Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Adeline Crépieux, Emile Pangburn, Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll | Summary: We compute the (0-11) surface spectral function, the surface density of states (DOS), and the quasiparticle interference (QPI) patterns, both in the normal state and superconducting (SC) state of UTe$_2$. We consider […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll, Bin Hu, Xiaolong Liu | Summary: Although no known material definitely exhibits intrinsic topological superconductivity, where a spin-triplet electron pairing potential $Delta(k)$ has odd parity, UTe2 is now the leading candidate. Ideally, the parity of $Delta(k)$ might be […]
Kavli Affiliate: Katja C. Nowack | First 5 Authors: Ruiheng Bai, Aliakbar Sepehri, Yen-Lee Loh, Anne-Marie Valente-Feliciano, Anna Herr | Summary: We use scanning superconducting quantum interference device (SQUID) microscopy to image vortices in superconducting strips fabricated from NbTiN thin films. We repeatedly cool superconducting strips with different width in an applied magnetic field and […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee, Haoran Lu, Jorge L. Ramirez | 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 […]
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 […]

Poage, Bernardo Langa, Jr., Deepak Sapkota, Salva Salmani-Rezaie | Summary: The intersection of superconductivity and ferroelectricity hosts a wide range of exotic quantum phenomena. Here, we report on the observation of superconductivity in high-quality tin telluride films grown by molecular beam epitaxy. […]
Kavli Affiliate: Debdeep Jena | First 5 Authors: Maike Gremmel, Chandrashekhar Prakash Savant, Debaditya Bhattacharya, Georg Schönweger, Debdeep Jena | Summary: This study explores the influence of boron incorporation on the structural and electrical properties of ferroelectric Aluminum Scandium Nitride (Al_{1-x}Sc_xN ) thin films, focusing on leakage currents, wake-up effects, and imprint behavior. Al_{1-x}Sc_xN films […]
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 […]
