Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures
Saeed S. I. Almishal, Sai Venkata Gayathri Ayyagari, Aaron Pearre +9
High-entropy oxide (HEO) thin films uniquely superimpose exceptional chemical disorder with exceptional crystalline quality and coherence - an intersection we term anomalous crysta…
Tuning the low-energy band structure in twisted bilayer WSe2
T. -H. -Y. Vu, O. J. Clark, N. H. Jo +21
Tuning the electronic structures of two-dimensional (2D) material-based heterostructures is of crucial importance for their use in functional next-generation electronics. Here, thr…
Defect Control via Cu Enrichment Enhances Multifunctional Properties in the Polar Semiconductor Cu1+xMn1-ySiTe3
Subrata Ghosh, Yu Liu, Saugata Sarker +15
Polar materials have recently attracted significant interest due to their rich multifunctional properties. The chalcogenide polar semiconductor Cu1-xMn1+ySiTe3 (Cu-deficient) is an…
Coexistence of ferromagnetism and ferroelectricity in the van der Waals multiferroic CuIn0.2V0.8P2S6
Subrata Ghosh, Rosalin Mohanty, Yuwei Sun +6
Two-dimensional (2D) van der Waals (vdW) multiferroics have emerged as a promising platform for next-generation multifunctional devices. Although recent studies have demonstrated t…
Imaging topological polar structures in marginally twisted 2D semiconductors
Thi-Hai-Yen Vu, Daniel Bennett, Gayani Nadeera Pallewella +16
Moire superlattices formed in van der Waals heterostructures due to twisting, lattice mismatch and strain present an opportunity for creating novel metamaterials with unique proper…
Ramp Josephson junctions of Al/Ti/Sr2RuO4: Observation of single-domain quantum oscillations and the detection of chiral edge current
Zixuan Li, Yiqun Alex Ying, Brian M. Zakrzewski +4
The determination of how the phase of the superconducting order parameter in a superconductor varies with the spatial direction, which can be done only through the Josephson-effect…
