一般說明

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.

商品

Graphene is a one-atomic-layer thick two-dimensional material made of carbon atoms arranged in a honeycomb structure. Its fascinating electrical, optical, and mechanical properties ignited enormous interdisciplinary interest from the physics, chemistry, and materials science fields.

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.

A transparent conductive electrode (TCE) is an essential component of various optoelectronic devices such as solar cells, liquid-crystal displays (LCD), light-emitting diodes (LED), and touch screens.
