Analogies Between Ballistic Electrons and Electromagnetic Waves

  • Chapter
Quantum-Classical Analogies

Part of the book series: The Frontiers Collection ((FRONTCOLL))

Abstract

One of the best known and most widely exploited analogies between classical physics and quantum mechanics is that between the time-independent Schrödinger equation and the Helmholtz equation, i.e., the time-independent form of Maxwell’s equations. Electrons in bulk semiconductors or heterostructures do not behave like waves, and thus cannot be described by the Schrödinger equation unless:

  1. (i)

    the interactions between electrons and the periodic crystal lattice, and between different electrons, do not appear explicitly in the electron equation of motion

  2. (ii)

    the collisions between different electrons as well as the interference effects between the wavefunctions of different electrons can be neglected.
