Prof. Tae-woo Lee (MSE) announced that his team succeeded in making a large-area graphene nanoribbon cheaply and quickly on Apr. 27. This research result was published in Advanced Materials on Apr. 10.Graphene, called the material of dreams, is stronger than steel and has high electrical conductivity. However, it cannot control a state of electron energy, which limits its usefulness in semiconductor devices. Graphene nanaribbon can solve this problem but production was difficult because of the time re News | Reporter Park Min-young | 2014-05-21 15:12 A New Way to Tune the Band Gap in Quantum Dot A New Way to Tune the Band Gap in Quantum Dot Quantum dot is used in various products such as displays and medical devices but had difficulty in tuning band gap. A POS- TECH research team announced a new tech- nology that can handle tuning band gap on the cover of the April edition of Small. By using the phase transition of quantum dot, Eui-hyun Kong (MSE Ph.D., advisor Prof. Hyun Myung Jang) and his team successfully developed technology that enables two phases to coexist in a single quantum dot. With this technology, the optical property of electrodes increases so much that quantum dot-sensitized solar cell’s efficiency can be improved News | Reporter Park Min-young | 2014-04-30 17:50 Essential Things that I will Keep in Mind Essential Things that I will Keep in Mind If I join The Postech Times, I think the most important thing to have is responsibility. As a representative The Postech Times, I will do my best with a strong sense of duty. I think it is important that I have to have the objective attitude as a reporter of POSTECH when I write the newspaper. There will be many things that can be written in a newspaper. Because I want to write articles that are related to people around me, it is easy to write an article with subjective feelings. Nevertheless, I will be more objective when I actually write the articles.In order to develop the newspaper, there Opinion | Reporter Park Min-young | 2014-04-09 15:23 처음처음이전이전12345끝끝
