The year 2011 has witnessed the completion of 100 years of discovery of superconductivity. It was discovered in the year 1911 by H. K. Onnes in mercury while measuring its resistivity at low temperatures. He observed a ...

The thesis consists of seven chapters of which the first chapter provides a brief overview of graphene. Chapter 2 deals with the synthesis and characterization of graphene. When graphene research was initiated in our ...

Semiconductors have revolutionised many aspects of life over the past 50 years. Techniques which have led to low cost, high density processing of silicon have resulted in silicon integrated circuits becoming ubiquitous ...

The prefix nano in ‘nanoscience’ means a billionth (1 × 10-9 ). It deals with various aspects of matter, having dimensions of the order of a billionth of a meter (1 nm). At the nanoscale, the fundamental properties of ...

Hybrid materials derived from organic and inorganic components are receiving enormous attention owing to their applications in the fields of biology, energy, catalysis, reinforcements, etc. 1 These materials are broadly ...

The present thesis uses two optical probes, namely, Raman and Brillouin spectroscopy to study the physical properties of material. In order to understand the systeM.S. we have used the two thermodynamic quantities, pressure ...

At the onset of twenty first century, molecular spectroscopy has been rejuvenated by the advances in various fields like optical instrumentation, nanoscience and biotechnology. By employing various spectroscopic techniques, ...

Nanoscience involves the study of properties and phenomena on the scale of 1- 100 nm (1 nm = 10−9 m). Nanotechnology involves the design, fabrication and application of nanomaterials, and the fundamental understanding ...

Since the development of the two-cylinder steam engine by James Watt in the 1760s, human-kind has experienced three industrial revolutions [1]. The first industrial revolution, as represented by the appearance of ...

Many interesting and counter intuitive properties have been predicted over decades in low-dimensional systems. i.e. systems. confined to less than three dimensions. In this thesis, we have investigated the electronic ...
