Relationship between surface segregation and rapid propane electrical response in Cd-doped SnO2 nanornaterials
(ELSEVIER SCIENCE SA, 2008)
Controlling the surface properties of nanoparticles using ionic dopants prone to be surface segregated has emerged as an interesting tool for obtaining highly selective and sensitive sensors. In this work, the surface ...
ARXPS and DFT studies of thermally induced Pb surface segregation on Au/Cu alloys
(Elsevier Science, 2013-10)
Surface segregation of Pb has been studied using angle resolved X-ray Photoelectron Spectroscopy (ARXPS) and Density Functional Theory (DFT) modelling in a polycrystalline Au0.85Cu0.15 alloy. Au surface enrichment was found ...
Study of the influence of indium segregation on the optical properties of InGaAs/GaAs quantum wells via split-operator method
(A V S AMER INST PHYSICS, 2010)
In the case of quantum wells, the indium segregation leads to complex potential profiles that are hardly considered in the majority of the theoretical models. The authors demonstrated that the split-operator method is ...
Segregation trends of the metal alloys Mo-Re and Mo-Pt on HfO2: A first-principles study
(Amer Inst PhysicsMelvilleEUA, 2006)
Alloying and surface composition of model Pd-Ag films synthesized by electroless deposition
(Pergamon-Elsevier Science Ltd, 2012-04)
PdAg model films and real composite membranes were prepared by sequential electroless deposition on top of porous stainless steel supports. Their surface properties were investigated by X-ray photoelectron spectroscopy ...
Electrum, the gold–silver alloy, from the bulk scale to the nanoscale: synthesis, properties, and segregation rules

Poly(3-hexylthiophene): TIPS-pentacene blends aiming transistor applications
(2016-06-01)
Poly(3-hexylthiophene):6,13-bis(triisopropylsilylethynyl)-pentacene (P3HT:TP) blends with a ratio of 1:1 (wt/wt) were deposited via spin coating on anodized oxide (Al2O3). A phase separation of the compounds was observed, ...
Effect of manganese on grain boundary segregation of sulfur in iron
(Elsevier Science, 2007-05)
The ASED-MO theory was used to study the electronic effects of S and the S-Mn couple upon the chemical embrittlement of Fe grain boundaries. The results obtained for S alone in a model of grain boundary (GB) are consistent ...
