世界各国一百多个实验室的科学家们在争先恐后地利用一项可开创新技术领域的工艺,其制造材料的方法极其精细,可一层原子一层原子地制造新材料。这一无比精密的方法称为“分子束晶体附生法(Molecular beam epitaxy)”,大致类似于用原子或分子缓慢地喷涂。科学家们可以用仅有两个原子厚的一层材料涂覆晶体表面,然后再在它上面涂一层 Scientists in more than 100 laboratories around the world are scrambling to utilize a process that opens up new fields of technology. The method of making materials is extremely fine, making new materials atomically atom by atom. This immensely sophisticated method, called “molecular beam epitaxy,” is roughly similar to spraying slowly with atoms or molecules. Scientists can coat the crystal surface with a layer of material that is only two atoms thick, and then coat it with a layer of
