Effect of uniaxial compressive stress on polarization switching and domain wall formation in tetragonal phase BaTiO3 via machine learning potential

This study utilizes a machine learning potential to demonstrate that uniaxial compressive stress significantly influences polarization switching and domain wall evolution in tetragonal BaTiO3, revealing a critical threshold of approximately 120 MPa for 90-degree switching, stress-induced reductions in remnant polarization and coercive field, and the emergence of double hysteresis loops at 80 MPa.

Controlling Mixed Mo/MoS2_2 Domains on Si by Molecular Beam Epitaxy for the Hydrogen Evolution Reaction

This study demonstrates that controlling sulfur stoichiometry and growth kinetics during molecular beam epitaxy on silicon substrates enables the creation of defect-engineered Mo/MoS2_2 heterostructures with residual metallic Mo and sulfur vacancies, which significantly enhance hydrogen evolution reaction performance by activating inert basal planes and improving charge transfer compared to stoichiometric films.

First principles electric field gradients at A and B site cations across the NaRTiO4 Ruddlesden Popper series

This study employs first-principles calculations to map the structural, electronic, and hyperfine properties of the NaRTiO4_4 Ruddlesden-Popper series, revealing how ionic radius dictates the competition between ground-state symmetries and establishing Electric Field Gradient signatures as a sensitive probe for resolving these structures via experimental techniques like NMR and PAC.

Electrically tunable orbital coupling and quantum light emission from O-band quantum dot molecules

This paper demonstrates electrically tunable orbital coupling and high-quality single-photon emission at telecom O-band wavelengths (~1300 nm) from individual InAs/InGaAs quantum dot molecules, characterized by pronounced excitonic anticrossings and a second-order correlation function of g(2)(0) = 0.017(2).

Singing Materials: Initial experiments in applying sonification to phonon spectra

This paper introduces \texttt{SingingMaterials}, a modular Python package that sonifies phonon density-of-states data from the Materials Project using three distinct approaches, and validates through a user study that auditory representations can effectively help listeners distinguish differences in material properties.
