Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Maciej W. Olszewski, Maciej W. Olszewski, , , | Summary: Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally been avoided for making high-quality superconducting resonator devices. In this article, we […]

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Harikrishnan KP, Varun Harbola, Jaehong Choi, Kevin J. Crust, Yu-Tsun Shao | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect […]

Fuchs | First 5 Authors: Harikrishnan KP, Harikrishnan KP, , , | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect couples strain gradients to electric […]

Al_{1-x}Sc_xN films […]

Kavli Affiliate: Christopher Ober | First 5 Authors: Matthias Mayr, Alexander Heinlein, Christian Glusa, Siva Rajamanickam, Maarten Arnst | Summary: Trilinos is a community-developed, open-source software framework that facilitates building large-scale, complex, multiscale, multiphysics simulation code bases for scientific and engineering problems. Since the Trilinos framework has undergone substantial changes to support new applications and […]

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Yilin Evan Li, Harikrishnan KP, Haidong Lu, Rachel A. Steinhardt, Megan E. Holtz | Summary: Ultrathin ferroelectric films with out-of-plane polarization and high Curie temperatures are key to miniaturizing electronic devices. Most ferroelectrics employed in devices are proper ferroelectrics, where spontaneous polarization is the primary order […]

Kavli Affiliate: Zhiting Tian | First 5 Authors: Yeryun Cheon, Mehrdad T. Kiani, Yi-Hsin Tu, Sushant Kumar, Nghiep Khoan Duong | Summary: Ongoing demands for smaller and more energy efficient electronic devices necessitate alternative interconnect materials with lower electrical resistivity at reduced dimensions. Despite the emergence of many promising candidates, synthesizing high quality nanostructures remains […]

Kavli Affiliate: Katja C. Nowack | First 5 Authors: George M. Ferguson, Run Xiao, Anthony R. Richardella, Austin Kaczmarek, Nitin Samarth | Summary: The creation of topologically non-trivial matter across electronic, mechanical, cold-atom, and photonic platforms is advancing rapidly, yet understanding the breakdown of topological protection remains a major challenge. In this work, we use […]

Kavli Affiliate: Grace Xing | First 5 Authors: Chandrashekhar Savant, Thai-Son Nguyen, Kazuki Nomoto, Saurabh Vishwakarma, Siyuan Ma | Summary: We report a polarization-induced 2D electron gas (2DEG) at an epitaxial AlBN/GaN heterojunction grown on a SiC substrate. Using this 2DEG in a long conducting channel, we realize ultra-thin barrier AlBN/GaN high electron mobility transistors […]
