The company\u2019s first device will be available in the next few months.<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">Graphene\u2019s remarkable properties \u2013 stronger than steel, more conductive than copper, highly flexible and transparent \u2013 make it ideal for a range of applications. However, its widespread commercial application in electronic devices has been held back by the difficulties associated with producing it at high quality and at high volume. The conventional way of making large-area graphene involves using copper as a catalyst, which contaminates the graphene, making it unsuitable for electronic applications.<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">Professor Sir Colin Humphreys from the Centre for Gallium Nitride in Cambridge\u2019s Department of Materials Science and Metallurgy, along with his former postdoctoral researchers Dr. Simon Thomas and Dr. Ivor Guiney, developed a new way to make large-area graphene in 2015.<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">Using their method, the researchers were able form high-quality graphene wafers up to eight inches in diameter, beating not only other university research groups worldwide, but also companies such as IBM, Intel, and Samsung.<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">The three researchers spun out Paragraf in early 2018.
