Mechanical control of competing magnetic order in crystalline MnPtGa membranes
R Rawat, F Fei, T Samanta +5
MnPtGa hosts competing magnetic states, including ferromagnetic, canted antiferromagnetic, and spin density wave (SDW) order in the centrosymmetric structure, while a re…
A First-Principles Multiscale Framework for Topological Superconductivity
Christopher L. Jacobs, Baishali Mandal, Taehwan Jung +4
A microscopic understanding of topological superconductivity (TSC) in real materials requires a materials-informed approach that integrates first-principles electronic structure, s…
Acoustic Phonon Dynamics in Co-Doped BaFeAs Thin Film
Alexander Bartenev, Roman Kolodka, Larry Theran +5
Pump-probe reflectivity reveals coherent acoustic oscillations at 33 and 8.2 GHz in a Ba(FeCo)As thin film. The acoustic response was analyzed using a mod…
Fit-Free Optical Determination of Electronic Thermalization Time in Nematic Iron-Based Superconductors
Alexander Bartenev, Roman Kolodka, Ki-Tae Eom +6
We present a nematic response function model (NRFM) for fit-free direct extraction of the characteristic time of ultrafast electronic thermalization in iron-based superconductors,…
Adsorption-Controlled Epitaxy and Twin Control of -GaSe on GaAs (111)B
Joshua Eickhoff, Wendy L. Sarney, Sina Najmaei +2
The III-Se layered semiconductors, including InSe and GaSe, are promising optoelectronic materials due to their relatively high electron mobilities at room temperature, nonlinear o…
Epitaxial stabilization of magnetic GdAuSb/LaAuSb superlattices
Patrick J. Strohbeen, Soohyun Im, Tamalika Samanta +7
We report the epitaxial stabilization of GdAuSb films and GdAuSb/LaAuSb superlattices via molecular beam epitaxy on (0001)-oriented AlO substrates. GdAuSb crystallize i…
Strain patterning of flexomagnetism
Tamalika Samanta, Zachary T. LaDuca, An-Hsi Chen +15
Flexomagnetism, the coupling of magnetic ordering to strain gradients, provides access to novel symmetry-broken magnetic phases that cannot be accessed via uniform strain. However,…
Remote epitaxial frustration stabilizes a correlated interfacial state
Taehwan Jung, Nicholas Hagopian, Anshu Sirohi +7
Remote epitaxy exploits substrate interactions transmitted across atomically thin materials to replicate substrate crystal structure. Here we show that competition among graphene-,…
How transparent is graphene? A surface science perspective on remote epitaxy
Zach LaDuca, Anshu Sirohi, Quinn Campbell +1
Remote epitaxy is the synthesis of a single crystalline film on a graphene-covered substrate, where the film adopts epitaxial registry to the substrate as if the graphene is transp…
Analytical model for the remote epitaxial potential
Jason K Kawasaki, Quinn T Campbell
We propose an analytical model for the remote bonding potential of the substrate that permeates through graphene during remote epitaxy. Our model, based on a Morse interatomic pote…
