a, The Bi-Ga binary phase diagram. The Bi-Ga mixing ratios that have been investigated in this study are marked with red boxes with the labels indicating different sample groups. b, Surface patterns formed on a hypoeutectic sample (Bi0.001Ga0.999). c, Surface patterns formed on a eutectic sample (Bi0.0022Ga0.9978). d-g, Surface patterns formed on hypereutectic samples: d,e, Bi0.085Ga0.915; f, Bi0.50Ga0.50, and g, Bi0.99Ga0.01. In the Bi0.085Ga0.915 sample, both few-micrometre (d) and sub-micrometre (e) Bi particles were observed to form on the surface. Scale bars: b-d, 2 μm; e, 500 nm; f,g, 5 μm.
