Group III Nitride/p-Silicon Heterojunctions By Plasma Assisted Molecular Beam Epitaxy
(2015-07-24)
The present work focuses on the growth and characterizations of GaN and InN layers and nanostructures on p-Si(100) and p-Si(111) substrates by plasma-assisted molecular beam epitaxy and the studies of GaN/p-Si and InN/p-Si ...
Study Of Relaxor Ferroelectric PMN-PT Thin Films For Energy Harvesting Applications
(2015-08-06)
The present research work mainly focuses on the fabrication of 0.85PMN-0.15PT thin film relaxor ferroelectrics for energy harvesting applications.
Chapter 1 gives a brief review about why energy harvesting is required ...
Graphene Nanostructures : A Theoretical Study Of Electronic, Magnetic And Structural Properties
(2014-09-26)
Graphene is a single layer of carbon atoms arranged in honeycomb lattice. Over a long period of time it was treated as a hypothetical material to understand the properties of other allotropes of carbon, such as graphite, ...
Thermal Expansion And Related Studies In Cordierite Ceramics And Relaxor Ferroelectrics
(2013-07-02)
The following investigations have been carried out in this thesis
1)Cordierite is already well known for its low thermal expansion behaviour. Chemical substitutions at various octahedral and tetrahedral sites have been ...
Thin Film Semiconducting Metal Oxides By Nebulized Spray Pyrolysis And MOCVD, For Gas-Sensing Applications
(2013-04-19)
The atmosphere we live in contains various kinds of chemical species, natural and artificial, some of which are vital to our life, while many others are more or less harmful. The vital gases like oxygen, humidity have to ...
Multifunctionalities Of Ceramics And Glass Nanocrystal Composites Of V2O5 Doped Aurivillius Family Of Ferroelectric Oxides
(2011-09-19)
In recent years bismuth-based, layer-structured perovskites such as SrBi2Nb2O9 (SBN) and SrBi2Ta2O9 (SBT) have been investigated extensively, because of their potential use in ferroelectric random access memories (FeRAMs). ...
Borate Based Glasses, Transparent Glass-Microcrystal Composites And Their Physical Properties
(2013-04-30)
Transparent glasses embedded with ferroelectric/nonlinear optic crystallites have been in increasing demand as these exhibit promising physical properties. These could be fabricated in large sizes and shapes with high ...
