题目:Chemical routes to top-down nanofabrication
摘要:In fabricating materials at the nanometer scale, nanotechnologists typically employ two general strategies: bottom-up and top-down. While the bottom-up approach constructs nanomaterials from basic building blocks like atoms or molecules, the top-down approach produces nanostructures by deconstructing larger materials with the use of lithographic tools (i.e., physical top-down) or through chemical-based processes (i.e., chemical top-down). This tutorial review summarizes the various top-down nanofabrication methods, with great emphasis on the chemical routes that can generate nanoporous materials and ordered arrays of nanostructures with three-dimensional features. The chemical top-down routes that are discussed in detail include (1) templated etching, (2) selective dealloying, (3) anisotropic dissolution, and (4) thermal decomposition. These emerging nanofabrication tools open up new avenues in the creation of functional nanostructures with a wide array of promising applications.
介绍:Chem. Soc. Rev. 的TUTORIAL REVIEW.一般来讲,纳米材料合成的方法基本分为top to down (利用大颗粒的原料合成纳米结构的材料)和down to top (利用本身就很小的纳米材料组装成具有纳米结构的材料)两种。down to top是我们比较熟知的,可是关于top to down的合成方法你知道多少呢?本文作者通过几个实例,深入浅出,值得一读。五星推荐。
