Pressure dependence and current stability of field emission from carbon nanotubes on porous alumina

Abstract

Carbon nanotubes are synthesized by CVD using source precursors of metallocene related structures both on commercial and home made electrochemically etched porous alumina membranes of different thickness (60-200 /spl mu/m) and pore diameter (50-200 nm). AFM, SEM, EDX and TEM investigations showed that the tubular structures formed within the pores of the… (More)
