Influence of Molecular Polarizability on the Active Layer of Organic Photovoltaic Cells: A case study of Poly(3-hexylthiophene)
(2013-05-23)
The complexity of the microstructure of the active layer in organic photo-voltaics (OPVs) poses a unique challenge in improving the efficiency of OPV devices. Molecular dynamics (MD) simulation provides a direct route ...
Simulation Of Carbon Nanotube Growth
(2013-05-28)
The basic understanding of the underlying techniques of growing Carbon Nanotubes (CNTs) with a specific chirality is still obscure and needs to be understood so as to properly harness its potentials. Using both Classical ...
Femtosecond Laser Surface Texturing of Materials for Various Applications
(2013-04-23)
Femtosecond lasers represent an electromagnetic field with field intensities approaching and even exceeding atomic binding field. When irradiated on a target, the material responses change from linear to nonlinear within ...
The Design of an On-Chip Silicon Photonic Diode
(2013-05-28)
This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on ...
Nonlinear Effects In Flow In Porous Duct
(2013-05-28)
In general, it is assumed in some non viscous flows that the flow velocity is constant at a cross-section. In this thesis, If we impose more realistic boundary conditions by, for example, introducing viscosity,and suction ...
Electro-Magnetic Duality, Magnetic monopoles and Topological Insulators
(2013-05-28)
The Maxwell equations of electrodynamics acquire an additional symmetry if one assumes the existence of hypothetical particles-magnetic monopoles, carrying a magnetic charge. The additional internal symmetry is the ...
Fundamentals of Laser Dynamics
(2013-04-23)
The thesis presents the modeling and simulation of three types of lasers namely; Semiconductor laser, Solid state laser and CO2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the ...
