Compositional modulation and surface stability in InGaP films: Understanding and controlling surface properties
We investigate the formation of compositional modulation and atomic ordering in InGaP films. Such bulk properties - as well as surface morphologies - present a strong dependence on growth parameters, mainly the V/III ratio. ...
Periodic study on the structural and electronic properties of bulk, oxidized and reduced SnO2(110) surfaces and the interaction with O-2
(Elsevier B.V., 2002-06-10)
The structural and electronic properties of bulk and both oxidized and reduced SnO2(110) surfaces as well as the adsorption process of O-2 on the reduced surface have been investigated by periodic DFT calculations at B3LYP ...
Minimal Lagrangian surfaces in the tangent bundle of a Riemannian surface
(ELSEVIER SCIENCE BV, 2011)
Given an oriented Riemannian surface (Sigma, g), its tangent bundle T Sigma enjoys a natural pseudo-Kahler structure, that is the combination of a complex structure 2, a pseudo-metric G with neutral signature and a symplectic ...
Subsurface bonding of hydrogen in transition metals: dependence on surface orientation
The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fcc and bcc structures. ...
Differential geometry of intersection curves in R(4) of three implicit surfaces
(Elsevier B.V., 2009-05-01)
We present algorithms for computing the differential geometry properties of intersection Curves of three implicit surfaces in R(4), using the implicit function theorem and generalizing the method of X. Ye and T. Maekawa ...
Structural and electronic properties of PbTiO3 slabs: a DFT periodic study
(Elsevier B.V., 2004-03-10)
Structural and electronic properties of the bulk and relaxed surfaces (TiO2 and PbO terminated) of cubic PbTiO3 are investigated by means of periodic quantum-mechanical calculations based on density functional theory. It ...
