Is a tip of a human hair smaller than a transistor?

1 Answer

Answer :

That depends on the transistor, but in modern integratedcircuits, a single transistor is somewhere around a hundred atomsthick; the largest atom is about 0.5 nm in diameter, so a hundredatoms would be about 50 nm. On the other hand, a typical humanhair, according to Wikipedia, has a width "from 0.017 to 0.18millimeters"; that would be 17-180 µm, which is much larger.
