Planar field electron emitters containing carbon nanotubes that demonstrate stable emission currents with densities about 1 A/cm 2 have been fabricated using the chemical vapor deposition method. The analysis of field emission characteristics based on Fowler-Nordheim theory allowed one to calculate
We have achieved selective growth of high-purity carbon nanotubes (CNTs) on iron-deposited hole-patterns by thermal chemical vapor deposition (CVD) of acetylene gas. The vertically well-aligned CNTs were uniformly synthesized with good selectivity on hole-patterned silicon substrates. The CNTs indic
