advancing electronics and photonics through

interdisciplinary research

Advanced Technology Institute

The Advanced Technology Institute at Surrey is shaping tomorrow’s technology with a unique blend of applied research inspired by theory,

carried out by research teams with broad multidisciplinary research expertise in electronics, physics, material science, chemistry and biology.

• Addressing the grand challenges in information technology, renewable energy, and health-care technology

• 3 decades of leading research with significant impact on ICT industries (e.g. rapid thermal annealing, SIMOX, strained layer lasers)

• Major current activities in nanotechnology, photonics, ion beams and advanced theory & computation

• Spin outs since 2002: 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), Surrey Nano Systems (Carbon nanotube growth systems )
