Concept Info

NAME

Graphene

DESCRIPTION

Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure. Its properties include high strength and good conductivity of heat and electricity. The stacked form of graphene is graphite.

68 skos:definition Nanoscale materials, or nanomaterials, are materials where at least one relevant length scale is within the range of nanometres. These materials usually have very different properties from their bulk counterparts, due to the importance of quantum and surface boundary effects.

91 skos:definition Nanoscience and technology is the branch of science that studies systems and manipulates matter on atomic, molecular and supramolecular scales (the nanometre scale). On such a length scale, quantum mechanical and surface boundary effects become relevant, conferring properties on materials that are not observable on larger, macroscopic length scales.

109 skos:definition Optical materials and structures are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.
