(1999)The dipole polarizability of a series of clusters of the type LinHm has been calculated using density functional methods. The study of the trends in the mean polarizability and the anisotropy are explained in terms of the ...
-
(2007)Electronic structure and chemical reactivity of Cun clusters (n = 1-4) supported on a regular site (O5c) and on an oxygen vacancy (Fs and Fs+) of the MgO (1 0 0) surface were investigated using density functional theory. ...
