3. Lecture 3: Resistance-Ballistic to Diffusive

   28 Jul 2011 | | Contributor(s):: Mark Lundstrom

   The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.

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

   Q&A|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 length...

    out of 5 stars 

    10 Sep 2008 | | Contributor(s):: Mark Lundstrom

    The IV characteristic of the ballistic MOSFET is formally derived. When Boltzmann statistics are assumed, the model developed here reduces to the one presented in Lecture 2. There is no new physics in this lecture - just a proper mathematical derivation of the approach that was developed...
