FacilitiesThe ATI houses extensive facilities for the fabrication, processing, analysis and theoretical simulation of a wide range of electronic and photonic materials and devices. Major facilities include• the Ion Beam Centre, a National Facility for materials implantation and analysis • a 200 square meter clean room (down to class 100) providing a multipurpose fabrication facility• a nanofabrication laboratory including an ultra-high vacuum combined scanning tunnelling and electron beam microscope and a focused ion beam writer • an “ultrafast” lab containing femtosecond lasers for ultraviolet to terahertz spectral regions • a supercomputer laboratory comprising a 148-processor Opteron cluster and an NEC SX-6 vector supercomputer

Funding• £10M Joint Infrastructure Fund investment for the building, • £14M in other major infrastructure grants in the past two years• £1.6m new responsive mode funding in 2005.

ATI industrial links Intel, Bookham Technology, Applied Materials, Qinetiq, Infineon, Thales, Philips, Hitachi, BAe systems, FEI, and others…

ATI spinouts Polarmetrix (Fibre-optic vibration sensors for security applications); SI-LIGHT (Si-based light emitters); QFT (Field emission displays based on laser crystallisation of amorphous silicon); NanoTubix (Carbon nanotube based products) is in the pre-incubator stage.

OverviewThe University of Surrey has been awarded the 2002 Queen's Anniversary Prize. The work of Professors Adams and Sealy of ATI (pictured) led to the prize. In collaboration with industry, we have piloted leading-edge solutions in the development of devices now regarded as commonplace, such as the strained layer quantum well laser.
