Visualizing the breakdown of the quantum anomalous Hall effect

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 […]

Epitaxial high-K AlBN barrier GaN HEMTs

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 […]

Growth and characterization of single crystal cubic TaN and hexagonal Ta$_2$N films on c-plane Sapphire

Kavli Affiliate: Grace Xing | First 5 Authors: Anand Ithepalli, Amit Rohan Rajapurohita, Arjan Singh, Rishabh Singh, John Wright | Summary: Two single crystal phases of tantalum nitride were stabilized on c-plane sapphire using molecular beam epitaxy. The phases were identified to be $delta$-TaN with a rocksalt cubic structure and $gamma$-Ta$_2$N with a hexagonal structure. […]

Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO2 on Al2O3 and LaAlO3

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Anna Scheid, Tobias Heil, Y. Eren Suyolcu, Qi song, Niklas Enderlein | Summary: Delafossites, comprised of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significant promise for various applications, but their exploitation hinges on the successful […]

Violation of Pauli Limit at KTaO3(110) Interfaces

Kavli Affiliate: David A. Muller | First 5 Authors: Samuel J. Poage, Xueshi Gao, Merve Baksi, Salva Salmani-Rezaie, David A. Muller | Summary: The superconducting order parameter at the KTaO3 interfaces and its dependence on interface orientation remains a subject of debate. The superconductivity at these interfaces exhibits strong resilience against in-plane magnetic field and […]

Unveiling a Hidden Percolation Transition in Monitored Clifford Circuits: Inroads from ZX-Calculus

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Einat Buznach, Debanjan Chowdhury, Jonathan Ruhman, , | Summary: We revisit the measurement-induced phase transition (MPT) in Clifford circuits, which are both classically simulable and exhibit critical behavior widely believed to be distinct from classical percolation theory, using ZX-calculus. We analyze the MPT in a dynamical model […]

Shubnikov-de Haas oscillations in coherently strained AlN/GaN/AlN quantum wells on bulk AlN substrates

Kavli Affiliate: Grace Xing | First 5 Authors: Yu-Hsin Chen, Jimy Encomendero, Huili Grace Xing, Debdeep Jena, | Summary: We report the observation of Shubnikov-de Haas (SdH) oscillations in coherently strained, low-dislocation AlN/GaN/AlN quantum wells (QWs), including both undoped and $delta$-doped structures. SdH measurements reveal a single subband occupation in the undoped GaN QW and […]
