Founder’s Message

Thank you for visiting our website. Graphene Square Inc. (GSI) was founded in January 2012 based on the world's first CVD graphene sythesis technology published in Nature (2009) and Nature Nanotech. (2010). To date, we have successfully secured 80+ graphene related patents. In particular, GSI has the key patents on the industrial scale production technolgy as highlighted by Bloomberg (2014). We have been working with large electronics company such as Samsung, LG, and Apple for many years, and realized that the future of electronics cannot be realized without graphene, and GSI has a unique position that brings the graphene and 2D materials technology to our real life based on its strong IP portfolio including R2R production, EMI sheilding, touch screen, transparent heaters, etc.

Founder/Scientific Advisor

Pioneer of large-scale graphene synthesis Byung Hee Hong pioneered the large-scale synthesis of graphene by CVD(Chemical vapor deposition) from previously micrometer scale level, which triggered chemical research studies toward the practical applications of graphene.

  • Meter Scale <Graphene Finally Goes Big> Science (2010)
  • Unlimited Scale <Now Graphene Goes Limitless> (2016)
In terms of graphene research, even though graphene was discovered by Geim&Novoselov, Byung Hee Hong is evaluated as the frontier with respect to its commercialization
World’s first reporter of …
  • CVD synthesis One of 2 essential methods of graphene synthesis

    His first report on the CVD synthesis of graphene
    (Nature 457, 706 (2009)) has recorded the world highest citations in chemistry among the papers published since 2009.

    6,000+ citation as of today (2009~)  
  • R2R method Ultimate technology for graphene mass production

    A year after, Byung Hee Hong developed the synthesis of ultra-large graphene based on roll-to-roll method and applied the material to flexible touch screens (Nature Nanotech. 5, 574-578 (2010)), which is believed to be the first demonstration of the utilization of graphene materials in practical electronic devices. 

    4,000+ citation as of today (2010~)  
Nobel Symposium & Nobel Museum

For this contribution, Byung Hee Hong was invited by the Nobel Committee to give a presentation in the Novel Symposium on Graphene, five months prior to the announcement of the Nobel Physics Prize on graphene in 2010. The press release by the Royal Swedish Academy has cited Byung Hee Hong’s paper as one of the major research achievements that contributed to the prize, and his achievements are being exhibited in *Nobel Museum.

* Nobel Museum

Located in Stockholm Sweden, Nobel museum is a museum devoted to circulate information on the Nobel Prize, Nobel laureates from 1901 to present, and the life of the founder of the prize, Alfred Nobel (1833-1896).

    “In my opinion, Korea’s graphene research is at the forefront. Byung Hee Hong first developed the technique to produce graphene in mass scale and it was quite innovative. He changed people’s perspective of graphene. Within the labs, graphene was a fun and interesting research area material, but then suddenly, it was transformed into something that we can actually apply and adapt.”- 2015 KBS “Carbon Revolution” -

Professor Kim is a world leading scientist in the area of materials research. His research area is experimental condensed matter physics with an emphasis on physical properties and applications of nanoscale low-dimensional materials.  The focus of Prof. Kim’s group research is the mesoscopic investigation of transport phenomena, particularly, electric, thermal and thermoelectrical properties of low dimensional nanoscale materials. These materials include carbon nanotubes, organic and inorganic nanowires, 2-dimensional mesoscopic single crystals, and single organic molecules. The use of modern state-of-the-art semiconductor device fabrication techniques and the development of new methods of material synthesis/manipulation are essential parts of this research. He has initiated these efforts very successfully, and is continuously making innovations in microscopic experimental tools and methods in order to investigate the electric, thermal/thermoelectric transport properties of the nanoscale materials. Professor Kim published more than 120 papers in professional journals which are well cited. Many of his papers are published in high impact journals such as Nature, Science and Physical Review Letters. Professor Kim received numerous honors and award including Oliver E. Buckley Prize (2014), Loeb Lectureship, Harvard (2012); Dresden Barkhausen Award (2011); Yunker Lectureship, Oregon State University, (2011); Chapman Lectureship, Rice University, (2009);  IBM Faculty Award (2009); Ho-Am Science Prize (2008); American Physical Society Fellow (2007); Columbia University Distinguished Faculty Award (2007); Recipient Scientific American 50 (2006); National Science Foundation Faculty Career Award (2004).  In addition, He has given more than 300 invited presentations as keynote speaker, plenary speakers, and invited speakers in international and domestic conferences, colloquiums and department seminars.
