MIT physicists have trapped electrons in a pure crystal, marking the first achievement of an electronic flat band in a three-dimensional material. The results provide a new way for scientists to explore rare electronic states in 3D materials.

      Very small rocks … with some kind of tiny furnace, bitty crucible, and naturally a wee glass blower.

    “Trapping electrons in a crystal” is such a nonsensical way of conveying the idea of a flat band. Most isolated crystals trap all the electrons they have inside of them, or else the world will be full of free roaming electrons!
