With the help of selective etching, transmission electron microscopy complex researches of non‐doped dislocation‐free single crystals of float‐zone silicon by a diameter of 30 mm were conducted. The crystals were obtained with various growth rates and were subjected to various kinds of technological effects. Is established that the process of microdefects formation in silicon proceeds simultaneously on two independent mechanisms:vacancy and interstitial. The physical model of formation of microdefects in dislocation‐free monocrystals of FZ silicon is offered.

Reduced Lattice Specific Heat Due to Light Vanadium Impurities in Gold

The reduction in lattice specific heat due to light vanadium impurity atoms in gold crystals observed earlier by Star et al. is explainedon the basis of a low concentration Green's function theory. A localized perturbation model which includes mass change a t the impurity site as well as changes in the nearest neighbour force constants has been employed performing the calculations. Reasonable agreement with the experimental data in two (Au-0.33 at% V and Au-1 at% V) of the three dilute alloys is obtained. The mass defect contribution is only 20% of the changed specific heat and the remaining contribution is due to force constant changes. The main contributions to the changed specific heat is caused by even parity A1 g-, E2 g,-F2 g-, and F1 g-symmetry modes, a feature which is not usually observed in other defect-induced physical properties.Die durch leichte Vanadium-Stijrstellenatome in Goldkristallen schon friiher von Star et al. beobachtete Verringerung der spezifischen Warme des Gitters wird auf der Grundlage der Methode Greenacher Funktionen fur niedrige Konzentrationen erkllirt. Ein Model1 lokalisierter Storung, das sowohl die MassenLnderung am Storstellenplatz als auch Bnderungen der Kraftkonstanten der niichsten Nachbarn einschliellt, wird fur die Berechnungen verwendet. Befriedigende ubereinstimmung mit den experimentellen Werten wird in zwei (Au-0,33 At% V und Au-1 Atyo V) der drei verdiinnten Legierungen erhalten.Der Beitrag ist nur 20% der gelinderten spezifischen Warme und der restliche-Beitrag wird durch Anderungen der Kraftkonstante verursacht. Der Hauptbeitrag zur Anderung der spezifischen Wlirme wird durch Alg-, Ezg-, Fzg und F1 g-Moden gerader Paritat verursacht, ein Verhalten, das gewohnlich nicht bei anderen durch Storstellen induzierten physikalischen Eigenschaften beobachtet wird.
