I will use the terms grain, granule, quantum dot, island, conductor, electrode, and node almost interchangeably, mainly to not being forced to use one word over and over. This should make this book more readable. However, each term carries a slightly different connotation. Island is probably the most general term and will be heavily used. Quantum dot emphasizes that discrete energy levels are present and important. For example, islands made from semiconductor are quantum dots since they exhibit almost always discrete energy levels. Grain and granule are more descriptive terms which convey information about the physical structure of the island. In contrast to a granule would be a two-dimensional electron gas quantum dot whose boundaries are defined by depletion gates, rather than material boundaries. Node, electrode, and conductor are synonyms. Node will be used on the circuit level. A node does not have to be an island. It can also be a conductor or an electrode. If a distinction between these terms is important, I will point that out separately where it applies. Thus for the remainder of this book regard these terms as loosely equivalent.
