一般說明

方块电阻测量在真空室中进行,在四点结构(范德堡法,银漆接触)内注入超过 10uA的电流以确保其可重复性
石墨烯是一种独特的单原子厚度的石墨,以二维结构存在的碳的同素异形体。在所有合成技术中,石墨烯在各种基质上的化学气相沉积是大规模生产高质量石墨烯的最有前景的方法。 沉积在介电表面上的石墨烯在石墨烯FET中可能会表现出更好的性能。可以利用牺牲层铜薄膜通过直接化学气相沉积,使石墨烯沉积在SiO2/Si上。

Graphene, a two-dimensional monolayer of sp(2)-bonded carbon atoms, has been attracting great interest due to its unique transport properties. One of the promising applications of graphene is as a transparent conductive electrode owing to its high optical transmittance and conductivity.

文章

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.
