Abstract :
In this work, the field emission property of wide band gap material (WBGM)-coated carbon nanotubes. The secondary electron emission behavior of MgO- and MgO/CsI-coated nanotubes were also investigated. The high secondary electron emission yields may be ascribed to the geometrical effect of the MgOand MgO/CsI-coated SWNTs
