“…It is worth noting that when the thermal conductivity of the eutectic materials matches that of the template, the thermal gradient also remains predominantly vertical. Since achieving an exact match in thermal conductivity is challenging, [36][37][38][39] a thermal insulating template provides a more practical solution for maintaining a predominantly vertical thermal gradient. Within a thermal insulating template, the horizontal component of the thermal gradient (taken here as the x component, as described in Figure 2a) remains small throughout the vertical axial span of the pillar, from the upper (pillar top) to the lower (pillar bottom) end of the pillar (blue curve, Figure 2c), in contrast to the high thermal conductivity template where the horizontal component of the thermal gradient is significant (red curve, Figure 2c).…”

Template‐directed self‐assembly of solidifying eutectics results in emergence of unique microstructures due to diffusion constraints and thermal gradients imposed by the template. Here, we demonstrate the importance of selecting the template material based on its conductivity to control heat transfer between the template and the solidifying eutectic and thus the thermal gradients near the solidification front. Simulations elucidate the relationship between the thermal properties of the eutectic and template and the resultant microstructure. The overarching finding is that templates with low thermal conductivities are generally advantageous for forming highly organized microstructures. When we use electrochemically porosified silicon pillars (thermal conductivity < 0.3 Wm−1K−1) as the template into which an AgCl‐KCl eutectic is solidified, 99% of the unit cells in the solidified structure exhibit the same pattern. In contrast, when higher thermal conductivity crystalline silicon pillars (∼100 Wm−1K−1) are utilized, the expected pattern is only present in 50% of the unit cells. The thermally engineered template resulted in mesostructures with tunable optical properties and reflectances nearly identical to the simulated reflectances of perfect structures, indicating highly ordered patterns are formed over large areas. Our work highlights the importance of controlling heat flows in template‐directed self‐assembly of eutectics.This article is protected by copyright. All rights reserved
