Graphene - Y-Prize Competition
Transcript of Graphene - Y-Prize Competition
What is Graphene?● Graphene is a single atom
thick material made entirely of carbon atoms arranged in a honeycomb lattice.
● Discovered by exfoliating a graphene flake repeatedly.
● It can form materials of all dimensionalitieso Fullerenes (0D)o Nanotubes (1D)o Graphene (2D)o Graphite (3D)
What are the properties?● Graphene’s strength come
from it’s covalent bonds. Strongest chemical bonds between atoms.
● Graphene’s amazing properties come from it’s linear dispersion.
● In graphene electrons behave with zero effective mass.
● High electron mobility.o High electric
conduction.o High thermal
conduction
How about large scale?Roll-to-roll graphene
1. Enables mass production of graphene.a. Roll of copper is loaded into a furnace, with a
roll of graphene covered copper coming out.b. Roll of graphene covered copper is coated
with PET polymer.c. Roll of PET/Graphene/Copper and is sprayed
with copper chloride etchant.d. Final roll or graphene on PET is produced.
