Ab initio calculations on surface diffusion of Cu adatoms on Cu(001) are presented. The hopping mechanism with a calculated energy barrier of 0.69 eV is found to be favorable over the exchange mechanism with 0.97 eV. We find from the geometry relaxations t ...
An introduction to the Car-Parrinello (CP) method is given from the point of view of classical molecular dynamics. Here, a formulation is described that uses Vanderbilt's ultrasoft pseudopotentials, which yield generalized Kohn-Sham equations containing ov ...
Structural, electronic, and vibrational properties of NanMg clusters (n = 6-9, 18) have been detd. using the Car-Parrinello method. We find that in the energetically preferred structures the magnesium impurity is never located at the center of the cluster. ...
