BACKGROUND From source 1 • Graphene is a material made of carbon atoms in sheet form.1 • It is so thin that it is often considered two-dimensional. • It is “widely cited as the strongest material ever created on a per-weight basis, but it also has incredibly high electrical conductivity.”1 (extremetech.com) 1 Templeton, Graham. (2015) What Is Graphene?, extremetech.com SIGNIFICANCE • Graphene’s small size but strong conductivity open many doors for electronic industries ...
Outline • Introduction • History • Structure • Properties • Application in Various Fields • Advantages and Limitations • Recent developments • Future Applications • Conclusion introduction • What is Graphene? – Graphene is a single thin layer of graphite – It is an allotrope of carbon – It is tightly packed layer of carbon atoms – Its Atoms are arranged in a hexagonal pattern and resembles that of a honeycomb lattice – It is one atom thick and the ...
