Alexandru B. Georgescu, an assistant professor of Chemistry at Indiana University Bloomington, has been recognized with the Oxide Electronics Prize for Excellence in Research. The award was presented during the International Workshop on Oxide Electronics (iWOE) in Banff, Canada.
The prize is awarded to three researchers under 40 each year and is determined by a panel of senior scientists from universities and research institutes worldwide. It acknowledges “pioneering contributions in understanding the interplay between electronic and crystal structures in phase transitions of correlated materials, and for developing innovative computational methods that have advanced insights into magnetic, ferroelectric, and metal-insulator transitions across multiple length scales in superlattices.”
Oxide electronics examines how electricity moves through materials made of metals and oxygen. These materials are considered highly efficient for electrical conductivity.
“Entire eras of human history have been named after the materials that shaped them, from stone to bronze to iron,” said Georgescu. “In a similar way, oxide-based electronic materials form the backbone of many of today’s most important technologies and will be central to what comes next.”
Georgescu leads a research group focused on theory and computation related to solid-state inorganic materials such as metal oxides. His group collaborates both within Indiana University—studying photoluminescent oxyhalides with faculty like Sara Skrabalak—and with other institutions nationally and internationally. Their work supports advances in fields ranging from microelectronics to quantum devices.
Second-year Ph.D. student Md. Rajbanul Akhond described his involvement: “These electronic materials are a perfect playground for applying the advanced computational and data-driven methods I’m studying,” he said. “I’m motivated by the challenge of using quantum mechanical principles, like Molecular Orbital theory and Density Functional Theory, to understand why they behave the way they do.”
First-year Chemistry Ph.D. student Madison Genslinger also commented on her experience: “Professor Georgescu’s research is very interdisciplinary and lies at the perfect intersection of chemistry, math, physics, and computer science,” she said. “As someone who is interested in most of these fields, it can be difficult to find research that blends all of them to really scratch that intellectual itch.”
According to Georgescu, his team’s theoretical efforts aim to develop predictive design rules for new electronic and quantum materials: “Our theoretical work aims to provide predictive ‘design rules’ for electronic and quantum materials of many compositions, including oxides and beyond,” he said. “By understanding how these materials behave and how their properties can be tuned, we hope to help guide the creation of devices that are more efficient or more adaptable, and in some cases, devices that simply aren’t possible yet. The potential applications range from smartphones and supercomputers to clean-energy technologies and the superconducting materials used in medical imaging.”
