Comments by "" (@Gameboygenius) on "A Semiconductor Rare Earths Problem?" video.

  1. Basically, if the topic is an EM wave, the previous video was the B field and this video is the E field.

  2. He's done plenty of videos on battery technology. None of them use rare earth as far as I'm aware. For example, lithium ion batteries use elements like lithium (which is an alkali metal) and cobalt and manganese (which are transition metals).

  3. It really isn't at all at the moment.

  4. Manufacturing of this particular product... semiconductors. They're all over magnets and LEDs as noted.

  5. When he talked about the D shrinking I suspected he was making a diameter joke. When he said the follow-up comment I was certain he was making a diameter joke.

  6. Anything for a diameter joke!

  7. It's the same thing by a different name. Micron is not the name of the SI unit, but it's commonly used in industry. Probably because micrometer is a mouthful.

  8.  @punditgi  actually, nanometer feels like less of a mouthful to me. It's the two m's that do it for me. But all I'm saying is that it's not a big deal in this case. Just be glad it wasn't microinches. (Eww!) But maybe you're onto something with avoiding nanometers. The semiconductor industry node names basically have nothing to do with feature sizes at this point. So to embrace that, they stopped calling it for example the 5 nm node and now call it the N5 node.

  9. He mentioned the cerium slurry briefly, but not scandium for piezoelectric films. Interesting!
