Professor HONG Byung Hee (Dept. of Chemistry)
Professor HONG Byung Hee HONG (Dept. of Chemistry) and Samsung Techwin have developed a way to mass produce graphene and apply it to smartphones. Graphene has high electrical conductivity and so was expected to be used in manufacturing electronic goods. However, there were problems in size, uniformity and stability which stopped it from being widely used. Professor Hong used rapid thermal chemical vapor deposition (RT-CVD) technology to develop graphene film over 400×300㎟ wide. This technology allows graphene to be produced in a mere 40 minutes whereas it previously took 300 minutes to produce the same amount. Samsung Techwin applied this graphene film to their smartphones’ multi-touch screen and remarked that they have affirmed the possibility of mass producing smartphones using graphene.
