Impurity positioning
Witryna15 lut 2012 · It turns out that the EBS is extremely sensitive in determining the critical disorder level for which delocalized states start to appear in the intermediate band. In addition, the EBS allows us to identify the role played by atomic relaxation in the positioning of the impurity more » Authors: Popescu, Voicu; Zunger, Alex … Witryna1 lut 2024 · The effect of the impurity position on the arrangement patterns of the one-dimensional chains, namely nine site (odd) chain on left, and eight site (even) chain on right. The hollow circles represent the ordinary sites while the black circle stands for the impurity atom. The left odd chain exhibits two patterns depending on the position of …

We consider magic-size icosahedral clusters made of 147 and 309 atoms, corresponding to sizes in the range 1.8–2.2 nm.
Witryna1 wrz 2005 · Fig. 3 presents the dependencies of electron binding energy on the QW width at impurity intermediate position (z i = L / 4).It is obvious that in the same way, as at central positioning, the larger values of γ parameter correspond to the larger values of energies. But in this case the binding energy is less than at z i = 0.It is related to the …
