Mr Benjamin King

  • Research Associate in Green-Large Area Electronics (Electronic & Nanoscale Engineering)

Biography

Benjamin received his B.A.Sc. in Chemical Engineering in 2019 and was awarded his Ph.D. in Chemical Engineering in May of 2024 from the University of Ottawa.

Dr. King joined the University of Glasgow in March of 2024 as a research associate, where he is working with the Green RF-enabled electronics lab under the supervision of Dr. Mahmoud Wagih as part of the EPSRC-funded project DIELECT.

Research interests

My research interests are related to the interfacing of novel functional materials with electronic devices towards the development of green, large-area electronics and sensors.
  • Processing and characterization of thin-film conductors and semiconductors for applications in thin-film sensors:
    • Thin-film deposition from bench-scale evaporation and spin coating to large-area screen printing. 
    • Metrology studies of materials to develop structure-function relationships between materials, thin-film morphology and device performance.
    • Optical and electronic characterization of advanced functional materials including molecular semiconductors and polymers.
  • Material / device co-design for high-performance sensors
    • Developing fit-for-purpose materials and films for electronic devices and larger systems.
  • Chipless and wireless RF sensing
    • Integration of novel sensing materials into high-frequency devices including RLC coils for environmental sensing.
