The Au-In-Ga ternary phase diagram is of importance for understanding the involved thermodynamic processes during the growth of Au-seeded III-V heterostructure nanowires containing In and Ga (e.g. Au-seeded InAs/GaAs nanowires). In this work the Au-In-Ga system has been thermodynamically modeled using the CALPHAD technique based on a recent experimental investigation of the phase equilibria in the system. As a result, a set of selfconsistent interaction parameters have been optimized that can reproduce most of the experimental results.

Growth of intermetallic compounds in the Au–In system: Experimental study and 1-D modelling

The gold-indium system is of primary interest for bonding processes such as solid-liquid interdiffusion bonding. In order to optimize the manufacturing parameters, it is essential to know which intermetallic compounds (IMCs) are formed when solid Au and liquid In are brought into close contact with each other, and what are their growth kinetics. For this purpose, we fabricated diffusion couples above and below the melting point of In (for T ¼ 250 and 150°C respectively). Three IMCs, identified as AuIn 2 , AuIn and Au 7 In 3 , are always observed in the reaction zone, even after short times. AuIn 2 is the thickest and fastest growing layer and AuIn is only present as a thin layer. Whereas AuIn 2 and AuIn exhibit an equiaxed structure, Au 7 In 3 is found to grow as columnar grains. The diffusion coefficients in each phase were determined by means of a 1-D finite difference modelling of In diffusion. The values are consistent and can be used to predict the growth rate as a function of temperature and time, i.e. to simulate a whole bonding process with finite thicknesses.

“…4(c)), the shape of the particle closely resembles that of the gold particle directly after imprinting (Fig. 4(e)), indicating that the particle is still solid, likely in the α-phase [26]. If any stem is grown, it is too small to be observed by SEM imaging and most probably grown in the vapor-solid-solid growth mode.…”

“…Let us first discuss how the particle can reach a liquid state. The Au-In binary system has a eutectic point at an In composition of 35%-40% and a temperature of about 450 °C [26]. For the gold particle to reach a composition at which it can melt at the annealing temperatures studied here, it needs to approach the eutectic composition by going through solid state phase transformations, studied by several authors [27][28][29][30].…”
