​Assistant Professor in Physical Science and Engineering Division​


Research Interest

Prof. Iman Roqan has experience in fundamental studies of wide band gap semiconductors, mainly GaN and ZnO; the material system that enabled high efficiency LEDs. Her main specialty is investigating the role of defects and material structure by optical spectroscopy. Her group focus on investigating the optical and structural characterizations of GaN and ZnO materials with different structures: nanorods, quantum well and quantum dots materials.

They could identify the carrier mechanism such as carrier confinement behavior, quantum stark effect, carrier density and carrier injection. Moreover, they could also identify the effect of the width of the quantum well/barrier, the effect of the nanorod structure, the bandgap structure, the polarization effect, the interaction of defect bands in the spectra and the identification of their source by time-resolved spectroscopy (TRS), photoluminescence (PL) and photoluminescence excitation (PLE). Second and third Harmonic Generator and OPO facilities add additional laser tunability and allow us to do PLE and selective TRS measurements simultaneously.


Prof. Iman Roqan is an assistant professor in the Physical Sciences and Engineering Division at KAUST. She obtained her M.Sc. in optoelectronic and photonic devices from St. Andrews and Heriot-Watt Universities, United Kingdom. Her Ph.D. was obtained from the University of Strathclyde in semiconductor and spectroscopy. She also has established several collaborative projects with international universities, Saudi institutes and industrial companies.
