Abstract

We show that partial inhibition of the emerging Ag domain can be achieved by controlling the growth dynamics. With the symmetry broken by the "fresh" surface, sequentially growth gives (Au sphere)-(Ag wire)-(Ag plate) triblock nanostructures. This new understanding opens doors to sophisticated synthetic designs, broadening the horizon of our search for functional architectures.

摘要

我们表明，通过控制生长动力学，可以实现新兴 Ag 域的部分抑制。通过“新鲜”表面打破对称性，顺序生长得到（Au 球）-（Ag 线）-（Ag 板）三嵌段纳米结构。这种新的认识为复杂的合成设计打开了大门，拓宽了我们寻找功能结构的视野。
