> can we not drill 0.2nm holes in silicon for instance? I think that this is interesting question, and should not be waved away with "just drill some 0.2nm holes, use a real small drill bit" 0.2nm is tiny, given that it's on a scale that impacts how H2O molecules behave. It's also smaller than our ability to make the circuits in computer chips, which are currently > 1 mn (1). Use a laser? Light with a comparable wavelength is x-rays. As used in the chip manufacturing (2) This is about size of the spacing between individual atoms (3) So it seems like a material with 0.2nm holes "drilled" into it would be a major engineering feat at least. 1) https://research.ibm.com/blog/1nm-chips-vtfet-ruthenium https://research.ibm.com/blog/1nm-chips-vtfet-ruthenium 2) https://en.wikipedia.org/wiki/X-ray_lithography https://en.wikipedia.org/wiki/X-ray_lithography 3) https://en.wikipedia.org/wiki/Atomic_spacing https://en.wikipedia.org/wiki/Atomic_spacing
