AB  - An organic film-assisted electrical breakdown technique is proposed to 
      selectively remove metallic (m-) single-walled carbon nanotubes (SWNTs) in full 
      length towards creation of pure semiconducting SWNT arrays which are available 
      for the large-scale fabrication of field effect transistors (FETs). The 
      electrical breakdown of horizontally aligned SWNT arrays embedded in organic 
      films resulted in a maximum removal length of 16.4 mum. The removal of SWNTs was 
      confirmed using scanning electron microscopy and Raman mapping measurements. The 
      on/off ratios of FETs were improved up to ca. 10,000, similar to that achieved 
      for in-air breakdown. The experimental results suggest that exothermic oxidation 
      of organic films induces propagation of oxidation reaction, hence the long-length 
      removal of m-SWNTs.
