Dr Alton Horsfall
Reader in Semiconductor Technology

Background

Dr Alton Horsfall joined the department in August 1999 as a research associate developing high temperature power electronics using silicon carbide. He previously completed his degree and Ph.D. at the physics department at the University of Durham where he investigated the effect of quantum mechanical exchange mechanisms in diluted magnetic semiconductors at mK temperatures. Alton then worked for the Defence Evaluation and Research Agency before moving to Newcastle.  During his time at the University he spent nine months on a Royal Academy of Engineering secondment to BAE Systems Submarine Solutions in Barrow in Furness, where he worked as part of the Instrumentation and Calibration Services team.

He is currently Reader in Semiconductor Technology and is leading the research into resilient electronic systems for high temperature hostile environments, such as those found in aerospace, defence and oil and gas exploration.  In addition to his continued work on power electronic systems, he is developing a variety of sensor based circuits, which can selectively detect a range of pollutant gases at temperatures above 300C, as well as communications systems. His research is supported by a number of industrial collaborators, including BAE Systems and Raytheon UK, as well as EPSRC.

To date he has won four best paper prizes, the IEEE International Conference on Microelectronic Test Structures (2004), the IEEE Power Electronics Conference at Illinois (2012), the deBeers Diamond Conference (2012) and IEEE Sensors (2012)

Alton is a member of the Emerging Technology and Materials research group and his profile can be viewed on  Google Scholar.

Research Interests

By utilising novel semiconductor materials, including graphene, silicon carbide, diamond and molybdenum disulphide, research is investigating the possibility of placing electronic devices and circuits in hostile environments from jet engines to volcanoes and nuclear reactors to outerspace.  Recent developments include wireless communications operating at over 300C, highly responsive gas and solvent sensors and energy harvesting technologies.  Projects involve aspects of materials science, device design and fabrication, simulation and test to understand how the desired device characteristics can be realised from these materials.  Projects are often in conjunction with leading UK companies, including BAE Systems, Raytheon UK, Rolls Royce and Dynex Semiconductors.
