About

Prof Kar Seng (Vincent) Teng is the Head of Department of Electronic and Electrical Engineering and also leads the Nanoelectronics Research Group in the Department.

His research interest is in the study of nanoscale electronic materials and devices. This involves research into low-dimensional electronic materials, such as graphene, metal-oxide and nitride nanostructures etc, in the development of novel devices for applications in healthcare, optoelectronics and energy technologies.

Prof Teng's expertise is in the designing, fabrication and characterisation of nanoscale electronic materials and devices, as well as controlling their properties through surface engineering for novel applications. His expertise also includes the development of scaling-up technologies for nanotechnology-based devices to ensure commercial viability, the use of scanning probe microscopy and other surface science techniques for the study of semiconductor surfaces and interfaces.

His research has been supported by awards from the NHS-National Institute for Health Research (NIHR), European Commission Horizon 2020, The Royal Society, Welsh Government, HEFCW, Sir Halley Stewart Trust and industries etc. He is the principal inventor on at least ten patents/patent applications. Prof Teng also serves as an Associate Editor for the Royal Society of Chemistry (RSC) Advances and as technical committee member for a number of international conferences in the area of Nanotechnology and Material Sciences.
