University of Carthage  | Tunisia

Dr. Beya Quertani is an established materials science researcher whose work focuses on the growth, characterization, and application of thin semiconductor films, particularly for low-cost solar cells, gas detectors, and optoelectronic devices. Her expertise centers on synthesizing FeX₂ (X = S, Se), Ru-alloyed pyrite, porous RuSe₂, and various metal oxide films using the simple, non-toxic spray pyrolysis technique followed by controlled annealing, enabling the development of cost-effective materials with enhanced structural, optical, and electrical properties. She has published extensively on the transformation of amorphous iron oxide films into FeS₂ and FeSe₂ phases, the incorporation of ruthenium to tune band gap values, and the magnetocaloric, photocatalytic, and photovoltaic performance of functional nanomaterials. Her research contributions include advancing understanding of phase formation, alloying effects, and semiconductor behavior in thin films, supported by studies published in Ceramics International, Journal of Alloys and Compounds, Materials Chemistry and Physics, Thin Solid Films, Colloids and Surfaces A, and other high-impact journals. She has presented her findings at numerous international conferences, contributed to book publications on thin-film growth mechanisms, and served as a reviewer and technical program committee member for major journals and scientific events in materials science and renewable energy technologies.
