Progress in semiconductor technology has enabled the fabrication of structures so small that
they can contain just one mobile electron. By varying controllably the number of electrons in …

The properties of quasi-two-dimensional semiconductor quantum dots are reviewed.
Experimental techniques for measuring the electronic shell structure and the effect of …

Many important phenomena in quantum devices are dynamic, meaning that they cannot be
studied using time-averaged measurements alone. Experiments that measure such transient …

We examine the possible implementation of logic devices using coupled quantum dot cells.
Each quantum cell contains two electrons which interact Coulombically with neighboring …

We describe a paradigm for computing with interacting quantum dots, quantum-dot cellular
automata (QCA). We show how arrays of quantum-dot cells could be used to perform useful …

We review some electron transport experiments on few-electron, vertical quantum dot
devices. The measurement of current versus source-drain voltage and gate voltage is used …

This review seeks to extend the scope of both the experimental and theoreticalwork carried
out since I completed my 1993 review on the electronic, optical, andto a lesser extent, the …

The control of electrons at the level of the elementary charge e was demonstrated
experimentally already in the 1980s. Ever since, the production of an electrical current ef, or …

We observe second-harmonic generation from metamaterials composed of split-ring
resonators excited at 1.5-micrometer wavelength. Much larger signals are detected when …

We study atomiclike properties of artificial atoms by measuring Coulomb oscillations in
vertical quantum dots containing a tunable number of electrons starting from zero. At zero …
