Research ArticleOpen accessEvery word in the titleThe 'Umbrella' Function Describing the Density of External Electrons Injected in NaCl CrystalSiti Wahyuni, Akrom Khasani, Wipsar Sunu Brams Dwandaru, Muhammad Farchani RosyidElectrons injected in NaCl crystal are studied using Thomas-Fermi-Dirac-von Weizsacker (TFDW) model. The external potential that contributes to the TFDW energy functional is not only due to the nuclei but also to the internal electrons. In order to obtain the potential term due to the internal electrons, the density of the internal electrons in the crystal is derived from the … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 1 Dec 2016 · 8,296 accessesView PDF Cite
