Witryna27 maj 2011 · First-principles studies have provided an insight into the energetics and atomic and electronic structures of native point defects and impurities and defect-induced properties of ZnO. Native defects that are relevant to the n-type conductivity and the non-stoichiometry toward the O-deficient side in reduced ZnO have been debated. … Witryna11 kwi 2024 · We investigate thermodynamic and electronic properties of group IV (C, Si, Ge, Sn) and group VI (O, S, Se, Te) impurities as well as P and H in aluminum antimonide (AlSb) using first-principles calculations. To this end, we compute the formation energies of a broad range of possible defect configurations including …

WitrynaIn Section 3.1, the various mechanisms for diffusion of impurities in silicon are introduced and discussed. Most important for impurities residing predominantly on substitutional sites are mechanisms in which they form mobile pairs with intrinsic point defects. The energetics of such pairs is discussed in detail in Section 3.2. Witryna2 dni temu · The resistivity of metal is mainly caused by a phonon, dislocation, point defects (soluble atoms, impurities, vacancies, etc.), and the scattering effect of the interface on electrons. The resistance of high-purity Cu is mainly determined by dislocation defects and grain boundaries. Cu strips have higher resistivity because of …
