Monolayer MoS2-based heterostructure devices on Silicon and Flexible Substrates
This work presents a comprehensive study of MoS2-based field-effect transistors (FETs), investigating three key aspects: hysteresis effects, asymmetric I-V characteristics, and piezoelectric properties. Through an exploration ... -
The monopole-dimer model and eccentricities for Cartesian product of graphs
This thesis comprises two main parts. The details of the two parts are as follows: The first part of the thesis deals with the monopole-dimer model. The dimer (resp. monomer-dimer) model deals with weighted enumeration of ... -
Morphology and topology of cosmological fields during the Epoch of Reionization
In this thesis we have introduced a real space morphological tool, Contour Minkowski tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that the size and shape information of structures ... -
Mossbauer, Magnetization And Electrical Transport Studies On Iron Nanoparticles Embedded In The Carbon Matrix
(2009-08-19)This thesis deals with the studies of magnetization and electrical transport properties of iron nanoparticles embedded in the carbon matrix. The synthesis and characteristics of the nanoparticle systems studied, are also ... -
Mott-Hubbard Phenomena : Studies Within The Local Approximation
(2012-01-10)In this thesis we address a few such problems involving the microscopic theory of strongly correlated electrons using the d-tca or local approximation. The rest of this Chapter is organised as follows: we summarise the ... -
Multi-Axis Motion Measurement Systems Based on Optical Beam Deflection
Multi-axis motion measurement is indispensable for precision motion control, and characterization of dynamic response of mechanical structures. This work describes the development and applications of a 5-axis high bandwidth ... -
Multi-Dimensional Solid State NMR - Methods Development and Application to Materials
In recent years, the scope of application of solid-state NMR to different areas has been witnessing a significant increase. Primarily, this is due to the possibility of routine use of proton NMR spectroscopy at ultrafast ... -
Multi-Nuclear and Multiple-Quantum NMR in the Solid-State : Methods and Applications
(2018-01-03)NMR spectroscopy is a very powerful technique for the characterization of structure and dynamics of a variety of systems starting from small organic molecules to large biological macromolecules. In solids, the study of ... -
Multi-scale Modelling of HLA Diversity and Its Effect on Cytotoxic Immune Responses in Influenza H1N1 Infection
(2018-06-06)Cytotoxic T-lymphocytes (CTLs) are important components of the adaptive immune system and function by scanning the intracellular environment so as to detect and de-stroy infected cells. CTL responses play a major role in ... -
Multiband Modelling and Radio Observations of Gamma Ray Burst Afterglows
The widely popular and successful standard fireball model for Gamma Ray Burst (GRB) afterglows is based on ultra-relativistic external shocks sweeping up matter around the explosion site to accelerate electrons up to GOV ... -
Multicarrier Effects In High Pulsed Magnetic Field Transport And Optical Properties Of Mercury Cadmium Telluride
(2011-01-17)This thesis on multicarrier effects in the magnetotransport and optical properties of Mercury Cadmium Telluride (MCT or HgCdTe) covers mainly: design, construction and calibration of a 12T 4K and 19T 77K pulsed high magnetic ... -
Multidimensional Multicolor Image Reconstruction Techniques for Fluorescence Microscopy
(2018-06-26)Fluorescence microscopy is an indispensable tool in the areas of cell biology, histology and material science as it enables non-invasive observation of specimen in their natural environment. The main advantage of fluorescence ... -
Multiphase gas in the baryon cycle: from jellyfish galaxies to turbulent galactic outflows
The formation and evolution of galaxies are shaped not only by gravity but also by the complex behaviour of gas—the dominant baryonic component within and around galaxies. This gas spans a wide range of temperatures, ... -
The multiphase interstellar medium: A study of various physical and kinematical properties
Interstellar medium (ISM) is the relatively empty space in between the stars. It has different phases, like, neutral, molecular, and ionized. Neutral interstellar medium, which is pervaded all over the galaxy, is sometimes ... -
Multiple Stable States and Abrupt Transitions in Spatial Ecosystems
Ecosystems can exhibit multiple stable states at similar external conditions. Such systems shift from one stable state to another abruptly and discontinuously, when they cross certain threshold parameters. Some examples ... -
Multiscale Modeling of Molecular Sieve Membranes
Gases permeating through nanopores experience selective adsorption with sub-diffusive dynamics. In this work we investigate how the physicochemical properties of nanoporous membranes influence adsorption dynamics of gases, ... -
A Multiscale Modeling Study of Iron Homeostasis in Mycrobacterium Tuberculosis
