Quantifying the Relationship Between Strain and Bandgap in Thin GaSe
Lottie L. Murray, Eric Herrmann, Igor Evangelista +3
We present a rigorous analysis that combines theory, simulation, and experimental measurements to quantify the relationship between strain and bandgap in two dimensional gallium se…
Quantum geometric origins of the orbital degrees of freedom of hybrid bosonic quasiparticles in magnetic systems
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
The orbital degree of freedom has recently attracted significant attention due to the novel phenomena it enables in condensed matter systems. However, the interpretation of the orb…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
Tunable magnon band topology and magnon orbital Nernst effect in noncollinear antiferromagnets
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
We theoretically investigate the intrinsic magnon orbital Nernst effect (ONE) in noncollinear antiferromagnets with Kagomé spin systems. Our analysis reveals that an externally app…
Weyl semimetal phases and intrinsic spin-Hall conductivity in SbAs ordered alloys
Muhammad Zubair, Dai Q. Ho, Duy Quang To +2
Using density functional theory calculations we investigated possible Weyl semimetal (WSM) phases in antimony arsenide ordered alloys Sb1-xAsx (x=0, 1/6, 1/3, 1/2, 2/3, 5/6, 1). We…
Band-gap reduction and band alignments of dilute bismide III--V alloys
Abdul Saboor, Shoaib Khalid, Anderson Janotti
Adding a few atomic percent of Bi to III--V semiconductors leads to significant changes in their electronic structure and optical properties. Bismuth substitution on the pnictogen…
