Shapes
Nanostructures of virtually any 3-dimensional shape can be deposited using computer-controlled scanning of electron beam. Only the starting point has to be attached to the substrate, the rest of the structure can be free standing. The achieved shapes and devices are remarkable:
- World smallest magnet
- Fractal nanotrees
- Nanoloops (potential nanoSQUID device)
- Superconducting nanowires

Famous quotes containing the word shapes:
“The freedom of indifference, the indifference of freedom, the will dust in the dust of its object, the act a handful of sand let fall—these were some of the shapes he had sighted, sunset landfall after many days.”
—Samuel Beckett (1906–1989)
“The gods themselves,
Humbling their deities to love, have taken
The shapes of beasts upon them. Jupiter
Became a bull, and bellowed; the green Neptune
A ram, and bleated; and the fire-robed god,
Golden Apollo, a poor humble swain.”
—William Shakespeare (1564–1616)
“All know that all the dead in the world about that place are stuck
And that should mother seek her son she’d have but little luck
Because the fires of Purgatory have ate their shapes away;
I swear to God I questioned them and all they had to say
Was fol de rol de rolly O.”
—William Butler Yeats (1865–1939)
