A quantum dot molecule (QDM) is composed of two or more closely spaced quantum dots or “artificial atoms.” In recent years, QDMs have received much attention as an emerging new artificial quantum system. The interesting and unique coupling and energy transfer processes between the “artificial atoms” could substantially extend the range of possible applications of quantum nanostructures. This book reviews recent advances in the exciting and rapidly growing field of QDMs via contributions from some of the most prominent researchers in this scientific community. The book explores many interesting topics such as the epitaxial growth of QDMs, spectroscopic characterization, and QDM transistors, and bridges between the fundamental physics of novel materials and device applications for future information technology. Both theoretical and experimental approaches are considered. Quantum Dot Molecules can be recommended for electrical engineering and materials science department courses on the science and design of advanced and future electronic and optoelectronic devices.

Quantum dots (QDs) are luminescent semiconductor nanocrystals with unique chemical and physical properties due to their size and highly compact structure. QDs were first proposed for use in luminescent concentrators to replace organic dye molecules. In this book, the interest is in taking advantage of the emission properties of QDS, which can be tuned by their size, resulting from quantum confinement. In addition, the book discusses the potential of QDs as contrast and therapeutic agents in the field of medicine.

Since the early 1990s, quantum dots have become an integral part of research in solid state physics for their fundamental properties that mimic the behavior of atoms and molecules on a larger scale. They also have a broad range of applications in engineering and medicines for their ability to tune their electronic properties to achieve specific functions. This book is a compilation of articles that span 20 years of research on comprehensive physical models developed by their authors to understand the detailed properties of these quantum objects and to tailor them for specific applications. Far from being exhaustive, this book focuses on topics of interest for solid state physicists, materials scientists, engineers, and general readers, such as quantum dots and nanocrystals for single-electron charging with applications in memory devices, quantum dots for electron-spin manipulation with applications in quantum information processing, and finally self-assembled quantum dots for applications in nanophotonics.

Quantum dots (QDs) that are separated from each other by a small potential barrier can be connected by quantum tunneling. The electrons that tunnel between these quantum dots act in a similar manner to electrons in naturally occurring molecules, which is why coupled QDs are called QD molecules. I use the finite dfferences method to numerically calculate the energy levels and wave functions of electrons trapped in quantum dots and quantum dot molecules in the conduction band. The objective is to develop and test an accurate numerical method for the conduction band of various quantum dot systems. First, numerical energy levels and wave functions are compared to their analytical counterparts for two simple potentials.

Ongoing developments in nanofabrication technology and the availability of novel materials have led to the emergence and evolution of new topics for mesoscopic research, including scanning-tunnelling microscopic studies of few-atom metallic clusters, discrete energy level spectroscopy, the prediction of Kondo-type physics in the transport properties of quantum dots, time dependent effects, and the properties of interacting systems, e.g. of Luttinger liquids. The overall understanding of each of these areas is still incomplete; nevertheless, with the foundations laid by studies in the more traditional systems there is no doubt that these new areas will advance mesoscopic electron transport to a new phenomenological level, both experimentally and theoretically. Mesoscopic Electron Transport highlights selected areas in the field, provides a comprehensive review of such systems, and also serves as an introduction to the new and developing areas of mesoscopic electron transport.

Self-assembled lateral InAs quantum dot molecules (QDMs) are grown by solid-source molecular beam epitaxy (MBE) technique using the thin-capping-and-regrowth MBE process. Thin-capping of GaAs on as-grown InAs quantum dots (QDs) at low temperatures leads to nanohole templates. The shape, size and depth of nanoholes are controlled by capping thickness. Subsequent regrowth with 0.6 ML of InAs on the templates result in nano-propeller QDs with different blades' dimensions. We found that the length of the propeller blades is controlled by either the capping temperature or the thickness of capping layer. When the amount of InAs regrowth layer increases from 0.6 to 1.2 and 1.5 ML, QDMs with different shapes are created. The center dots are formed by filling up nanoholes at the beginning phase until the strain relaxation at center becomes minimized. Later on, the rest of InAs regrowth material starts to form satellite dots along the blade of nano-propeller where remaining strain fields are still distributed at the perimeter of nano-propeller blades. The dot uniformity and their dot size of all QDM samples are examined by photoluminescence (PL) measurements at 77 K. Furthermore, the excitation power dependence of PL spectra of all samples is also conducted. The PL results from some case of different QDMs also exhibit the shift of the PL peaks toward higher energies. We believe that the coupling between center dot and satellite dots lead to the extending in their band structures.
