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 impurity atoms prefer to locate at the nearest-neighboring sites and produce an electron-unoccupied state in the band gap of Si. Witryna1 sty 2000 · Impurity isolation and subsequent off-line mass spectrometry have often been used to confirm the identity of drug impurities and degradates by comparison, if … Witrynamore complex than straightforward chemical reactions.
