Researchers revealed atomic-level correlated motion of water molecules at the crucial picosecond timescale to evaluate the dynamic nature of the liquid by using coherent X-ray scattering. This research could revolutionize understanding and control
Novel defect control and chemical doping strategies are discovered to suppress the detrimental bulk conduction in the antiferromagnetic topological insulators MnBi2Te4 and MnBi4Te7. The results of this wo
Researchers proposed a new strategy to explore various quantum phases and used it to predict the first room-temperature quantum anomalous Hall effect in a 2D post-transition metal system.
Neutron scattering experiments revealed how emergent multi-spin clusters suppress conventional magnetic ordering in a frustrated pyrochlore magnet
Led by ORNL and the University of Tennessee, Knoxville, a study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat.
Researchers proposed a new concept for transient negative capacitance (NC) based on inverse polarization switching against the electric field in layered van der Waals (vdW) ferrielectric CuInP2S6.
Researchers at ORNL used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional tools.
Researchers have shown that scanning transmission electron microscopy (STEM) can be used to learn causal mechanisms – rather than mere correlations – of atomistic behavior in ferroelectric perovskite across
Neutron scattering from photovoltaic methylammonium lead iodide reveals a giant effect of isotopic substitution on phonons due to coupling with molecule dynamics that results in enhanced thermal resistivity and increased hot-carrier cooling times.
