Multiscale simulations applied to electrodeposited ultra-thin films

  • A funded postdoctoral position is available starting from June 2008 at the Institut de Chimie Moléculaire et des Matériaux d’Orsay (Paris, France) in the area of multiscale simulations of electrosorption kinetics.The proposal aims at understanding the role of the segregation in the processes of nucleation-growth of ultrathin alloy films AcB1-c electrodeposited on a homogeneous substrate. Such information on structures and kinetics is essential to modify -or even fit- the magnetic properties of electroplated nanomaterials. We will focus on applying a potential step on alloys with different thermodynamic properties (solid solution, tendency to order, to phase separate), for low and high deposit flux. A keypoint is to establish the consistency between atomic-scale numerical simulations (Kinetic Monte Carlo) and the macroscopic scale (Avrami laws) via the mesoscopic scale (cluster dynamics). Moreover, a systematic classification of island edge-co 6 novembre, 2008 eters is expected. Comparisons with STM in situ studies will bring detailed information, at the atomic scale, about the influence of substrate surface heterogeneities on the nucleation, growth, and crystalline structure of various films.
    • Keywords: Kinetic Monte Carlo simulations, Avrami law, nucleation-growth, cluster dynamics.
    • The position is full-time for 1.5 year
    • Applicants must hold PhD or equivalent in physics, chemistry or materials science. Expertise in materials modeling and simulation is expected.
