  I had never considered this.

  Wonder if these materials are the kind of thing the "make your own integrated circuits" people would be able to use?

  > at frequencies up to 25 kilohertz

  How high could this technique go?

    > molybdenum disulfide for n-type transistors and tungsten diselenide for p-type transistors  
  

  Isn't this rather unusual?

  I wonder how this compares in speed and capabilities to photonic computers

  Molybdenum and tungsten both have melting point much higher than silicon, Maybe these circuits could be a good candidate for Venus rovers?

  Isn’t tungsten much much more expensive than silicon and harder to work with?

  A small step towards Sophons

  WTF is up with that illustration at the top of the article?
