Electronic Materials and Sensors Research Group

About the group

The Electronic Materials & Sensors Group is a highly active research group led by I. M. Dharmadasa, who is the Professor of Electronic Materials & Devices, and currently focusing on Solar Energy conversion.

The group is dedicated to the training of scientists and engineers in understanding of all aspects of Electronic Materials and Sensing Devices.

The activities in the group focus on

  • growth of electronic materials using Electrodeposition, Chemical Bath deposition, Sol-gel, vacuum evaporation, etc.
  • material characterisation using a wide range of analytical techniques (Facilities Available)
  • device design, fabrication,  assesment, development and commercialisation of PV solar cells, LEDs, sensors, etc.
  • modelling of electronic device structures (lasers, graded bandgap solar cells)
  • scaling up and commercialisation of successful research
  • public understanding of science activities on renewable energy applications and sustainability (http://www.apsl.org.uk/dharme/default.aspx)
  • theory and simulations of transport and optics of intersubband semiconductor materials and devices with an emphasis on mid infrared and terahertz applications. Main devices currently focused are cascade lasers and graded bandgap multi-layer solar cells.

Case study - Synergic Chemical Analysis:'There's no smoke without fire — or is there?'

A series of case studies illustrating how access to Sophisticated Evolved Gas Analysis can provide manufacturers with information about the gases evolved when materials are heated.

Solar Energy Research, Development and Commercialisation Programme

We are working on thin-film photovoltaic (PV) solar cells based on the CdTe, CuInGaSe2 (CIGS), GaAs/AlGaAs and organic/inorganic hybrid structures.

The focus is on reducing the cost of solar to electrical energy conversion by using electrodeposition as a low cost material growth technique, and developing novel graded bandgap device structures with the highest possible efficiency. Innovative new ideas have been protected in six new patents and subsequently published in the literature during the past four years.

Electronic materials analysis

Our electronic materials characterisation facilities include the following
