일반 설명

Graphene is a unique one atom thick, two dimensional allotrope of carbon. Among all the synthesis technique, chemical vapor deposition of graphene on various substrates is the most promising route for the large scale production of good quality graphene. Graphene deposited on dielectric surface may exhibit better performance in graphene based FETs. Graphene deposited on quartz may be deposited by direct chemical vapor deposition via a sacrificial copper film.

Professor Gogotsi and Dr. Shuck introduce MXenes: a promising family of two-dimensional materials with a unique combination of high conductivity, hydrophilicity, and extensive tunability.

Advanced technologies for energy conversion and storage are widely sought after for their potential to improve consumer and electronic device performance as well as for the prospect of reducing the societal and environmental impact of energy generation.

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.
