摘要：

Layers (similar to 1 mu m thick) of crooked carbon nanotubes 20-60 nm in diameter were obtained at 800 degrees C by pyrolysis of polyethylene in He atmosphere using a Ni plate as a catalytic substrate. They were identified by electron microscopy and electron diffraction. Tips of some tubes (similar to 10(6)/cm(2)) come out of the layer. We studied their field electron emission at 10(-9) torr vacuum. 1-10 mA/cm(2) current density was observed at 4-10 V/mu m (V similar to 100-250 V). (C) 1998 Elsevier Science Ltd.
