UCSB Materials professor Chris Van de Walle has been awarded the 2023 Materials Theory Award from the Materials Research Society (MRS), the leading professional society dedicated to advancing materials science. MRS gives a single Theory Award each year, in recognition of “exceptional advances made by materials theory to the fundamental understanding of the structure and behavior of materials.”
Van de Walle was recognized specifically for his contributions in developing ab initio (first principles) methodologies for understanding how point defects affect light emission in wide-bandgap semiconductors. The award includes a $5,000 cash prize, a trophy, and a certificate, presented at the Fall 2023 MRS meeting.
The award is a significant milestone in Van de Walle’s remarkable research career, during which he has coupled mastery of computational and condensed-matter physics with an ability to identify critical challenges related to technological applications.
Along with his work on point defects, he has made significant contributions to the understanding of interfaces and nonradiative recombination rates in semiconductor materials. His findings have induced paradigm shifts in the understanding of semiconductors, and his publications serve as authoritative guides in the field.
The impact of his work is evident not only in prizes such as the MRS Theory Award, but equally through the remarkable number of citations to his publications, which, for the past six years, have earned him distinction as a Highly Cited Research on the annual list produced by Clarivate Analytics.
“I was thrilled to receive the news of this award,” commented Van de Walle. “My work is based on computational physics and is quite fundamental in nature. While I have always put great emphasis on making connections to real-world applications, it wasn’t evident that this impact would be readily recognized. The award confirms that I have had some success in communicating our results to experimentalists who seek guidance in understanding and designing materials.”
Van de Walle also acknowledged the essential contributions of students and postdocs to the work recognized by the award. Noting further that his career has been enabled by the welcoming atmosphere he encountered when he arrived in the United States as a student back in the 1980s., he said, “Maintaining such an open door is essential to the success of the United States as a leader on a global scale."
