Re: Photons and Metals


"I said that the photodiode is detecting particles, not count, and particles it is, not waves! If laser light behaved exlusively as wave, as you are suggesting, you would not be able to use laser for cutting purposes because for cutting you need impulse, that means particles."

Photons have no mass (recall they travel at speed of light). Thus they can have no "impact" as you suggest. Lasers cut due to heat energy (photons have energy), not "impact." So your argument for particles falls away.

"Allen's analysis produced Nb, Ni, Cu, Zn, Al. None of these on its own would indicate quantum material. Or was there a further qualitative analysis I'm not aware of?"

If the lab had been told to try to use the TEM to inspect the core of the disc they might have seen the atoms of the crystal in the core of the dots, though that might not have been easy as there are not very many atoms. They were apparently only interested in the surface materials, as Allen initially thought the discs were simply aluminum foil. If Allen or folks at the lab knew anything about q-dots they might have suspected something unusual, as all the metals they identified are used in q-dots - some, not all q-dots. The metals they ID'd are used in various alloys - with each other, with other metals, as pure ultrathin films or as "dopants" (copper for example). I'm just saying it looks "suspicious." This is a circumstantial case, you just need to look at the evidence. BTW nobody noticed the curious bumpy surface of the silver dots; that is another clue.
