2. INTRODUCTION
• The first 2-dimensional material ever discovered.
• This leads to many properties that are electrically beneficial, such as
high electron mobility and lowered power usage.
• One-atom thick of carbon atoms arranged in a hexagonal lattice.

3. HISTORY
• Discovered by Andre Geim and Konstantin
Novoselov in 2004.
• Got 2010 Nobel prize for their pioneer
research in physics.
• Graphene was theoretically mentioned as
recent as 1984 to describe the layers of
graphite.

4. STRUCTURE
• GRAPHENE
• GRAPHITE
FULLERENE
• NANOTUBE
• ENERGY GAP

5. ELECTRICAL PROPERTIES
• Graphene is classified as a zero-
overlap semi-metal, which means that
either holes or electrons are charge
carriers.
• Very high electrical conductivity when
exposed to an electric field.
• In a vacuum, it had a mobility that was
up to 250X that of Si and conducts
copper by a thousand times.

6. MECHANICAL PROPERTIES
• Strongest material ever discovered
• Very light at 0.77 milligrams per
square meter, paper is 1000 times
heavier
• Single sheet of Graphene can cover a
whole football field while weighing
under 1 gram.
• ultimate tensile strength of 130 giga
Pascal compared to 400 mega Pascal
for structural steel.

7. 0PTICAL PROPERTIES
• Absorbs 2.3% white light
• Optical electronics absorb <10% white
light
• Highly conductive
• Strong and flexible

8. THERMAL PROPERTIES
• Graphene is a perfect thermal
conductor.
• It has higher thermal
conductivity than other carbon
materials.
• Higher thermal conductivity
leads to chips that are not only
faster but also better at
dissipating heat.

9. CHEMICAL PROPERTIES
• Chemically the most reactive
form of carbon.
• Can be used as both conductor
and semiconductor.
• High resistance to corrosion.

10. APPLICATIONS
Superconductor
•Due to high conductance.
•High tensile strength.
•Expandable up to 120% of
its length.

11. • Allows high current
densities.
• Improve the efficiency.
• Generation in night time
also.
Efficient solar power

12. Super capacitors and batteries
•Due to high energy density storage capacity.
•Huge scope for compact batteries
•Super capacitors can be made.

13. Flexible and compact electronics
•Length =1.2*Length.

14. Geothermal energy
• It has a capability of high thermal
conductivity.
• Alloy mixed Graphene can be use
to harvest Geothermal energy.

15. life of metals
• High resistance to corrosion.
• High mechanical strength.

16. OTHER APPLICATI0NS
Food preservation
by killing virus
Desalination
DNA studies
Light and strong
vehicles

17. SUMMARY & CONCLUSION
• Graphene, a singular layer of graphite, has
been discovered to have unique properties.
The high mobility and ability to travel short
distances without scattering makes it one of
the best materials for electrical applications.
Graphene mechanical and optical properties
also allow its use to go beyond electrical
applications.
