Quantum size effects of Pb overlayers at high coverages.
(Elsevier, 2007-07-18)
We have studied Pb thin films as a function of the thickness up to 60 monolayers (MLs) using ab initio first principles and model calculations. Magic heights corresponding to a modulated oscillatory pattern of the energy ...
Restored quantum size effects of Pb overlayers at high coverages
(APS, 2007-04-10)
Abnormally large stability of Pb nanostructures grown on metallic or semiconductor substrates has been observed even for heights of about 30 monolayers. Using both density-functional theory calculations and analytical ...
Positron lifetime calculation of the elements of the periodic table
(IOP, 2007-04-10)
Theoretical positron lifetime values have been calculated systematically for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic ...
