There were tons upon tons, and miles upon miles of the su-permetal, built one artificial atom at a time.

These discrete transitions are reminiscent of atomic spectra and have resulted in quantum dots also being called artificial atoms.

For example, one type uses a structure comprising nanowires containing quantum dots as the unit cells or artificial atoms of the structure.

In fact, quantum dots have often been referred to as "artificial atoms".

These structures act as artificial atoms because the material structure forces electrons to take on particular energy levels.

These artificial atoms usually are mesoscopic devices which exhibit an atom-like energy spectrum.

These are little packages of material that behave like artificial atoms.

Atomic electron transition is a change of an electron from one quantum state to another within an atom or artificial atom.

Quantum dots are in fact often referred to as artificial atoms.

Those electrons behave like artificial atoms which, like real atoms, can form covalent bonds, but these are extremely weak.
