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:
“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)
“For life is but a dream whose shapes return,
Some frequently, some seldom, some by night
And some by day,”
—James Thomson (1834–1882)
“Her bones
under the flesh are white
as sand which along a beach
covers but keeps the print
of the crescent shapes beneath.”
—Hilda Doolittle (1886–1961)
