while we're on thin and japan companies, youtube taught me about Disco, the wafer slicing disc company. Such a "trivial" problem in definition yet very impressive when you think about it.

> while we're on thin and japan companies, youtube taught me about Disco, the wafer slicing disc company. That sounds interesting! Could you point to any good video?

I forgot which video talked about that, but there are a lot of video about it.

here's a tiny history https://www.youtube.com/watch?v=5f5Gfeekl5Q

search for wafer dicing disco, lots of machinery

The number for gold leaf cannot be right. The unit cell spacing for gold is around 0.4 nm. At 0.1nm you will have monolayer gold. By the way, the first monolayer metals were synthesized just last year, and published this March in Nature Materials.

You're right, it's 100 nanometers. I first wrote "100 nanometers", then decided to convert to microns to make it easier to compare to the other thicknesses, and then forgot to change the unit name from "nanometers" to "microns". Also "a hundred times thinner" should read "a thousand times thinner". Thank you for the correction! I thought iron monolayers had been made in 2014?

They were just around 10-20 atoms that were inside graphene holes. They were technically the first, but I have big doubts about their scalability. The new work I was mentioning comes from Josh Robinson's lab at Penn State - the same guys that synthesized monolayer gallium nitride 3 years back.

I see! Thank you!
