Abdul Rahman Mohmad
Rahman completed his MEng in Microelectronics from the University of Sheffield in 2008. He was also awarded the ‘Hector Aitken Wainwright Prize’ from the university for academic excellence. Later, he joined Universiti Kebangsaan Malaysia (UKM) as a junior research fellow. In April 2009, he returned to University of Sheffield to pursue his PhD. Rahman is currently involved in the growth and characterisation of GaAsBi alloys. To date, he has published three first-authored papers in Applied Physics Letters. He is expected to complete his PhD in January 2013. Outside working hours, Rahman dedicates most of his time to his family and humanitarian causes.
Chris graduated from Bristol in 2009 with a first-class MSci in Chemical Physics. After deciding to apply for research positions, he successfully gained a place on the E-Futures Doctoral Training Centre programme starting later that year.
In the first year of the programme he undertook a range of mini-projects relating to energy. After the first year he began his PhD project in Electronic and Electrical Engineering, looking at the semiconductor material gallium arsenide bismide (GaAsBi) for potential solar cell applications. His work involves processing and characterization of GaAs p-i-n diodes containing undoped GaAsBi layers. The presence of these layers has been shown to extend the photoresponse into the near-infrared. A paper based on this work has been accepted for publication in Photonics Technology Letters (see publications page for further details).
In his spare time he enjoys cooking, playing guitar and creating digital art.
Rob received his Mphys degree from Sheffield University in 2009, the final year of this project focussed on organic photovoltaics (OPV). He successfully applied for a place in the e-futures doctoral training centre in the same year and, after a year of energy systems study, decided to return to photovoltaics (PV) for his PhD, albeit this time inorganic PV with the department of Electronic and Electrical Engineering. Rob focussed on multiple quantum well (MQW) and multi-junction (MJ) solar cells for the first year of his PhD before moving into molceular beam epitaxy (MBE). He is now working on fundamental GaAsBi growth science, such as temperature and elemental flux ratio dependence of Bi incorporation as well as practical device studies looking at the potential of GaAsBi/GaAs MQW systems for use as a 1eV junction in MJ PV. In his spare time Rob is president of the Sheffield University sign language society and plays drums and guitar (not simultaneously) for the Ceilidh society.
Danuta completed her MSc in Semiconductor Photonics and Electronics from the University of Sheffield in 2011. Her dissertation work involved electrical and optical characterisation of Interfacial Misfit arrays. She joined Faebian’s MBE lab in August 2012 and is currently training to develop her skills as an MBE grower. In her spare time you could find her cooking curries, knitting, quilling, writing poems and more recently baking!
Hanno received his Bphys from Goethe University Frankfurt in 2011 following an internship at the institue of solar research of the German Aerospace Center in Spain involving qualilfication measurements of mirror panels and irradiance calculations. Afterwards he resumed his studies at Humboldt University Berlin and worked as a student assistent in the epitaxy group of the Fraunhofer Heinricht Hertz Institute where he was introduced to MOVPE growth of InP systems. In June 2013 he started work on his Masters Thesis at Paul-Drude-Institute which is based on GaAs nanowire growth on pre-patterned substrates. In his spare time he is recently interested in sailing and Vipassana meditation.
