H. Fudouzi et al., DRAWING AND OBSERVATION OF ELECTRIFIED IM AGES ON CERAMIC SUBSTRATES USING ELECTRON-BEAM, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 104(6), 1996, pp. 556-561
Main process of the powder particles' assembly, proposed for creation
of multi-functional materials, consists of drawing electrified pattern
s on substrates and introducing electrified powder particles onto the
substrates, In the process, the powder particles are arranged along wi
th the patterns by electrostatic force, In the present paper, electrif
ication behaviors on ceramic substrates was studied. Electrified image
s were formed on calcium titanium oxide (CaTiO3) substrates using elec
tron beam. The substrates were positively electrified by 1 kV electron
beam, while the substrates were negatively electrified by electron be
ams with 3 kV and higher voltages, Electrified images were observed by
the voltage contrast method using 2 kV electron beam scanning, Sharpn
ess of electrified images were influenced by the condition of electron
exposure, Sharp images were obtained by the electron beams with dose
electron density of 0.2 pC/mu m(2) and accelerating voltage of 5-15 kV
, The electrified images disappeared after Ih in air, but were maintai
ned for 62h in vacuum.
