Research on the jellium model and point defects in metal

On the basis of both the authors work on electronic structures and positron annihilation lifetimes for point defect and point-like defects in aluminium and the comparison with the related experimental data in details, the applicability of the jellium model as well as its correction are described. The validity and limitations of other density functional theory methods such as Puska's non-interaction atom model and PLAPW method are also discussed. It is shown that the jellium model is a useful tool to calculate the electronic structures of smaller voids (dia. <4 nm) in metals
