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 have developed an artificial electronic retina mimicking the behavior of rod retina cells, utilizing a hybrid perovskite material (MAPbBr3) embedded in PVDF-TrFE-CEF. The photoreceptor array, made of metal-insulator-metal capacitors, detects light intensity through changes in electrical capacitance. Connected to a CMOS-sensing circuit and a spiking neural network, the 4x4 array achieved around 70 percent accuracy in recognizing handwritten numbers. Why it matters: This research paves the way for energy-efficient neuromorphic vision sensors and advanced computer vision applications, potentially revolutionizing camera technology.
Prof. Simon Gröblacher from Delft University of Technology presented a seminar on using mechanical systems in quantum information processing, focusing on their potential as quantum memories and transducers. The seminar highlighted experiments demonstrating non-classical behavior of mechanical motion by coupling a micro-fabricated acoustic resonator to single optical photons. Quantum control over acoustic motion was established, including the generation and readout of single phononic excitations, along with light-matter entanglement. Why it matters: This research advances the use of micro-fabricated acoustic resonators for quantum information processing and fundamental tests of quantum physics.
KAUST faculty member Enrico Traversa is researching nanostructured materials for sustainable development in energy, environment, healthcare, and solid oxide fuel cells (SOFCs).

KAUST researchers developed a crystallization process for organic molecules with potential applications in electronics, pharmaceuticals, and food. They produced "strained organic semiconductors," which can lead to high-performance, low-cost, flexible, and transparent electronic devices. The team combined X-ray beams with high-speed cameras to record the crystallization process, revealing that quick evaporation and nanoscale thinness play a role in producing ideal crystal lattices. Why it matters: This new method offers unprecedented control over crystal formation, potentially revolutionizing the production of plastic electronics and impacting other industries relying on specific crystal structures.
