Effects Of Disorder On Physical Properties Of Selected Transition Metal Oxides
(2013-02-14)
Disorder in materials often brings in new and exotic physical properties along with it. It is thus very important to study different kinds of disorder and their implications on various material properties. In this thesis, ...
One Dimensional Transport And Prospects Of Structural Transitions In Ultrathin Metallic Wires
(2013-02-25)
This thesis reports transport in ultrathin single crystalline nanowires of gold (∼ 2nm). These nanowires were fabricated using an oriented attachment process whereby nanoparticles of appropriate dimensions join in a linear ...
Optical Tweezers To Probe And Manipulate Soft, Nano And Bio Systems
(2013-01-31)
Statistical physics in soft matter systems, physical properties of bio-inspired systems and the mechanical manipulations of nano-systems have been studied using optical tweezers to form the basis of this doctoral Thesis. ...
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 ...
