  1. Quantum Ballistic Transport in Semiconductor Heterostructures

    27 Aug 2007 | | Contributor(s):: Michael McLennan

    The development of epitaxial growth techniques has sparked a growing interest in an entirely quantum mechanical description of carrier transport. Fabrication methods, such as molecular beam epitaxy (MBE), allow for growth of ultra-thin layers of differing material compositions. Structures can be...

  2. Towards a Terahertz Solid State Bloch Oscillator

    29 Jan 2004 |

    The concepts of Bloch oscillation and Zener breakdown are fundamental to electron motion in periodic potentials and were described in the earliest theoretical developments of electron transport in solids. But only in the past 10 years have experiments clearly demonstrated various aspects of...
