    A large area arrays (ca. 40 cm2) of CdS nanotube on silicon wafer are successfully fabricated by the method of layer-by-layer deposition cycle. The wall thicknesses of CdS nanotubes are tuned by controlling the times of layer-by-layer deposition cycle. The field emission (FE) properties of CdS...

    Carbon-nanotube tips are plastically deformed during field emission. High-resolution transmission electron microscopy and structural simulations suggest that the deformed structure of the closed nanotube is explained by heterogeneous nucleation of the pentagonal and heptagonal carbon ring pairs,...

    We report on the direct observation of the growth of nanoprotrusions on iridium field-emission tips. For clean, protrusion-free field emitters, the field emission originated from crystal planes with low-work-function values. However, with continuous operation, we observed the growth of...

    We compare the field emission characteristics of dense (10[sup 9]nanofibers/cm²), sparse (10[sup 7] nanofibers/cm²), and patterned arrays (10[sup 6] nanofibers/cm²) of vertically aligned carbon nanofibers on silicon substrates. The carbon nanofibers were prepared using plasma-enhanced...

    Nanowires are grown from a cold-field-emission tip in the presence of a precursor, typically an organometallic or organic compound. Electron emission from the newly grown nanowire tip continues the growth and can give rise to nanowires that are tens of microns long. Single nanowires are obtained...
