Screening Effect<br />
High site density (>109 /cm2 )<br />
leading to small electrical<br />
enhancement at the tips. A site<br />
density of about 107 /cm2 (according to electrostatic<br />
calculation) has been<br />
calculated to be the right<br />
number for optimal electron<br />
emission properties in the<br />
sense of both emission site<br />
and current density.<br />

Patterns with both in micro-scale and nano-scale for the CNT<br />
arrays have been expected to reach high-field-emission<br />
capability and uniformity.
