Novel liquid crystal metalens offers electric zoom

Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focused using voltage instead of mechanically moving its components. Read more

Researchers create ‘beautiful marriage’ of quantum enemies

By: Syl Kacapyr

A newly published Science Advances paper was generated by a multidisciplinary team, including AEP co-authors Professor David Muller and Ph.D. candidate Phillip Dang. Collaborators included Cornell's Department of Materials Science and Engineering, School of Electrical and Computer Engineering and the Department of Physics, along with the Kavli Institute at Cornell for Nanoscale Science, the National High Magnetic Field Laboratory, Qorvo Inc. and the United States Naval Research Laboratory. This type of multidisciplinary research is what sets Cornell apart, and particularly defines AEP. Learn... Read more

Ultrawide bandgap gives material high-power potential

By: David Nutt

A Cornell collaboration has found a way to grow a single crystalline layer of alpha-aluminum gallium oxide that has the widest energy bandgap to date – a discovery that clears the way for new semiconductors that will handle higher voltages, higher power densities and higher frequencies than previously seen. The collaboration was led by co-senior authors Debdeep Jena and Huili Grace Xing, both professors in electrical and computer engineering and in materials science and engineering. The team also included David Muller, the Samuel B. Eckert Professor in Applied and Engineering Physics, who... Read more

Greg Fuchs and Jie Shan named 2020 Research Excellence Award Winners

Associate Professor Greg Fuchs and Professor Jie Shan were both awarded the 2020 Research Excellence Award from Cornell College of Engineering, given to faculty in recognition of research contributions and leadership. Nine awards were given to Cornell Engineering faculty this year. Research Excellence Awards were first established in 2015 to recognize the importance of leadership in innovative research. Past AEP faculty to receive the award include Professor David Muller (2018) and Professor Chris Xu (2017). Learn more about this year's awardees and past winners on the Research Excellence...

two-dimensional semi-conductors, stacked

Researchers trap electrons to create elusive crystal

By: David Nutt

Like restless children posing for a family portrait, electrons won’t hold still long enough to stay in any kind of fixed arrangement. Now, a Cornell-led collaboration has developed a way to stack two-dimensional semiconductors and trap electrons in a repeating pattern that forms a specific and long-hypothesized crystal. The team’s paper, “Correlated Insulating States at Fractional Fillings of Moiré Superlattices,” published Nov. 11 in Nature. The paper’s lead author is postdoctoral researcher Yang Xu. The project grew out of the shared lab of Kin Fai Mak, associate professor of physics in the... Read more
