The role of nitrogen related defects in high-k dielectric oxides: Density functional studies
J. L. Gavartin, A. S. Foster, G. I. Bersuker +1
Using ab initio density functional total energy and molecular dynamics simulations, we study the effects of various forms of nitrogen post deposition anneal (PDA) on the electric p…
Interactions Mediated by Surface States: From Pairs and Trios to Adchains and Ordered Overlayers
Per Hyldgaard, T. L. Einstein
Since metallic surface states on (111) noble metals are free-electron like, their propagators can be evaluated analytically. Since they are well-screened, one can use simple tight-…
Barrier formation at metal/organic interfaces: dipole formation and the Charge Neutrality Level
H. Vazquez, F. Flores, R. Oszwaldowski +3
The barrier formation for metal/organic semiconductor interfaces is analyzed within the Induced Density of Interface States (IDIS) model. Using weak chemisorption theory, we calcul…
A Coupled Equations Model for Epitaxial Growth on Textured Surfaces
A. Ballestad, T. Tiedje, J. H. Schmid +2
We have developed a continuum model that explains the complex surface shapes observed in epitaxial regrowth on micron scale gratings. This model describes the dependence of the sur…
