Multiwalled carbon nanotubes (MWNTs) were homogeneously dispersed into aluminum (Al) powder by the elastomer precursor method. MWNT/Al composites were prepared by extrusion molding of the precursor powder and cut into thin plates. Each composite plate was split parallel or perpendicular to the extrusion direction, and used for field emission measurements. The perpendicular cross section exhibited excellent electron emission with a threshold electric field of 2.0 V/μm and a current density of 1.5 mA/cm2 since a considerable number of oriented MWNTs were sticking out of the cross-sectional surface. With those oriented MWNT/Al composite emitters, a flat-panel field emission lamp (FEL) was successfully fabricated by using the side-electron emission device (SEED) structure.
