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.
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 Professor of Electrical Engineering Kazuhiro Ohkawa has been elected as a Fellow of the Japan Society of Applied Physics (JSAP). JSAP recognized Ohkawa for his contributions to the development of wide bandgap semiconductor epitaxial growth and optical devices. Ohkawa's research at KAUST focuses on energy-conversion phenomena for sustainability, including doping technologies, MOCVD for nitride semiconductors, and nitride photocatalysts. Why it matters: Recognition of KAUST faculty in international societies raises the university's profile and highlights its contributions to applied physics and sustainable energy research.
KAUST aims to become a leader in wide-bandgap semiconductor research, recognizing the technology's crucial role in diversifying Saudi Arabia's economy. Compound semiconductors are highlighted as the second most used type after silicon because of their superior properties. KAUST President Dr. Tony F. Chan emphasized the strategic importance of semiconductors and their potential to transform Saudi Arabia's digital economy, manufacturing, and defense industries. Why it matters: This initiative signals Saudi Arabia's strategic interest in developing a local semiconductor industry, crucial for its AI ambitions and economic diversification goals.
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 have fabricated and tested high-efficiency perovskite-silicon tandem solar cells optimized for hot climates. The tandem device is more stable than conventional perovskite cells and optimized for industry use. Outdoor testing at KAUST confirmed performance improvements, indicating bromide-lean perovskite top cells with narrower bandgaps are ideal. Why it matters: The research demonstrates the viability of tandem silicon-perovskite cells in harsh environments, paving the way for more efficient solar technology in the region and globally.
