  3. For a length within the ballistic regime, why the current value changing with the length ?

    Open | Responses: 1

    Hi !

    Ok, I considered the relaxation time to find the relaxation length ( L = tau * Vf = 36.8 um  ; taking Vf = 8.10^5m/s )

    And so I chose 2 values for the...

    Note: For an expanded version of these lectures see Datta's 2008 NCN@Purdue Summer School presentations onNanoelectronics and the Meaning of Resistance.How does the resistance of a conductor change as we shrink its length all the way down to a few atoms? This is a question that has intrigued...

  9. Device Physics and Simulation of Silicon Nanowire Transistors

    27 Jun 2013 | | Contributor(s):: Jing Wang

    As the conventional silicon metal-oxide-semiconductor field-effect transistor (MOSFET) approaches its scaling limits, many novel device structures are being extensively explored. Among them, the silicon nanowire transistor (SNWT) has attracted broad attention from both the semiconductor industry...

  10. Dissipative Quantum Transport in Semiconductor Nanostructures

    23 Dec 2011 | | Contributor(s):: Peter Greck

    In this work, we investigate dissipative quantum transport properties of an open system. After presenting the background of ballistic quantum transport calculations, a simple scattering mechanism, called Büttiker Probes, is introduced. Then, we assess the properties of the Büttiker Probe model...
