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:
“Taught from their infancy that beauty is woman’s sceptre, the mind shapes itself to the body, and, roaming round its gilt cage, only seeks to adorn its prison. Men have various employments and pursuits which engage their attention, and give a character to the opening mind; but women, confined to one, and having their thoughts constantly directed to the most insignificant part of themselves, seldom extend their views beyond the triumph of the hour.”
—Mary Wollstonecraft (1759–1797)
“‘Tis not alone my inky cloak, good mother,
Nor customary suits of solemn black,
...
Together with all forms, moods, shapes of grief,
That can denote me truly.”
—William Shakespeare (1564–1616)
“Men expect too much, do too little,
Put the contraption before the accomplishment,
Lack skill of the interior mind
To fashion dignity with shapes of air.
Luxury, yes but not elegance!”
—Allen Tate (1899–1979)
