Das Verhalten der Elemente der III. Gruppe zueinander und zu den Elementen der IV. Gruppe

Abstract

Es werden die Zustandsdiagramme von: Aluminium/Indium, Gallium‐Thallium, Gallium/Silicium, Gallium/Germanium, Indium/Silicium, Indium/Germanium, Thallium/Germanium bestimmt. Die von Valentiner und Mitarbeitern bearbeiteten Zustandsdiagramme des Indiums mit Thallium, Zinn und Blei werden, zum Teil auf Grund neuer Versuche, erörtert. Es wird das Verhalten der Elemente der III. Gruppe zueinander wie zu den Elementen der IV. Gruppe besprochen. Es ergibt sich, daß die Elemente der III. Gruppe sowohl in der Tendenz zur Verbindungsbildung als auch in der Neigung zur Mischbarkeit ein Minimum aller Gruppen darstellen. Es wird eine einfache Heizkamera beschrieben .

Liquidus of Silicon Binary Systems

“…The liquidus in this system has been measured through thermal analysis, [79] weighting technique, [14,80] thermal analysis, and metallography. [81] The latter liquidus data seems not to be accurate and they are relatively lower than in other works.…”

Low-temperature growth of In-assisted silicon nanowires

“…In the vapor-liquid-solid (VLS) model for the growth of NWs [14], indeed, the liquidity of the nanoparticle inducing the growth is a requirement. The InSi intermetallic compound is however characterized by a very low amount of Si ( o0.1%) for To700 1C [15,16], a feature that leads to a quick supersaturation of the InSi nanoparticle that possibly induces the NW growth but, at the same time, should limit the NW growth rate. The cited works on In-induced NWs [9][10][11][12][13] often report results that rather indicate inefficient growth processes.…”

Calculation of Low-Temperature Phase Equilibria in the Indium-Lead System

“…Although phase equilibria of the In-Pb system have been studied by many investigators [ 1, 2, 4, 7, Downloaded by [University of Tennessee, Knoxville] at 17:36 04 June 2016 13,15,16,18,19,22,23,25,[31][32][33][34], the data reported in the literature are not in complete agreement. For instance, the disagreement in the solidus temperature is as large as 40 °C in the (Pb) solid solution region.…”

“…Limited phase boundary information has been obtained using X-ray analysis [1, 7,13,19,21,[31][32][33]. Heumann and Predel [7] predicted there is a miscibility gap in the (Pb) phase below ~30 oc at about 50 at.% Pb, based on their thermodynamic measurements.…”
