Materials physics lab

The Materials Physics Lab is located at the Physical Sciences Complex in the wing adjacent to Physics Building .

Lab Leader: Dr. Tabitha A. Amollo

Vision

To be a regional research hub for developing cutting-edge nanomaterials and functional devices.

Mission

To equip research students with knowledge and skills for developing innovative technological solutions to societal and global challenges.

Establishment

The materials physics lab in the Department of Physics, Egerton University, was officially launched on 11th May 2023. The equipment in the lab were acquired through research grants by the Carnegie Corporation of New York (CCNY) through the Future Africa Research Leadership (FAR-LeaF) program and the World Academy of Sciences (TWAS) (grant no. 20-187 RG/PHYS/AF/AC_I – FR3240314148). Other key equipment was donated by the World Bank.

Research focus

Research areas undertaken in the lab include nanotechnology, thin film technology, materials and device engineering for solar energy conversion, which constitute developing cutting-edge nanomaterials and technologies for the generation of electricity from solar energy. Broadly, the research aims at alleviating the global energy supply and demand challenges whilst ensuring environmental sustainability. Thus, the research contributes to the achievement of the United Nations Sustainable Development Goal seven, i.e. affordable and clean energy. The techniques utilized for thin film deposition in the lab include spin coating, thermal evaporation, and magnetron sputtering. Other techniques for nanomaterials preparation in the lab include chemical vapour deposition and solution-phase synthesis methods.
