Abstract:

Many-Body Perturbation Theory is put to test as a method for reliable calculations of the electron-electron interaction in two-dimensional quantum dots. We show that second order correlation gives qualitative agreement with experiments on a level which was not found within the Hartree-Fock description. For weaker confinements, the second order correction is shown to be insufficient and higher order contributions must be taken into account. We demonstrate that all order Many-Body Perturbation Theory in the form of the Coupled Cluster Singles and Doubles method yields very reliable results for c

Abstract:

Semiconductor quantum dots (QDs) are fascinating systems for potential applications in quantum information processing and communication, since they can emit single photons and polarisation entangled photons pairs on demand. The asymmetry and inhomogeneity of real QDs has driven the development of a universal and fine post-growth tuning technique. In parallel, new growth methods are desired to create QDs with high emission efficiency and to control combinations of closely-spaced QDs, so-called "QD molecules" (QDMs). These systems are crucial for the realisation of a scalable information process

Abstract:

In this Ph.D thesis, electronic structure and transport properties of quantum dots are studied using advanced numerical techniques based on fundamental many-body theory. In fact, in such nanostructures, correlation and quantization effects dominate motion of electrons like in real atoms, hence an exact treatment is often necessary to understand and predict their electronic properties. Moreover, experimental realization of quantum dots in the presence of magnetic field gives rise to several new many-body physics that are inaccessible in real atoms, and they provide a crucial testing ground for

Abstract:

There are significant differences between experiment and theoretical calculations of the electronic structure of GaSb/GaAs self-assembled quantum dots. Using a multi-band effective mass approximation it is shown that the influence of size and geometry of quantum dots has little or no effect in determining the hydrostatic strain. Furthermore, the valenceband ground state energies of the quantum dots studied are surprisingly consistent. This apparent paradox attributed to the influence of biaxial strain in shaping the heavy-hole and light-hole potentials. Consequently, it is shown that a simple,

Quantum dots (QDs) are zero-dimensional nanostructures that confined carriers in three dimensions comparable to their de Broglie wavelengths. Therefore, carriers exhibit δ-shaped energy levels and densities of states. Due to their band structure, QD systems show significant advantages as active regions in laser cavities, both in term of lower threshold current densities and better thermal behaviour. The most studied system beingInAs/GaAs system but the antimonide-based (Sb-based) material system has been paid much attention due to their potential for optical devices in the 3-5 μm (0.25-0.40 eV

These structures are made from a simple one-step spin coating process of an electrostatically stabilized colloidal suspension.

Abstract:

The work discusses the development of molecular electronics based on the possibility of the usage of anorganic quantum dots and organic molecules as basis material. Of special interest are the properties of semiconductor quantum dots and their modification due to the coupling of quantum dots from different materials. Eventually these are proper candidates to avoid the fast recombination of excitons which is a problem in many organic photovoltaic materials, by local separation of charge carriers. Another materials class investigated are the so called charge transfer dimers. On the way to usable

Tesis (Lic. en Física)--Universidad Nacional de Córdoba. Facultad de Matemática, Astronomía y Física, 2011.<br>En este trabajo se presentan modelos de potencial finito que pueden ser utilizados para describir partículas atrapadas en puntos cuánticos en dos y tres dimensiones. El estudio de los modelos se realiza a partir de diferentes métodos, todos numéricos, y que se aplican luego de resolver el problema de autovalores y autovectores mediante un método aproximado: el Método de Ryleigh Ritz. En el caso de Dos Dimensiones se destacan los estados resonantes y los métodos utilizados para poder
