Soft X-ray Multilayers As Polarizing Elements : Fabrication, And Studies Of Surfaces And Interfaces
(2010-03-09)
The exploitation of the soft x-ray/extreme ultra-violet (EUV) region of the electromagnetic spectrum is possible mainly due to the development of multilayer (ML) mirrors. This region of the electromagnetic spectrum offers ...
Thin Films Of A Carbonaceous Copper Oxide, Li Doped Cobalt Oxide And Li At Nanometric Dimension : Synthesis Through CVD, Solgel And Electromagnetic Irradiation And Characterisation
(2009-09-14)
Thin film nanostructures may be defined as assemblies, arrays, or randomly distributed nanoparticles, nanowires, or nanotubes, which together form a layer of materials supported on a substrate surface. Because such ...
Investigations Into The Microstructure-Property Correlation In Doped And Undoped Giant Dielectric Constant Material CaCu3Ti4O12
(2010-05-24)
High dielectric constant materials are of technological importance as they lead to the miniaturization of the electronic devices. In this context, the observation of anomalously high dielectric constant (>104) in the ...
Investigations Into The Synthesis, Structural And Dielectric Properties Concerning The Relaxor Behavior Of n=2 Members Of The Aurivillius Family Of Oxides
(2010-05-21)
Relaxor ferroelectrics have been a subject of intense research owing to their interesting physical properties such as high dielectric constant and giant electro-striction. Unlike the conventional lead based relaxors, the ...
Studies On Pure And Modified Antiferroelectric PbZrO3 Thin Films
(2010-04-06)
Metal oxides crystallized in perovskite structure are generally modified in two different ways. According to the general structural formula ABO3, the two ways are A-site modification and B-site modification. The primary ...
Dynamical Approach To The Protevin-Le Chatelier Effect
(Indian Institute of Science, 2006-06-07)
Materials when subjected to deformation exhibit unstable plastic flow beyond the elastic limit. In certain range of temperature and strain rates many solid state solutions, both interstitial as well as substitutional, ...
Dielectric Titanate Ceramics : Contributions From Uncommon Substituents And Microstructural Modifications
(2009-03-02)
This thesis deals with the investigations on the dielectric properties of polycrystalline ceramics having uncommon substitutions in barium titanate and other related phases of BaTiO3-CaTiO3, MgTiO3-CaTiO3 and MgTiO3-BaTiO3 ...
Stress and Microstructural Evolution During the Growth of Transition Metal Oxide Thin Films by PVD
(2018-05-23)
System on Chip (SoC) and System in Package (SiP) are two electronic technologies that involve integrating multiple functionalities onto a single platform. When the platform is a single wafer, as in SOC, it requires the ...
