  1. Addressing Molecular Dynamics Time-scale Issues to Study Atomic-scale Friction

    12 Oct 2010 | | Contributor(s):: Ashlie Martini

    This presentation will include an introduction to several accelerated molecular dynamics methods. However, particular focus will be given to parallel replica (ParRep) dynamics in which atomistic simulations are run parallel in time to extend their total duration. The ParRep method is based on...

  2. Atomistic Simulations of Reliability

    06 Jul 2010 | | Contributor(s):: Dragica Vasileska

    Discrete impurity effects in terms of their statistical variations in number and position in the inversion and depletion region of a MOSFET, as the gate length is aggressively scaled, have recently been researched as a major cause of reliability degradation observed in intra-die and die-to-die...
