Abstract
We have realized arrays of quantum dots on InSb and observe intraband transitions between their discrete (zero-dimensional) electronic states with far-infrared magnetospectroscopy. In our devices, the number of electrons can be adjusted by a gate voltage and less than 5 electrons per dot are detectable.Keywords
