Yue Zhao, assistant professor of electrical engineering, has received a $500,000 grant from the National Science Foundation’s Faculty Early Career Program to support his research on silicon carbide motor drives. Silicon carbide devices can be used to make high-power motor drives to power electric and hybrid electric vehicles, and “more electric” aircraft and ships. Developing […]
University Of Arkansas Researchers Extend BKT Physics To Study Of Ferroelectrics
Researchers at the University of Arkansas investigating critical properties of ferroelectric thin films – which have applications in sensors, actuators and memory devices – have shed light on an overlooked phase of the material. Since its discovery about four decades ago, the Berezinskii-Kosterlitz-Thouless (BKT) theory has provided a new understanding of phase transitions in two […]
DISTRO: Researchers Create Digital Objects From Incomplete 3D Data
“Although the 3D scanning technology has made significant progress in recent years, it is still a challenge to capture the geometry and shape of a real object digitally and automatically,” explains Mario Fritz, who leads the group “Scalable Learning and Perception” at the Max Planck Institute for Informatics. According to Fritz, depth sensors, such as […]
Germanium Tin for Cheaper Smartphones
Engineering researchers at the University of Arkansas have fabricated a new semiconductor material – germanium tin deposited in layers on a substrate of silicon – that could be used to build better and less expensive infrared cameras for smartphones and vehicles. “The performance of these simple structures indicates a promising future for germanium tin photodetectors,” […]
Scientists Track Ripples in Freestanding Graphene
An international team of physicists, led by a research group at the University of Arkansas, has discovered that heating can be used to control the curvature of ripples in freestanding graphene. The finding provides fundamental insight into understanding the influence temperature exerts on the dynamics of freestanding graphene. This may drive future applications of the […]
