Phase diagram and thermodynamic properties of Ag−Cu alloys
Interactive laws of the components described by Gibbs energy functions of CC theory are different from each other, but each G-function can be used to draw the phase diagram of Ag−Cu system with almost the same accuracy. The partial molar properties of the components obtained from all these G-functions are identical. This shows the defects of thermodynamics of alloys. The thermodynamic properties of Ag−Cu alloys and their components have been calculated by the correct G-function which is chosen through a relative study of the energy, volume, atomic arrangement and electronic structure.
We demonstrate GaSb overgrowth over tungsten patterns and that selective area epitaxy is achievable in the W/GaSb system. By controlling the facet growth at low temperatures, it is possible to embed a metal grating in a thin layer.
