A screening based study of impurity-dynamics in metals

  • S Sankar
  • K Chitra


The dynamics and energetics of a light impurity (hydrogen) embedded in metals (Al, Cu, and Ni) are studied using a phenomenological ‘local’ oscillator potential experienced by it as a result of its screened interaction with the host ions. Calculations of the migration energy of hydrogen in the above mentioned metals are reported.
