Martin KuballMartin Kuball publications indexed by Google Scholar is the chair of the Royal Academy of Engineering in Emerging Technologies, professor in physics at the University of Bristol, United Kingdom, and director of the Centre for Device Thermography and Reliability (CDTR).
Education Kuball received his Diplom from the University of Kaiserslautern, Germany and his PhD from the Max Planck Institute for Solid State Physics, Stuttgart, Germany, During his PhD he worked with Manuel Cardona. Prior to joining the University of Bristol he was Feodor Lynen Fellow of the Alexander von Humboldt Foundation at Brown University working with Arto Nurmikko.
Career and research Kuball is known for his research into thermal characterization and reliability of electronic materials and devices, with particular focus on wide-bandgap semiconductors, and RF and power electronic devices. He pioneered techniques such as Raman thermography, based on Raman spectroscopy, to determine temperature in devices with submicron spatial resolution and nanosecond time resolution,Measurement of temperature in active high-power AlGaN/GaN HFETs using Raman spectroscopy M Kuball, JM Hayes, MJ Uren, I Martin, JCH Birbeck, RS Balmer, BT Hughes, IEEE Electron Device Letters 23 (1), pp 7-9 (2002) https://doi.org/10.1109/55.974795M Kuball and JW Pomeroy, A Review of Raman Thermography for Electronic and Opto-Electronic Device Measurement With Submicron Spatial and Nanosecond Temporal Resolution, IEEE Transactions on Device and Materials Reliability 16 (4), pp 667 - 684 (2016) https://doi.org/10.1109/TDMR.2016.2617458 and numerous other techniques for the thermalJW Pomeroy, R Baranyai Simon, H Sun, D Francis, F Faili, DJ Twitchen, M Kuball, Contactless thermal boundary resistance measurement of GaN-on-diamond wafers, IEEE Electron Device Letters 35 (10), pp 1007-1009 (2014) https://doi.org/10.1109/LED.2014.2350075J Anaya, S Rossi, M Alomari, E Kohn, L Tóth, B Pécz, KD Hobart, TJ Anderson, TI Feygelson, BB Pate, M Kuball, Control of the in-plane thermal conductivity of ultra-thin nanocrystalline diamond films through the grain and grain boundary properties, Acta Materialia 103, pp 141-152 (2016) https://doi.org/10.1016/j.actamat.2015.09.045 and electrical characterizationMJ Uren, J Moreke, M Kuball, Buffer design to minimize current collapse in GaN/AlGaN HFETs, IEEE Transactions on Electron Devices 59 (12), pp 3327-3333 (2012) doi:10.1109/TED.2012.2216535MJ Uren, M Cäsar, MA Gajda, M Kuball, Applied Physics Letters 104 (26), pp 263505 doi:10.1063/1.4885695] of materials and devices including for understanding device reliability. Raman Thermography was used by multiple companies to qualify GaN transistor technology for space applications.UK Research and Innovation In 2019, he founded TherMap Solutions to commercialize techniques he developed and is presently its chief business officer.
He presently leads the £5M EPSRC Programme Grant GaN-DaMEIntegrated GaN-Diamond Microwave Electronics: From Materials, Transistors to MMICs which develops GaN-on-Diamond technology for ultra high power RF devices, and the £2M EPSRC Platform grant MANGI which implements this technology for next generation internet applications.
Awards and honours In recognition for his achievements, Kuball was awarded a Royal Academy of Engineering chair in emerging technologies,Royal Academy of Engineering was elevated to fellow of the Institute of Electrical and Electronics Engineers, of the Materials Research Society, of Society of Photo-Optical Instrumentation Engineers, Institution of Engineering and Technology and the Institute of Physics.New fellows, new members and In Memoriam in September 2016Fellow (FInstP) Kuball has also won numerous awards including the Otto-Hahn-Award for Young Scientists in 1995, He Bong Kim Award in 2010, Royal Society Wolfson Award, in 2015, and TechWorks Group of the Year Award in 2017
