Group III-nitride semiconductors are well suited for the fabrication of devices including visible-ultraviolet light emitting diodes, high-temperature and high-frequency devices. The wurtzite III-nitride based heterostructures ...

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 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, ...

Group III-A nitrides (GaN, AlN, InN and alloys) are materials of considerable contemporary interest and currently enable a wide variety of optoelectronic and high-power, high-frequency electronic applications. All of these ...

This thesis aims at investigating size dependence of properties of nanostructures from the point of view of a general scaling theory that smoothly connects properties of the bulk to that of nanostructures. Two different ...

Lead based materials have shown to be important materials showing high piezoelectricity, colossal dielectric constant, ferroelectricity along with their good mechanical behaviour and resistance to corrosion. As a result, ...

TiO2 is a well-known and very attractive material owing to its chemical stability, biocompatibility, and remarkable electrical and optical properties. Indeed, it exhibits a high dielectric constant and resistivity, a high ...

Fuel cells offer the best solution to the imminent energy and environmental crisis staring at our face, urging the scientific community to overcome all the challenges faced by its effective commercialization. These harness ...

Depleting fossil fuels, increasing environmental concerned and looming energy crisis motivates researcher around the globe to explore some of the possible eco-friendly energy alternative resources. Among various available ...

The thesis consists of three parts of which Part 1 describes the investigations of borocarbonitrides. In this Part, Section 1.1 provides the synthesis and characterization of different compositions of borocarbonitrides. ...
