在20世纪的最后十年,一门崭新的学科—纳米科学技术以其新颖性、独特的思路和首批研究成果的问世,在科学技术界和军界引起巨大反响,受到广泛关注。美国IBM公司首席科学家Amotrong说:“正如70年代微电子技术引发了信息革命一样,纳米科学技术将成为下一世纪信息时代的核心。”
从幻想到现实:
50年代末著名的物理学诺贝尔奖获得者R.Feynman曾指出,科学技术发展的途径有两条,一条是“自上而下”的过程。另一条是“自下而上”的过程。近几十年来,科学技术一直沿着“自下而上”的微型化过程发展。纳米科学技术专家们相信“自下而上”的途径,即从原子、分子开始组装具有特定功能的成品,例如在一定物理化学条件下,通过自组织效应,生长具有纳米结构特征的半导体薄膜;形成超强度材料;制备量子点结构器件等,都是“自下而上”方法的实例。

In 20th century finally ten years, a brand-new discipline -- nanometer science and technology by its novel, the unique mentality and first batch research results being published, and the military circles causes the giant echo in the science and technology, receives the widespread attention. American IBM Corporation chief scientist Amotrong said that, "Just like the 70's micro electrons technology initiated the information revolution to be same, the nanometer science and technology will become the next century information time the core."
From fantasizes to the reality:
At the end of 50's famous physics Nobel prize winner R. Feynman once pointed out that, the science and technology development way has two, was "from the top downward" process. Another is "from bottow to top" process. In the recent several dozens years, science and technology continuously along "from bottow to top" microminiaturized process development. The nanometer science and technology experts believed "from bottow to top" the way, namely from the atom, the member starts to assemble has the specific function the end product, for example under the certain physical chemistry condition, through from the organization effect, the growth has the nanometer structure characteristic the semiconductor thin film; Forms the ultra intensity material; The preparation quantum Spot structure component and so on, all is "from bottow to top" the method example.
