Abstract:

Polycrystalline materials are widely used for industrial applications. These materials are highly anisotropic with different responses under different loading conditions. This dissertation uses a crystal plasticity scheme in the finite element framework (CPFEM) to study deformation mechanisms in alumina, aluminium and stainless steel – all polycrystalline. Four research cases in this dissertation have been presented in the form of manuscripts for publication. When possible, modelling predictions have been compared against various experimental techniques such as Diffraction Contrast Tomography

Abstract:

This thesis investigates the crucial role of defects and disorder in determining the structural, electrical and magnetic properties of a few transition metal oxides. In solid state physics, crystallinity or the periodicity of lattice plays a very significant role. All the basic theories are formulated considering perfectly ordered crystalline materials because this simplifies the structural description. However in reality, the arrangement of atoms or molecules in most crystalline materials is not perfect and often interrupted by crystallographic defects disrupting the perfect crystalline order

However, the ionic conductivity of SrTiO3 is low comparing to YSZ. In general, space charge of grain boundaries (GBs) trapped oxygen ion to result low ionic conductivity. Based on previous studies, there is no evidence of space charge layers in low energy coincidence-site lattice ?? GBs which do not impede the

Abstract:

Polycrystalline materials are widely used in large area electronic devices such as flat panel x-ray image detectors, and solar cells due to their suitability to deposit over large area at low cost. The performance of polycrystalline-based flat panel detectors are showing encouraging results (good sensitivity, good resolution and acceptable dark current) and give possibility to replace existing x-ray film/screen cassette. Therefore large area polycrystalline based flat panel detectors have opened new clinical possibilities and the polycrystalline solar cells give the opportunity of manufacturin

Abstract:

The successful exfoliation of graphene in 2004 ushered in the era of 2D van der Waals materials, paving the way for a wide variety of applications in the field of electronics, optoelectronics, sensors, catalysis, flexible and wearable electronics. Chemical vapour deposition (CVD) is a low-cost, scalable technique which allows the direct and controllable synthesis of large-area uniform films of 2D materials for wafer-scale technologies. A major drawback of this technique lies in the polycrystalline nature of the films due to the inevitable presence of lattice point defects and extended line

Grain boundaries will cause the variation of threshold voltage in poly-Si TFTs. This thesis focuses on the effect of the locations of grain boundaries on the threshold voltage. New analytical models were developed. Base on the solution by two dimensional Poisson’s equation, lateral surface potential with a single grain boundary was obtain by assuming the grain boundary as a region with trapped charges.

Compositionally, colloidal suspensions consist of particles whose size ranges from a few nanometers to a few microns, dispersed in a solvent. A hallmark feature of these systems is that they exhibit Brownian motion, which makes them suitable for investigating statistical mechanical phenomena. Over the last fi

The experimental discovery of graphene in 2004 has opened up a new research field in the direction of atomically thin two-dimensional layered materials for exploration of many fundamental research problems and technological applications. The charge carriers in graphene are massless Dirac fermions due to which they exhibit absence of localization, thereby giving rise to huge intrinsic mobilities and ballistic transport even at room temperatures. But it was observed that the extrinsic disorder and intrinsic structural disorder can significantly influence the transport in graphene films. This the

Les travaux de recherche menés dans cette thèse de doctorat se sont focalisés sur la compréhension des interactions graphène-plasma dans le cas de l’exposition de graphène polycristallin à un plasma d’argon pouvant contenant du diborane (B2H6). Une attention particulière est portée sur la cinétique de génération de dommage dans un plasma d’argon pur. Ainsi dans le cas d’un plasma continu, l’absence de seuil en énergie pour la génération de dommage due à un bombardement ionique est mis en évidence. Ceci ne peut s’expliquer que par une gravure à deux étapes, facilitée par la densité ionique élev
