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:
“Incarnate devil in a talking snake,
The central plains of Asia in his garden,
In shaping-time the circle stung awake,
In shapes of sin forked out the bearded apple....”
—Dylan Thomas (1914–1953)
“Runs falls rises stumbles on from darkness into darkness
and the darkness thicketed with shapes of terror
and the hunters pursuing and the hounds pursuing
and the night cold and the night long and the river
to cross and the jack-muh-lanterns beckoning beckoning
and blackness ahead”
—Robert Earl Hayden (1913–1980)
“Nothing can happen nowhere. The locale of the happening always colours the happening, and often, to a degree, shapes it.”
—Elizabeth Bowen (1899–1973)
