  1. Fundamentals of Current Flow

    30 Jan 2022 | | Contributor(s):: Supriyo Datta

    Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat...

  8. 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.

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Note: For an expanded version of these lectures see Datta's 2008 NCN@Purdue Summer School presentations on Nanoelectronics 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...
