I am an expert on hetero-epitaxial growth of ultra-thin films, thin films, quantum well (QW), superlattice (SL), quantum dots (QD), nanostructures (nanowires) with a sub-monolayer and monolayer precision by Molecular Beam Epitaxy (MBE). I am in-charge of advanced material epitaxy laboratory (AMEL) which host a unique dual-chamber Veeco Gen 930 MBE reactor with III-Antimoide and III-Nitride growth capability.

My research focus is on heteroepitaxy, characterisation and fabrication of III-V compound semiconductors devices:

i)  Detectors and Emitters: Light-emitting diodes (LED), photodiodes (PD), avalanche photodiode (APD) and focal plane array (FPA) for UV to LWIR wavelength range for sensing, detection, thermal imaging,

ii) Thermophotovoltaic (TPV) cell, Solar-Thermo PhotoVoltaic (STPV) cells for resilient waste heat energy generation and solar energy harvesting, and

iii) Photovoltaic-photoelectrochemical cells (PV-PEC) for hydrogen generation and water purification via solar energy.


I am a Lecturer (Teaching and Research) and a member of the CMP group at Cardiff University School of Physics and Astronomy.  I am CMP outreach representative.
