Ultrafast Response And Time Resolved Spectroscopy Of Carbon Nanotubes, Semiconductors And Rare-Earth Titanates Using Femtosecond Laser Pulses
(2013-10-21)
In this thesis, experimental studies are reported of ultrafast dynamics and third order optical nonlinear coefficients of carbon nanotubes, and time resolved coherent phonon dynamics of semiconductors and rare earth ...
Dynamics of Glass-Forming Liquids and Shear-Induced Grain Growth in Dense Colloidal Suspensions
(2018-06-19)
The work presented in this doctoral thesis employs colloidal suspensions to explore key open problems in condensed matter physics. Colloidal suspensions, along with gels, polymers, emulsions and liquid crystals belong to ...
Slow Dynamics In Complex Fluids : Confined Polymers And Soft Colloids
(2015-08-05)
The thesis describes the study of slow dynamics of confined polymers and
soft colloids. We study the finite size effect on the dynamics of glassy polymers
using newly developed interfacial microrheology technique. ...
Preparation and Optical Properties of Hybrid Assemblies of Metallic Gold Nanoparticles and Semi-Conducting CdSe Quantum Dots
(2018-04-16)
This thesis summarizes the methods of preparation and optical properties of hybrid assemblies of Au NPs and cadmium selenide (CdSe) QDs. First chap-ter deals with the literature survey and theoretical aspects of plasmonics ...
Thin Film Instabilities Mediated Self-Assembly of Polymer Grafted Nanoparticles
(2018-07-18)
After the advent of nanotechnology, self-assembly has become an active area of research, as it being one of the few efficient methods to generate ensembles of nanostructures. In this thesis, we present studies on two ...
Laser Beam Induced Conductance Modulations as a Potential Microprobe in the Investigation of Defects and Inhomogeneities in Bulk Si and PbS, HgCdTe Quantum Dot Heterostructures
(2018-05-18)
In this thesis, the strength of the LBIC system is enhanced in different aspects that includes its feasibility as a non-destructive characterization tool, the signal analysis and development of analytical solution to have ...
Confinement, Coarsening And Nonequilibrium Fluctuations In Glassy And Yielding Systems
(2016-02-17)
One of the most important and interesting unsolved problems of science is the nature of glassy dynamics and the glass transition. It is quite an old problem, and starting from the early20th century there have been many ...
