abstract = {Nano-scale alloy systems with at least one dimension below
100 nm have different phase stabilities than those observed
in the macro-scale systems due to a large surface to volume
ratio. We have used the semi-empirical thermodynamic
modelling, i.e. the CALPHAD method, to predict the phase
equilibria of the In–Sb nano-scale systems as a function
of size and shape. To calculate the size- and
shape-dependent phase diagram of the In–Sb system, we have
added size-dependent surface energy terms to the Gibbs
energy expressions in the In–Sb thermodynamic database. We
estimated the surface energies of the solution phases and of
the InSb intermetallic phase using the Butler equation and
DFT calculations, respectively. A melting point and eutectic
point depression were observed for both nanoparticle and
nanowire systems. The eutectic composition on the In-rich
and Sb-rich sides of the phase diagram shifted towards
higher solubility. We believe that the phase diagram of
In–Sb nano-alloys is useful for an increased understanding
of the growth parameters and mechanisms of InSb
nanostructures.},
