The emission characteristics follow a Fowler-Nordheim process over more than 10 orders of magnitude before reaching saturation and the angular emission intensities reach hundreds of \u03bcA\/sr. The applied external electric field is of the order of one V\/\u03bcm, which for a cold emission process is very surprising. Typically, field emission requires fields of a few V\/nm.We are interested, both in the potential applications of this process but also in the fundamental understanding of the mechanisms involved.<\/p>\n<\/div>\n<\/div><\/div><\/div><div id=\"pgc-9074-0-1\"  class=\"panel-grid-cell\" ><div id=\"panel-9074-0-1-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"1\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-editor so-widget-sow-editor-base\"\n\t\t\t\n\t\t>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n\t<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-9094\" src=\"http:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/07\/12-Salancon1Celadonite-75x50.jpg\" alt=\"\" width=\"945\" height=\"630\" srcset=\"https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/07\/12-Salancon1Celadonite-75x50.jpg 945w, https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/07\/12-Salancon1Celadonite-75x50-300x200.jpg 300w, https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/07\/12-Salancon1Celadonite-75x50-768x512.jpg 768w, https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/07\/12-Salancon1Celadonite-75x50-272x182.jpg 272w\" sizes=\"(max-width: 706px) 89vw, (max-width: 767px) 82vw, 740px\" \/><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Contact: E.
