Research Interests

Semiconductor thin film growth and characterisation particularly transparent conducting oxides that have applications in new electronics. The growth techniques used include molecular beam epitaxy, pulsed laser deposition and Mist-chemical vapour deposition. Optical characterisation is done with low temperature photoluminescence and photoconductivity.
