someone tries to explain cmos to the graphics dept

Some attempt to visually represent molybdenum disulfide and tungsten diselenide with the keys of a QWERTY keyboard.

If the frame is made of atoms what are the keys and display made out of? Quarks?

From the abstract[1]:

This enabled circuit operation below 3 V with an operating frequency of up to 25 kHz, which was constrained by parasitic capacitances

I would guess process improvements would help a lot towards lowering those parasitics. So I wouldn't take this initial attempt as a guide for ultimate speed.

Since this is 2D materials, a capacitor is a dielectric sandwiched by two conductors and capacitance scales linearly with area, I would assume just scaling things down would help immensely with parasitic capacitance. Changing materials or process could also change the dielectric constant which also affects the capacitance linearly.

Paper is sadly not open access, so I can't check if they mention this or have done some theoretical peak calculations or something. Would indeed be interesting to know.

Well—I, for one, welcome our new Trisolaran overlords!

Well with all the sabre-rattling by Kratsios on space time control, Sophons is not that far fetched.

Yes? But it’s been in research for a decade or two, based on a quick search.

It’s confusing to me because moly d is a very common lubricant, even for home uses.
