Plasmon-induced hot carriers from interband and intraband transitions in large noble metal nanoparticles
Hanwen Jin, Juhan Matthias Kahk, Dimitrios A. Papaconstantopoulos +2
Hot electrons generated from the decay of localized surface plasmons in metallic nanostructures have the potential to transform photocatalysis, photodetection and other optoelectro…
Possible High-Temperature Superconductivity in Hygrogenated Fluorine
D. A. Papaconstantopoulos
Recent computational studies confirmed by experiment have established the occurrence of superconducting temperatures, , near 200 K when the pressure is close to 200 GPa in the…
Cubic HS around 200 GPa: an atomic hydrogen superconductor stabilized by sulfur
D. A. Papaconstantopoulos, B. M. Klein, M. J. Mehl +1
The multiple scattering-based theory of Gaspari and Gyorffy for the electron-ion matrix element in close packed metals is applied to Im-3m H3S, which has been predicted by Duan {\i…
Tight-Binding Study of Boron Structures
Joseph W. McGrady, Dimitrios A. Papaconstantopoulos, Michael J. Mehl
We have performed Linearized Augmented Plane Wave (LAPW) calculations for five crystal structures (alpha, dhcp, sc, fcc, bcc) of Boron which we then fitted to a non-orthogonal tigh…
A first-principles study of the electronic structure of Iron-Selenium; Implications for electron-phonon superconductivity
Alexander P. Koufos, Dimitrios A. Papaconstantopoulos, Michael J. Mehl
We have performed density functional theory (DFT) calculations using the linearized augmented plane wave method (LAPW) with the local density approximation (LDA) functional to stud…
Electronic structure and superconductivity of Europium
Lane W. Nixon, D. A. Papaconstantopoulos
We have calculated the electronic structure of Eu for the bcc, hcp, and fcc crystal structures for volumes near equilibrium up to a calculated 90 GPa pressure using the augmented-p…
