The work carried out as a part of this thesis has been focussed on understanding different aspects of the chemical vapor deposition process namely, ALD / MOCVD. A large part of the thesis is aimed at solving the problem ...
Vapour Pressure Studies Of Precursors And Atomic Layer Deposition Of Titanium Oxides
(2010-07-16)
This thesis describes the deposition of thin films of titanium oxide and Magnéli phases of titanium oxide by atomic layer deposition (ALD) using a novel β-ketoesterate precursor. Titanium oxide is a promising candidate for ...
Studies on Effect of Defect Doping and Additives on Cr2O3 and SnO2 Based Metal Oxide Semiconductor Gas Sensors
(2018-03-09)
Metal Oxide (MO)semiconductors are one of the most widely used materials in commercial gas sensor devices. The basic principle of chemoresistive gas sensor operation stems on the high sensitivity of electrical resistance ...
Physicochemical Characterization and Gas Sensing Studies of Cr1-xFexNbO4 and Application of Principal Component Analysis
(2018-03-01)
Monitoring the working environment of laboratories and industries for pollutants is of primary concern to ensure the healthiness of working personnel. Semiconducting metal oxides (SMOs) are sensitive to the gas ambience ...
Tuning Zinc Oxide Layers Towards White Light Emission
(2014-06-09)
White light emitting diodes (LED) have drawn increasing attention due to their low energy consumption, high efficiency and potential to become primary lighting source by replacing conventional light sources. White light ...

(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 ...
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 ...
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 ...
