Abstract: | The eutectic alloy of BiInSn was ablated in water by UV pulsed radiation. Electron microscopy of the ablated material shows spherical particles that fall into three size regimes: those with diameters of ~0.5 μm, crystalline and amorphous particles with dimensions of ~30 nm, and amorphous particles that are approximately 1 nm across. The 30-nm amorphous particles are homogeneous, while there are two types of 30-nm crystalline particles, those that separate into three phases and those that are homogeneous. The existence of different characteristic sizes is explained by two mechanisms: phase explosion and Rayleigh instability of the ejected melt. |
