                         featuring high specific surface area have been prepared by 
                         plasma-enhanced chemical vapour deposition (CVD) onto densely 
                         packed forests of vertically aligned multiwall carbon nanotubes 
                         (VACNTs). The DLC:VACNT composite film exhibits a complex 
                         topography with web like features and ridges generated by partial 
                         coalescence of the DLC over the CNT arrays. DLC:VACNT electrodes 
                         exhibit low background responses over a large potential window, 
                         low uncompensated resistance, as well as low charge-transfer 
                         impedance in the presence of ferrocyanide as a redox probe. The 
                         interfacial capacitance associated with the DLC:VACNT electrode is 
                         in the range of 0.6 mF cm(-2), a value two orders of magnitude 
                         larger than in conventional flat carbon electrodes. DLC films 
                         grown onto single-crystal Si(100) under identical conditions 
                         resulted in essentially insulating layers. Conducting-atomic force 
                         microscopy studies reveal that the film electro-activity does not 
                         arise from specific topographic features in the highly corrugated 
                         film. The ensemble of experimental results suggests that the 
                         enhanced electrochemical responses are not connected to areas in 
                         which the CNT support is exposed to the electrolyte solution. This 
                         is remarkable behaviour considering that no dopants have been 
                         included during the DLC film growth.",
