This back and forth motion of the electron beam causes it to emit electromagnetic radiation. (discovermagazine.com)
At that point, the ordinarily chaotic motion of the electrons gives way to a more orderly collective behavior governed by quantum mechanics. (scientificamerican.com)
In contrast, the coordinated, marching - band - like motion of electrons in vanadium dioxide is detrimental to heat transfer as there are fewer configurations available for the electrons to hop randomly between.» (sciencedaily.com)
