Book Description
Semiconductor nanostructures are ideal systems to tailor the physical properties via quantum effects, utilizing special growth techniques, self-assembling, wet chemical processes or lithographic tools in combination with tuneable external electric and magnetic fields. Such systems are called "Quantum Materials".The electronic, photonic, and phononic properties of these systems are governed by size quantization and discrete energy levels. The charging is controlled by the Coulomb blockade. The spin can be manipulated by the geometrical structure, external gates and by integrating hybrid ferromagnetic emitters.This book reviews sophisticated preparation methods for quantum materials based on III-V and II-VI semiconductors and a wide variety of experimental techniques for the investigation of these interesting systems. It highlights selected experiments and theoretical concepts and gives such a state-of-the-art overview about the wide field of physics and chemistry that can be studied in these systems.

Book Description
Reducing the size of a coherently grown semiconductor cluster in all three directions of space to a value below the de Broglie wavelength of a charge carrier leads to complete quantization of the energy levels, density of states, etc. Such “quantum dots” are more similar to giant atoms in a dielectric cage than to classical solids or semiconductors showing a dispersion of energy as a function of wavevector. Their electronic and optical properties depend strongly on their size and shape, i.e. on their geometry. By designing the geometry by controlling the growth of QDs, absolutely novel possibilities for material design leading to novel devices are opened. This multiauthor book written by world-wide recognized leaders of their particular fields and edited by the recipient of the Max-Born Award and Medal 2006 Professor Dieter Bimberg reports on the state of the art of the growing of quantum dots, the theory of self-organised growth, the theory of electronic and excitonic states, optical properties and transport in a variety of materials. It covers the subject from the early work beginning of the 1990s up to 2006. The topics addressed in the book are the focus of research in all leading semiconductor and optoelectronic device laboratories of the world.

Book Description
Advancements in our control and understanding of quantum systems promise dramatic change in technology, potentially affecting fields of computation, sensing, and even power transmission. These grand possibilities are driven by new phenomena that emerge from strong quantum mechanical interactions between electrons in a material. One limitation to realizing these breakthroughs is that much of the exotic behavior present in quantum materials occur in conditions not suitable for practical applications, for example, very low temperatures or high pressures. Understanding why these novel properties emerge may provide insight into overcoming such limitations. One avenue to better our understanding is quantum simulation, in which a highly controllable experimental system is used to directly implement the physics of these quantum materials. In this thesis we build on a new approach to quantum simulation, using hybrid metal-semiconductor island nanostructures. The hybrid structure combines the advantages of both metal and semiconductor nanostructures -- sites that behave uniformly and couplings that are highly tunable. Each island can act as a single lattice site, with electrons that may interact with other lattice sites or a surrounding bath of conduction electrons. However, before scaling to lattices where the physics of bulk materials can be replicated, a crucial step is understanding how two such islands interact with each other. To probe the inter-island interaction, we build and study a two-island device, and find that the inter-island interaction arises from a Kondo-like screening of charge states acting as a pseudospin. When each island is also coupled to a single lead via a Kondo interaction, the resulting competition leads to a quantum critical point. We find that this is well described by a double charge Kondo model, and our transport measurements well match numerical renormalization group calculations. In particular, we study how critical behavior is destroyed following a particular universal scaling form when detuning from charge degeneracy, where criticality occurs.
