自80年代起,人们开始从科技刊物及新闻报导中不断接触“纳米科学”,“纳米技术”,“纳米加工”等新鲜名词。对于这些由科学家与工程师们发明的新名词和它们所代表的新领域,大多数读者一定是充满了生疏感与好奇感。 什么是纳米科学与技术?它们研究的对象是什么?这一技术已取得什么成就并且会应用在哪些方面呢?本文将简要地回答这几个问题。 随着人们对物质结构向更深层次的了解,科学工作者将目光逐步缩小到微观世界。以我们熟知的半导体晶 Since the 1980s, people began to make constant contact with such new nouns as “nanoscience”, “nanotechnology” and “nano-processing” from scientific journals and news reports. For these new terms invented by scientists and engineers and the new areas they represent, most readers must be full of sense of strangeness and curiosity. What are nanoscale sciences and technologies? What are their research targets? What are the achievements and applications of this technology? In this article, we will briefly answer these questions. As people understand the material structure to a deeper level, scientists gradually reduce their attention to the micro-world. We know the semiconductor crystal
