Introduction to Graphene
"Graphene" is a combination of graphite and the suffix -
ene, named by Hanns-Peter Boehm.It’s a 2-D ,crystalline
allotrope of Carbon. It can be described as one atom thick
layer of graphite.

The Nobel Prize in Physics for 2010 was awarded to Andre Geim
and Konstantin Novoselvo at the University of Manchester.
Technique used by them to evolve single layer of graphene was
scotch tape technique.

Structure of Graphene
The atomic structure of isolated, single layer graphene was
studied under TEM on a sheet of graphene suspende
between bars of metallic grids.
Result of electron diffraction pattern is a honeycomb lattice
The flat sheet of graphene is having amplitude of about 1
Carbon to Carbon bond length in graphene is about 0.142

Properties of Graphene
Thinnest ,200 times stronger than steel.Its youngs modulus
is 0.5 Tpa.
Its 97.3% transparent and so dense that not even helium can
pass through it.
Lowest resistivity substance known at room temperature
Its 20% flexible.
High electrical conductivity.
Unbreakable to some extent.
High thermal stability .
Electron mobility is high at room temperature. 6
Comparison of graphene Vs sillicon
1.Break over voltage is less
than 0.3 v.
1.Break over volatge is 0.3 v.
2.Electron transfer is 200
times faster .
2.Electrons transfer is slower.
3.Zero band gap energy. 3.Band gap energy is 1.1 v
4.Its flexibility is high. 4.Flexibility is lower than
5.Its unbreakable . 5.Its breakable.
Why Graphene Mobile phones ?
Graphene a super wonder material with wide range of propeties
better than other semiconductor materials .
From past few years scientist have shown tremendous and fast
growth in the graphene made devices and there applicability in
broad range from Medical field , mechanical ,electronics and
may more to go in future.
1 year back IBM launched the graphene based transistor. Great
companies like Nokia, samsung are already indulged in project
for making graphene mobile phone.

Mobile phones made of graphene are highly flexible and light
It replaces ITO screens which are brittle and expensive by
Organic Light emitting diode of single layer graphene.
Batteries used are flexible and liquid batteries which are light in
weight and longer life.
High speed device with ultra slim structure and easy to carry in
our pockets or wear as wrist watch.
Nokia is soon going to launch its Nokia morph and Nokia 880.
which can change its shape according to the message which user
want to send.
In nokia morh the display is touch screen,with large memory

Graphene mobile phones Vs. Smart
Graphene mobile phones are lighter than smart phones.
Slimmer body .
Having High speed internet as graphene is combined with
mettalic nanostructre.along with high communication rate.
Much safer touch screen display as it does not uses
ITO(which is breakable).
Better camera sensors more than 41mp camera based on
Having ligh weight flexible batteries with longer life which
is the major proble we are facing today.
Highly transparent structure.
Heat dissipation in graphene phones would be less.
Graphene phone protoype doesn’t not have memory card
slot ,while smart phones have it .
No facilities of Bluetooth or data cable is provided in the
Conclusions and future scope
Graphene is new hope for electronic device and replace
and rejunivate sillicon .
The cost of garphene phones would be high but it will be
available with few distinct feautres .
In future the graphene phones would might be connected
with laptops without any device .
The facilitiesof data cables ,headsets, bluethooth would
also be implied.
