A crystalline graphitic structure—uniform diameter, thin-walled carbon microtubes (see Figure)—has been prepared via a thermal reaction between ZnS and activated carbon. The microtubes have outer diameters of ∼ 1–2 μm, wall thicknesses of 10–20 nm, and lengths from several hundreds of micrometers to millimeters. The field-emission turn-on of the carbon microtubes is as low as ∼ 1.0–1.3 V μm–1.
