    In this letter, we report a process for room-temperature assembly of patterned and periodic structures of carbon nanotubes (CNTs). Well-defined patterns with less than a 10-µm linewidth and variable thickness were readily deposited. The CNTs show long-range in-plane orientation ordering and...

    We show that the field of application of cold electron film emitters can be extended to nonplanar geometries by demonstrating a cylindrical field emission diode. The cathode is a metallic wire on which multiwall carbon nanotubes are grown by the catalytic decomposition of acetylene over a Fe...
