The magic of graphene itself is not enough. For the sensor to operate stably at very high temperatures, around 500\u00b0C, something extra is needed. Meaning: the substrate on which it was grown should be modified. Or, more precisely, the ladder of its energy levels.<\/p>\n<p>So what needs to be done? We have to remove the rungs that harm the sensor. Important! When talking about energy rungs, we mean electron traps. A well-designed ladder is jagged, but this makes the sensor less susceptible to temperature variations. And that&#8217;s it!<\/p>\n<p>Our new article published in Elsevier Carbon Trends talks about the removal of rungs of the energy ladder, i.e., the defect engineering in the epitaxial graphene on silicon carbide system: <a href=\"https:\/\/www.researchgate.net\/publication\/374702659_Defect-engineered_graphene-on-silicon-carbide_platform_for_magnetic_field_sensing_at_greatly_elevated_temperatures\"><span style=\"color: #44d62c;\"><strong>https:\/\/www.researchgate.net\/publication\/374702659_Defect-engineered_graphene-on-silicon-carbide_platform_for_magnetic_field_sensing_at_greatly_elevated_temperatures<\/strong><\/span><\/a><\/p>\n<p>\u2139 The article is the culmination of the scientific and technological efforts within the NCN OPUS and M-ERA.NET I4BAGS projects.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8220;It is only with the [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":15641,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_lmt_disableupdate":"no","_lmt_disable":""},"categories":[86,653],"tags":[1038],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.13 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Graphene-based Magnetic Field Sensors<\/title>\n<meta name=\"description\" content=\"The magic of graphene itself is not enough.
