Recent advances in nanotube synthesis have allowed the growth of large areas of aligned nanotubes. Fan et al. (p. 512) have moved a step further by showing that through catalyst patterning of the surface prior to nanotube growth, patterns of nanotube blocks can be fabricated with a high degree of control. These blocks are shown to have advantageous electron field emission characteristics, such as low operating voltages and high current stability, that could be used in devices.
