Scratching the surface : A simple needle‐scratching method (NSM) generates large‐area catalyst patterns on solid substrates for the growth of densely aligned single‐walled carbon‐nanotube (SWCNT) arrays by chemical vapor deposition (CVD, see picture). A high density of well‐aligned, ultralong SWCNTs is obtained on single‐crystal quartz. This NSM could allow the fast, cheap, and large‐area fabrication of CNT‐based nanodevices.
