那最幸福的时刻，莫过于当我们第一次在显微镜下观测到，用新方法制备出来的晶体排列得整整齐齐 时，那种震撼无法言喻。 2025年，我们将自主首创的晶体制备方法应用到光学晶体生长领域。通俗地说，就是用一种类似"顶竹 笋""拧魔方"的方法，让光学晶体生长，得到了一种"超薄转角光学晶体"。 作为一个研究凝聚态物理的科学家，这一年，最艰难的时刻莫过于要推翻全世界沿用的传统理论，承认 旧路走不通，在迷雾中寻找新方向。 这是制备的氮化硼光学晶体照片，照片中间长方形的样品区域是氮化硼材料。新华社发（作者供图） 这些名词是不是听起来一头雾水？这就是我写这篇科普文章的目的，就是告诉大家：基础科学研究很有 趣，它就在我们身边。 比如，什么是凝聚态物理？这个词儿听起来很高深，其实它就是研究微观粒子如何"排队"的学问，就像 水分子"听指挥"整齐排列就能结成冰一样。 什么叫晶体？它是计算机、通信、航空、激光技术等领域的关键材料。过去几十年，国际上通用的造晶 体方法，就像是"盖房子"——这相当于先铺好地基（晶种），然后把原子一块块搬运过来，在表面一层 层垒上去。 这种方法有个致命弱点：楼层一旦盖高了，稍微有一块砖没对齐，后面就会跟着歪，甚至 ...
