Facile and Process Compatible Growth of High-k Gate Dielectric Materials (TiO2, ZrO2 and HfO2) on Si and the Investigation of these Oxides and their Interfaces by Deep Level Transient Spectroscopy
(2018-07-14)
The continuous downscaling has enforced the device size and oxide thickness to few nanometers. After serving for several decades as an excellent gate oxide layer in complementary metal oxide semiconductor (CMOS) devices, ...
Experiments on the 852 nm D2 Line of 133Cs with a Diode Laser System and their use in Measurement of the Permanent Electric Dipole Moment of the Electron
(2018-07-14)
We give a brief introduction to atomic physics and the motivation behind our experiments in the first chapter. The electron’s electric dipole moment is an interesting quantity which is yet to be measured. In the 3rd Chapter, ...
Electric, Magnetic and Magnetocaloric Studies of Magnetoelectric GdMnO3 and Gd0.5Sr0.5MnO3 Single Crystals
(2018-05-10)
After the prediction of magnetoelectric effect in Cr2O3, in early 1960's, D. Asrov became the first to experimentally verify this phenomenon. After the pioneering work on magnetoelectric materials in 1960's and 1970's, the ...
Polymer Assisted Dispersion of Carbon Nanotubes (CNTs) and Structure, Electronic Properties of CNT - Polymer Composite
(2018-05-21)
Carbon nanotubes possess various unique and interesting properties. They have very high thermal and electrical conductivities, high stiffness, mechanical strength, and optical properties. Due to these properties, CNTs are ...
Precision Measurements of the Radio Background at Long Wavelengths
(2018-05-09)
The study of continuum sky background spectrum at low radio frequencies has achieved specific importance in present day observational cosmology . At these low frequencies the sky continuum is contributed by the extragalactic ...
Investigations and Stabilization of Vortex States in Cobalt and Permalloy Nanorings in Contact with Nanowires
(2018-07-09)
Magnetic nanorings are the object of increasing scientific interest because they possess the vortex (stray field free) state which ensures lower magnetostatic interactions between adjacent ring elements in high packing ...
Studies of Ultracold Bosons in Optical Lattices using Strong-Coupling Expansions
(2018-06-14)
Cold bosonic atoms trapped in optical lattices formed by standing wave interference patterns of multiple laser beams constitute excellent emulators of models of strongly correlated quantum systems of bosons. In this thesis, ...
Driven Granular and Soft-matter : Fluctuation Relations, Flocking and Oscillatory Sedimentation
(2018-06-11)
Active matter refers to systems driven out of thermal equilibrium by the uptake and dissipation of energy directly at the level of the individual constituents, which then undergo systematic movement in a direction decided ...
Topology and Quantum Phases of Low Dimensional Fermionic Systems
(2018-05-21)
In this thesis, we study quantum phase transitions and topological phases in low dimensional fermionic systems. In the first part, we study quantum phase transitions and the nature of currents in one-dimensional systems, ...
Study of Evolved Stellar Populations in the Magellanic Clouds
(2018-06-05)
The Magellanic Clouds (MCs) consist of a pair of galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which are located at a distance of 50 kpc and 60 kpc, with stellar masses of 1010 M and 109 ...
