Designing molecules for future microchips As semiconductor manufacturers push the limits of how small microchips can become, chemistry is playing an increasingly important role in the future of computing. In the Department of Chemistry, materials scientist May Nyman and doctoral student Esther Julius design metal oxide clusters, tiny molecular structures that could help create the intricate patterns used to manufacture nextgeneration semiconductor chips. Supported in part by industry partners such as Intel, the research focuses on developing new molecules for lithography, the process used to create microscopic circuits on semiconductor wafers. As chip features shrink to the nanometer scale, traditional manufacturing approaches are reaching their limits, increasing the need for chemistry-based solutions. Julius explores how metal oxide clusters can function as advanced lithography materials while simplifying the way they are produced. Her work has reduced some synthesis processes from complex, high-temperature procedures to reactions that can be completed in minutes at room temperature. The project is part of Oregon State’s broad effort to strengthen semiconductor research and workforce development, helping prepare students and technologies for the next generation of computing. From fungi to future electronics While some researchers focus on making smaller microchips, physicist Oksana Ostroverkhova is exploring new materials that could transform how electronic devices are designed and used. Her research centers on organic semiconductors, carbon-based materials used in technologies such as OLED displays. Unlike traditional silicon semiconductors, organic materials can be flexible, lightweight and manufactured at lower temperatures, making them attractive for wearable devices, sensors and other emerging technologies. Ostroverkhova also investigates naturally occurring pigments produced by fungi. One promising material, a blue-green pigment called xylindein, forms durable, flexible crystals that can guide light and change color in response to electronic signals. The work could help create more sustainable electronic materials inspired by nature. She also researches spintronics, an emerging field that uses spin waves rather than electrical current to process information. By studying how light and matter interact at the molecular level, Ostroverkhova and her students are laying the foundation for future technologies that are more efficient, adaptable and environmentally sustainable.
