KAUST Assistant Professor Xiaohang Li has won the 2018 Harold M. Manasevit Young Investigator Award for his work in metal-organic chemical vapor deposition (MOCVD) growth of semiconductors. Li will receive the award at the 19th International Conference on Metalorganic Vapor Phase Epitaxy in Japan. The award recognizes Li's contributions to deep UV lasers, B-III-N alloys, III-oxides, and blue and green emitters. Why it matters: This award highlights KAUST's growing prominence in advanced semiconductor research and its potential impact on the optoelectronics industry.
KAUST has acquired a BM Pro plasma-enhanced chemical vapor deposition (PE-CVD) reactor from AIXTRON for wafer-scale deposition of graphene and carbon nanotubes. The reactor, capable of handling up to 4-inch substrates, will be used by Professor Pedro Da Costa's research team initially, before being opened up to other researchers at KAUST. AIXTRON's VP highlighted the system's uniformity, scalability, rapid heating, and plasma-based processing for growing graphene and nanotubes. Why it matters: This advanced tool enhances KAUST's research capabilities in carbon nanostructures, positioning the university as a leading center for materials science and nanotechnology research in the region.
KAUST Professor Mohamed Eddaoudi is researching MOFs (metal-organic frameworks). MOFs have applications for clean energy. Why it matters: This research contributes to KAUST's and Saudi Arabia's broader clean energy and sustainability initiatives.
KAUST Discovery highlighted Prof. Karl Leo's insights on translating science into business from an Entrepreneurship Center speaker series. Prof. Leo, with 440 publications and 8 co-founded companies, emphasized the importance of curiosity-driven basic research. He envisions organic semiconductors dominating electronics in 20-30 years, noting the success of Novaled, his OLED company in Dresden. Why it matters: This underscores KAUST's focus on fostering entrepreneurship and translating research into practical applications within the Kingdom.
KAUST researchers are exploring thin-film device technologies using materials like printable organics and metal oxides for a greener Internet of Things (IoT). They propose wirelessly powered sensor nodes using energy harvesters to reduce reliance on batteries, which are costly and environmentally harmful. Large-area electronics, printed on flexible substrates, offer a more eco-friendly alternative to silicon-based technologies due to solution-based processing and lower production temperatures. Why it matters: This research contributes to a more sustainable and environmentally friendly IoT ecosystem, aligning with global efforts to reduce electronic waste and energy consumption.
A KAUST research team led by Prof. Osman Bakr developed a novel antisolvent vapor-assisted crystallization (AVC) method to grow high-quality, crack-free MAPbX3 perovskite single crystals at room temperature. The resulting crystals exceeded 100 mm3 in volume and exhibited exceptionally low trap-state density (approximately 10^9 – 10^10 cm-3). The crystal quality is comparable to high-quality single crystal silicon, but grown at much lower temperatures. Why it matters: This breakthrough allows for more accurate characterization of perovskite photovoltaic properties and can accelerate improvements in solar cell efficiency.
KAUST researchers found that inserting a magnesium fluoride layer in perovskite–silicon tandem solar cells can stall charge recombination and enhance performance. The magnesium fluoride interlayer effectively promoted electron extraction from the perovskite active layer and reduced charge recombination at the interface. The resulting tandem solar cell achieved a stabilized power conversion efficiency of 29.1%. Why it matters: Improving the efficiency of solar cells is critical for expanding renewable energy capacity in Saudi Arabia and worldwide.
KAUST postdoctoral fellow Ming-Hui Chiu, from the Physical Science and Engineering division, focuses on 2D material heterostructure synthesis and characterization utilizing chemical vapor deposition (CVD) technology. His research aims to develop and optimize CVD for transition metal dichalcogenides (TMDs) growth, which could replace silicon in sub-nm scale devices. Chiu values KAUST's resources, interactions with researchers, and work-life balance. Why it matters: This research contributes to the advancement of next-generation electronic devices using 2D materials, positioning KAUST as a hub for cutting-edge materials science.
