High-Throughput Exploration of Refractory High-Entropy Alloys for Strength and Plasticity
Stephen A. Giles, Hugh Shortt, Peter K. Liaw +1
Refractory high-entropy alloys (RHEAs) are compositionally complex materials which have been demonstrated to have the potential for exceptional strength at high operating temperatu…
Real Space Imaging of the Microscopic Origins of the Ultrahigh Dielectric Constant in Polycrystalline CaCu3Ti4O12
S. V. Kalinin, J. Shin, G. M. Veith +4
The origins of an ultrahigh dielectric constant in polycrystalline CaCu3Ti4O12 (CCTO) was studied using the combination of impedance spectroscopy, electron microscopy, and scanning…
AB Initio Studies of Electronic Excitations in Real Solids
Adolfo G. Eguiluz, Wei Ku
The first part of this article centers on the fact that key features of the dynamical response of weakly-correlated materials (the alkalis, Al), have been found experimentally to d…
Dynamical Response of Correlated Electrons in Solids Probed by Inelastic Scattering Experiments: An Ab Initio Theoretical Perspective
Adolfo G. Eguiluz, Wei Ku, James M. Sullivan
We present results of ab initio theoretical investigations of the excitation spectra of correlated electrons in metals (Al, K, and Li) and their interplay with inelastic scattering…
Ab Initio Evaluation of Plasmon Lifetimes in the Alkali Metals
Wei Ku, Adolfo G. Eguiluz
The anomalous plasmon linewidth dispersion (PLD) measured in K by vom Felde, Sprosser-Prou, and Fink (Phys. Rev. B 40, 10181 (1989)), has been attributed to strong dynamical electr…
