Growth Mechanism And Interface Effects On Microstructure Of Perovskite-type Barium Titanate-based Epitaxial Films
(Materials Science & Engineering, 2012-07-25)
This work was motivated and focused on the growth mechanism, microstructures and interfaces of barium titanate, BaTiO₃ (BTO), based epitaxial thin films. Transimission electron microscopy (TEM), high resolution TEM (HRTEM), ...
Properties Of Concrete With Tire Derived Aggregate And Crumb Rubber As A Ligthweight Substitute For Mineral Aggregates In The Concrete Mix
(Materials Science & Engineering, 2012-07-25)
Scrap tires continue to be a nuisance to the environment and this research proposes one way of recycling them as a lightweight aggregate which can substitute for mineral aggregates in concrete. Aggregates derived from scrap ...
An Innovative Epitaxial Growth Method For Minimizing Dislocations In Thin-film Quantum-dot Optoelectronic And Photovoltaic Device Applications
(Materials Science & Engineering, 2012-07-25)
A new buffer layer method for epitaxial growth of lattice-mismatched semiconductor quantum-dots based p-i-n structures is presented. To our knowledge this is the first instance of a dislocation-reduction approach that ...
First-principles Studies On N-type And P-type Doping In Cuprous Oxide
(Materials Science & Engineering, 2012)
We have performed studies on n-type and p-type cuprous oxide with and without doping by first principles methods. Generalized Gradient Approximation (GGA) is used for the geometry optimization. The total energy and the ...
