APPLICATION NOTE Graphene and Graphene Oxide

ABSTRACT Graphene and graphene oxide layers are localized and charcterized on different sub- strate materials by means of the spectroscopic imaging ellipsometer nanofilm ep3se. The thickness and the dispersion functions of the refractive index n and of the extinction k of a few µm-wide layers are obtained.

Optical Properties of Graphene from the THz to the Visible

In this thesis, two models are developed to describe the optical properties of graphene from the THz to the visible spectral region. We show that the optical conductivity is mainly contributed by interband carrier transitions in the visible region and by intraband carrier scattering in the THz range.

Graphene Oxide – What Is It? – Graphenea

The main difference between graphite oxide and graphene oxide is, thus, the number of layers. While graphite oxide is a multilayer system in a graphene oxide dispersion a few layers flakes and monolayer flakes can be found.

Sensitive Real-Time Monitoring of Refractive Indexes Using

A graphene refractive index sensor can quickly and sensitively monitor changes in the local refractive index with a fast response time and broad dynamic range. These results indicate that graphene, used in a simple and efficient total internal reflection structure and combined with microfluidic techniques, is an ideal material for fabricating
