Anyone know what the hell they are talking about? I'm flummoxed.

Originally posted by apathistElectron holes occur in a crystal structure like doped silicon, the basis for computer chips. The hole in silicon doped with a conductor like Boron creates a charge different from the silicon atoms around the crystal. When doped, the boron takes the place of a silicon atom in the crystal and becomes a kind of way station for electrons because pure silicon is an insulator. But electrons can jump from one boron atom to another or it's opposite charge Phosphorus. The big three dopants in silicon are Arsenic, phosphorus and boron. I was a field service engineer for Varian ion implanters for 20 years, and that was the main job the ion implanter did, it slams one of those big three ions into a silicon wafer which buries itself under the surface under 1 micron deep. But that is only the first part of the story.
"The scientists explained that, by definition, the electrons in a chiral channel can only move in one direction. To induce supercurrent, an information transfer in the direction opposite to this direction is required."
Reminds me of electron holes.
