8. Modeling Resonance Tunneling using Wave Packets

Some AVI movies.

  • Single Barrier Tunneling - Wave packet hitting a single barrier.
  • First Resonant Energy - Wave packet incident with energy equal to ground state of the square well between the double barriers.
  • Second Resonant Energy - Wave packet incident with energy equal to the first excited state of the square well between the double barriers. Note the node in the reflected wave.
  • No Bias Voltage - RTD in the off mode.
  • Resonant Bias Voltage - RTD in the on mode.
