Graphene: Introduction and Properties

Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is the basic building block of other carbon allotropes, such as graphite, carbon nanotubes, and fullerenes. Graphene has unique and remarkable properties, making it a subject of intense scientific research and technological interest.

Properties of Graphene:

High Electrical Conductivity: Graphene exhibits exceptional electrical conductivity, making it a promising material for electronic and optoelectronic applications.
High Thermal Conductivity: It also possesses high thermal conductivity, which is beneficial for thermal management in various devices.
Mechanical Strength: Graphene is incredibly strong, yet lightweight, making it an ideal material for structural applications.
Transparency: It is transparent and absorbs only around 2.3% of light, making it suitable for transparent conducting films and touchscreens.
Flexibility: Graphene is flexible, allowing it to be integrated into flexible electronics and wearable devices.
