needed to manipulate materials at the nanoscale is being developed in the new Sheffield NANOLAB.
The ETM group focuses on unique strengths and capabilities to conduct world leading research, benefiting from synergies between: microelectronics; materials research and design to simulate nanostructures and technology processes and devices; fabrication in two in-house class 100-1000 clean rooms; characterisation of materials, devices and circuits; research on emerging electronic technologies
Research activities in the group encompass a wide range of themes at the cutting-edge of nanoscale science and nanotechnology - principal interests lie in the synthesis and characterisation of new nanomaterials, such as nanodiamonds, silicon nanocrystals, gold nitride (AuN) and photon reactions on ice.
