Resolving the Kagome Origin of the Strange Metallicity in NiIn
Jean C. Souza, Moshe Haim, Ambikesh Gupta +15
Strong correlations promote singular properties such as strange metallicity, which shows considerable commonality across quantum materials platforms. Understanding the mechanism fo…
Reconfigurable Strain Gradient Polarity in Crystalline Oxide Nanomembranes for Controlled Bending of Functional Materials
Tiffany C. Wang, Minyong Han, Varun Harbola +1
We report the fabrication and mechanical characterization of a "bubble" geometry for accessing local strain gradients using freestanding, single-crystalline manganite nanomembranes…
Dirac fermions and flat bands in the ideal kagome metal FeSn
Mingu Kang, Linda Ye, Shiang Fang +19
The kagome lattice based on 3d transition metals is a versatile platform for novel topological phases hosting symmetry-protected electronic excitations and exotic magnetic ground s…
Atomically thin p-n junctions with van der Waals heterointerfaces
Chul-Ho Lee, Gwan-Hyoung Lee, Arend M. van der Zande +10
Semiconductor p-n junctions are essential building blocks for modern electronics and optoelectronics. In conventional semiconductors, a p-n junction produces depletion regions of f…
Band engineering of a magnetic thin film rare earth monopnictide
Hisashi Inoue, Minyong Han, Mengli Hu +3
Realizing quantum materials in few atomic layer morphologies is a key to both observing and controlling a wide variety of exotic quantum phenomena. This includes topological electr…
Molecular Beam Epitaxy Growth of Antiferromagnetic Kagome Metal FeSn
Hisashi Inoue, Minyong Han, Linda Ye +2
FeSn is a room-temperature antiferromagnet expected to host Dirac fermions in its electronic structure. The interplay of magnetic degree of freedom and the Dirac fermions makes FeS…
