2.1.3.nano technology era (october 2004 onward)

[A new class of materials Two-dimensional(2D)crystalline materials have recently been identified and analyzed (1). The first material in this new class is graphene, a single atomic layer of carbon. This new materialhas a number of unique properties, which makesit interesting for both fundamental studies and future applications.The electronic properties of this 2D-material leads to, for instance, an unusual quantum Hall effect.(2,3)It is a transparentconductor(4) which is one atom thin. It also gives rise to analogies with particle physics, including an exotic type of tunneling(5,6) which was predicted by the Swedish physicist Oscar Klein.(7).In addition graphene has a number of remarkable mechanical and electrical properties.

It is substantially stronger than steel, and it is very stretchable. The thermal and electrical

conductivity is very high and it can be used as a flexible conductor. The Nobel Prize in Physics 2010 honours two scientists, who have made the decisive contributions to this development.

They are Andre K. Geim and Konstantin S. Novoselov, both at the University of Manchester, UK. They have succeeded in producing, isolating, identifying and characterizing graphene.(1,8).

We have come a long way since the first IC chip was invented in 1959 in TI and FairChild simultaneously. The invention of IC Chip has marked the beginning of a new historical era in Man-Kind’s history. This invention has been as crucial as the discovery of fire was or as momentous as the invention of wheel was.

Discovery of Fire brought the proto-human society down from its arboreal abode to its humble cave dwellings. This enabled the development of our society in rapid strides.

On the other hand the invention of wheel led to rapid exchange of ideas and commodities enabling a homogenization across the globe which would have been impossible otherwise.

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
