FEAs are micr<strong>of</strong>abricated arrays <strong>of</strong> field emitters:<br />
• Can be made with and without gate<br />
electrodes<br />
• Additional self-aligned electrodes may be<br />
included <strong>for</strong> beam collimation to minimize<br />
emittance<br />
• Many varieties, including Spindt type, CNT,<br />
<strong>Diamond</strong> (DFEA) etc..<br />
ungated DFEA<br />
