研究方向


房子是由砖块堆砌而成的,砖块与砖块之间由粘合剂把他们粘起来,其粘合强度在很大程度上决定了房子的牢固程度,而砖块与砖块之间的排列方式决定了建筑最后的样式和力学分布。类似于此,固体就是原子这种‘砖块’由自然界存在的力粘合起来,这种力让原子自动组装起来,该系统力学的分布方式让系统的能量最低(最稳固)。这种生成固体的方式是‘上帝之手’的杰作,是千百年来自然界中生成固体物质的方式。我把这类固体叫原子固体,来区分下面的纳米颗粒固体。

我的研究方向就是借助‘上帝之手’建造新的比原子更大块的‘砖块': 纳米颗粒。 然后寻找将纳米颗粒这些‘砖块’堆砌粘合起来的方法,从而制备人工的固体材料。由于其微观结构的不同,这些纳米颗粒固体材料具有有别于原子固体材料的性质,探讨其基本的物理性质,并且将其用在各种器件上,是我主要的研究兴趣。这些纳米颗粒‘砖块’的本征性质是由组成纳米颗粒的元素决定的,并且可以通过控制他们的大小、形状等参数来调节其性质。微细加工在这里是伟大的建筑师, 它可以设计出美妙的结构,将纳米颗粒这些‘砖块’堆砌成伟大的艺术品。由这些美妙的结构派生出来的奇特性质和用途,更是美妙绝伦。
