Recent years have witnessed the discovery of many striking new aspects of the optical response and electronic transport phenomena. This book surveys this progress in the physics, optical spectroscopy and application-oriented research of semiconductor quantum dots. It focuses especially on excitons, multi-excitons, their dynamical relaxation behaviour and their interactions with the surroundings of a semiconductor quantum dot. Recent developments in fabrication techniques are reviewed and potential applications discussed.

Book excerpt: Confined quantum many-body systems of a given particle number exhibit a variety of intrinsic shape characteristics as a function of increasing external field and internal thermal excitation. The shell model is an important tool for the theoretical description of these various structures and transitions in nuclei. Another system in which correlations beyond the mean field may play an important role is semiconductor quantum dots. In this Proceedings, the author compares nuclei and quantum dots and their various deformation properties. The author reports on shell-model calculations in nuclei and some recent mean-field calculations of the thermal properties of quantum dots.

This book was released on 2009 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a multidisciplinary thesis research in semiconductor quantum dot (QD) field and includes two parts. On one hand, the strain-induced local electronic band edges in single QD are studied using a kp description of the electronic eigenstates coupled with the induced lattice strain as calculated using the continuum mechanics (CM) description. In the CM method, the misfit-lattice induced strain can be reduced to an analytical expression that is straightforward to evaluate numerically. Different from most previous analyses for QDs in infinite spaces, QDs are assumed to have different shapes and lattice orientations located in half-space substrates which more realistically describe experimental situations in most instances. The band edges within the cubic and pyramidal InAs QDs embedded in GaAs substrates are predicted with the six-band kp basis approach. Comparison between the strain-induced local band edge based on the approximate method and exact method shows that the approximate method could result in substantial error near the interface region of the QD. The strain-induced band edges along the bottom center line of the QD can differ by a factor of two between the two approaches. Furthermore, the effect of the free surface on the strain-induced band edges is studied by varying the depth of the buried QD. When the QD is moved away from the surface, the band edges converge in a consistent way to the infinite space solution. Comparison with available experimental results validates our exact model within the half-space substrate and shows the importance of treating the surface in a theoretically rigorous way. On the other hand, once we have achieved our study for a particular QD, the next logical and natural step is to fabricate consistent QDs with uniform size and distribution. The multilayer structure (superlattice) which is governed mainly by the distribution of the long-range elastic strain energy, is an effective route for improving the uniformity of QDs. Based on the rigorous strain energy calculation, a scaling behavior on the dimensionless lateral (horizontal) spacer versus vertical spacer (xdist/b versus hdist/h) for multilayer quantum dots (QDs) distribution is proposed and four typical correlation regimes - aligned correlation, transition zone, antialigned correlation and non-correlation, are predicted via varying the dimensionless parameters. It is shown that the prediction matches well with available experimental data for semiconductors with low elastic anisotropy (A

This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of strongly correlated fermions and bosons in a disordered envi ronment and confined geometries is at the focus of intense experimental and theoretical research efforts. Advances in material technology and in low temper ature techniques during the last few years led to the discoveries of new physical of atomic gases and a possible metal phenomena including Bose condensation insulator transition in two-dimensional high mobility electron structures. Situ ations were the electronic system is so dominated by interactions that the old concepts of a Fermi liquid do not necessarily make a good starting point are now routinely achieved. This is particularly true in the theory of low dimensional systems such as carbon nanotubes, or in two dimensional electron gases in high mobility devices where the electrons can form a variety of new structures. In many of these sys tems disorder is an unavoidable complication and lead to a host of rich physical phenomena. This has pushed the forefront of fundamental research in condensed matter towards the edge where the interplay between many-body correlations and quantum interference enhanced by disorder has become the key to the understand ing of novel phenomena.

In Section 2, a few topics of magnetic quantum dots and their applications are presented. The section starts with a theoretical model to describe the magnetization dynamics in magnetic quantum dot array and the description of dilute magnetic semiconducting quantum dots and their applications.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts
