An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...

Recientemente, se ha comenzado a utilizar el formalismo superespacial para unificar las descripciones de los miembros de familias de estructuras de composición flexible, en un único modelo estructural. Estas estructuras ...

We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical ...

We propose a generalized gradient approximation (GGA) for the angle- and system-averaged exchange-correlation hole of a many-electron system. This hole, which satisfies known exact constraints, recovers the Perdew-Burke-Ernzerhof ...

First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ...

Los moléculas mesógenas con forma de banana (bent-core) dan lugar a nuevas fases cristal líquido con diversas funcionalidades de interés en aplicaciones tecnológicas. En esta tesis se han estudiado y caracterizado nuevos ...

Advanced gamma-TiAl based intermetallics Mo-bearing have been developed to obtain the fine-grained microstructure required for superplastic deformation to be used during further processing. In the present work we have ...

Dentro del marco industrial mundial y del País Vasco en particular el sector metalúrgico ha tenido y tiene un peso muy importante. En muchos de los materiales utilizados es vital conocer las pérdidas de calor por radiación, ...

KIMERA is a scientific tool for the study of mineral dissolution. It implements a reversible Kinetic Monte Carlo (KMC) method to study the time evolution of a dissolving system, obtaining the dissolution rate and information ...

Carrier doping by the electric field effect has emerged as an ideal route for monitoring many-body physics in two-dimensional materials where the Fermi level is tuned so that the strength of the interactions can also be ...
