A quantum dot gets its name because it's a tinyspeck of matter so small that it's effectivelyconcentrated into a single point (in other words, it's zero-dimensional). As a result, the particlesinside it that carry electricity (electrons and holes, which are places that are missing electrons) are trapped …
