Research in our lab is centered on understanding the properties of materials and applying this fundamental understanding to develop improved materials and devices for a wide range of applications in energy harvesting and generation, electronics, displays, lighting, and sensors. We are also interested in innovative manufacturing technologies for large-area nano-electronics where the device, and ultimately system-level performance, is determined by the device's physical dimensions rather than strictly by the active material(s) employed.
In our biosensing studies, we combine materials design and device architecture to bridge the biological elements to the electronic interface. Here in LAMA lab, we explore multi-layer metal oxide thin-film transistor (TFT) as a novel biosensor for label-free and real-time detection.
Development of next generation nanoelectronics in the emerging fields of energy harvesting/conversion, Internet of Things (IoT), bioelectronics, large area electronics or thin film transistors is largely governed by the active materials. Thus, we are investigating various novel active materials such as members of transition metal dichalcogenides (TMDs) and thiocyanate (SCN) families, carbon nanotubes, quantum dots or sulfide based compounds to be incorporated into our active research areas.
Our OPV team is working on different fronts, such as fundamental studies of OPV, development of new interfacial layers, dopant formulation for device improvement, multi-junction OPV, new device concepts, and OPV devices with stretchable substrates. These efforts have a similar primary goal: understanding underlying phenomena in OPV and pushing the efficiency of OPV closer to the practical limits.
Here at KAUST our group working on the development of sub-20 nm co-planar symmetric/asymmetric nanogap electrodes fabricated on glass/arbitrary substrates using a technique so called adhesion lithography (a-lith) by combining the conventional top down & the emerging bottom up self-assembly approaches.
Metal oxides (MOs) are typically wide-bandgap materials with many properties beneficial for electronic applications. In our research we are focusing on solution processing of semiconducting and insulating metal oxides for uses in e.g. thin-film transistors (TFTs), RF nanogap diodes, or as interlayers in photovoltaic cells. We investigate innovative ways of deposition and post-treatments such as spray pyrolysis and photonic curing, which allow rapid large-area fabrication at low temperatures.
Organometal halide hybrid perovskites (HPs) combine the advantages of solution processing, high absorption coefficient, long charge diffusion length, and high mobility of inorganic framework. The high-quality films of HPs have made a significant impact on the fabrication of efficient and stable (opto)electronic devices. We develop several versatile approaches to prepare high-quality perovskite films and paves the way for high-performance and stable perovskite devices.
