A team of researchers at Princeton University's Materials Research Science and Engineering Center has observed electrons moving through a crystal of bismuth metal behaving like light.
This discovery, supported by the National Science Foundation (NSF) and detailed in today's edition of the journal Science, could lead to new kinds of electronic devices.
Electrons, or the particles of electricity, fly through space like tiny baseballs. Alternatively, when an electron speeds between a crystal's periodic arrangement of atoms it behaves very differently. The fundamental equations that describe its motion in the crystal are very different from those of a free-flying baseball. For example, in bismuth, the fundamental equations of electron motion resemble those that describe the behavior of light. Although the electrons whirl about the crystal slower than at the speed of light, the electron
