Regular semiconductor material island array for a Coulomb blocking type quantum device, e.g. a memory or a logic circuit

摘要

An array of semiconductor material islands (124) is formed on uniformly distributed nucleation seeds (122, 122a) deposited on an insulating material (112) using a distribution layer (116) of material having a regular molecular structure. Independent claims are also included for the following: (i) production of a quantum structure of Coulomb blocking type having an array of semiconductor islands formed by the above process; and (ii) a Coulomb blocking type electronic device having electron sources separated by a collection of nano-size semiconductor islands regularly spaced on an insulating substrate.
