WitrynaThe electronic properties of isoelectronic impurity complexes in Si, such as Al+N and Mg+O, are studied by first-principles calculations. It is shown that cation and anion … Witryna18 sty 2024 · In such cases, complexation of the impurity with an additive can be used to sterically prevent impurity incorporation in the host lattice. A nanofiltration membrane can be used to preferentially reject the higher molecular weight impurity complex in solution, while allowing the lower molecular weight API to permeate through.
