纳米给人的新希望 拥有一台只有手掌大小的超级电脑或许仍是个遥不可及的梦想,不过来自美国及荷 兰的最新研究结果,使人们朝这个目标迈出了重要的一步。 当你我可能还为着广告中那即薄又轻的笔记型电脑钦羡不己的时候,科学家早已把 目光放在纳米尺度的电子元件上。虽然早在1974年, aviram和 Ratner便提出了分子级 电子元件( molecular electronic device)的概念,直到最近几年,科学家才知道如何以碳纳 米管( carbon nanotube)、纳米线( nanowire)或有机分子建构导线、开关等单一电子元 件 而根据在几周前的 Science的一篇文章,荷兰 Delft University of Technology的ces Dekker所带领的研究小组已成功地利用碳纳米管制作了好几种数位逻辑运算电路
