Dr. H. Sugime and Mr. T. Osawa are thanked for their technical support and Mr. Y. Sato is thanked for the TEM observation. Cr microelectrodes (for Libraries 1−3 and Samples 1 and 2) were fabricated and TEM observation was conducted at the Centre for Nano Lithography and Analysis, The University of Tokyo, supported by MEXT. Mr. Y. Obara (Futaba Co.) is thanked for providing alkali-free glass substrates with Nb microelectrodes (for Samples 3 and 4). This work was financially supported by KAKENHI (Nos. 19054003 , 21686074 , and 21760003 ) from MEXT, Japan and PRESTO (No. 3130 ) from JST, Japan.

N2 - We report the very rapid growth of carbon nanotubes (CNTs) at high temperatures that can be tolerated by glass substrates. Glass substrates with metal microelectrodes and sputtered catalysts are heated by a pulsed current in a chemical vapour deposition gas environment for 0.5-1 s to synthesize CNTs of several micrometres in height without damaging the glass substrate. CNTs with structures from single-walled to multi-walled and morphologies from entangled networks to vertically aligned forests are grown simply by changing the nominal thickness of the catalyst, and such CNTs grown selectively on the microelectrodes worked as field emitters for cathodoluminescence. Rapid, easy growth of patterned CNT arrays on glass substrates without using furnaces/heaters or vacuum pumps will be useful for various applications of CNTs.
