Improvements in electronic materials and the development of ever-more advanced device design and fabrication strategies lie at the heart of the Information Revolution.

Overview

Much of the EMD Group research is driven by the following fundamental technological questions:

• How can the spectacular performance of Si integrated circuits be sustained as fundamental physical limitations arise?

• What alternative electronic device technologies can achieve performance specifications which exceed the capabilities of Si?

• There is an increasing need to integrate electronics and semiconductor-based sensor technology in extreme environments where high temperatures or high radiation levels may be encountered, how can we provide devices for this?

• How can quantum phenomena be harnessed in micro- and听nano-electronic devices to yield new technologies, such as quantum computers听and biotechnology?听

Since the gate length of today鈥檚 silicon MOS devices are听below 10 nm, addressing these issues necessarily requires expertise in all aspects of Nanotechnology 鈥� from nanofabrication using photon, ion and electron beams听to self-assembly of organic molecular monolayers, to听understanding and harnessing quantum mechanical behaviour present in such nanoscale devices.

Research Themes

EMD staff are key within the LCN, with its four main themes, which help the Centre deliver its science and technology mission:

Theory and Modelling

Leading techniques and technologies to simulate visualize and design nano-scale structures and devices in the biological and non-biological areas; first principles atomic/molecular level theory, systems modelling and other powerful computational tools

Nano-characterisation

The full range of optical, electron, ion and scan-probe based technologies required to image and understand nanostructures in both the biological and non-biological materials including silicon, III-V, organics and diamond, and unconventional substrates such as plastic and metal foils.

Nano-fabrication

Large clean room space with the ability to produce nano-materials and devices using various biological and non-biological materials; silicon, III-V fabrication and unconventional fabrication 鈥� e.g. organics and diamond

Systems

The range of techniques and technologies required to translate nanotechnology into workable products for industry; hybridisation and integration techniques, error handling and re-routing algorithms, methods to connect bio- and non-bio systems.

Collaboration

The EMD plays a key role in the鈥�, a joint 香港六合彩中特网 鈥� Imperial College collaboration with over听拢31M听of infrastructure funding; this has recently been supplemented by an investment in Quantum Technology, which within the LCN at 香港六合彩中特网 alone amounts to more than 拢13M. The 香港六合彩中特网 Quantum Science & Technology Institute (香港六合彩中特网Q), Directed from within the EMD group, inaugurated in May 2014, serves to coordinate and support research across the university across a range of departments and disciplines, helping to develop this fast-advancing field of research.听 This has led to collaboration with scientists听and engineers听from an increasingly diverse range of disciplines, including not only physicists and materials scientists, but also those from the Life Sciences.

The group is also very active within the 香港六合彩中特网 Centre for Micro-Biochemical Engineering and is co-investigating development programmes to fundamentally change many biopharmaceutical processes.听The interaction of electronics with cellular materials is facilitated through the links with听the 香港六合彩中特网 Great Ormond Street Institute of Child Health (ICH) which, together with its clinical partner Great Ormond Street Hospital for Children (GOSH), forms the largest concentration of children's health research in Europe.

Industrial engagement is strong, for example, with BAE Systems, Rolls-Royce and听Photonis as examples. Activities are also associated with international institutes, such as for the LHC at CERN, Geneva and the JET Fusion facility in Oxfordshire. Many current projects being pursued are pan-European being supported by the EC鈥檚 Horizon 2020 programme. This includes activities in Power Electronics and the important emergent technology known as 鈥榤em-ristors鈥�
