Nanoelectronics and Devices

[attachment=55573]

What is Nanoelectronics

Nano electronics refer to the use of nanotechnology on electronic components, especially transistors .
Nanotechnology is generally defined as utilizing technology less than 100 nm in size.
A very small devices to overcome limits on scalability.

Nanofabrication

 single electron transistors, which involve transistor operation based on a single electron.
 Nanofabrication can be used to construct ultradense parallel arrays of nanowires, as an alternative to synthesizing nanowires individually.

Nanomaterials electronics

On 18 October 2011, the European Commission adopted the following definition of a nanomaterial
It studies materials with morphological features on the nanoscale, and especially those that have special properties stemming from their nanoscale dimensions

Molecular electronics

Molecular electronics is the study and application of molecular building blocks for the fabrication of electronic components.
Molecular scale electronics, also called single molecule electronics, is a branch of nanotechnology that uses single molecules, or nanoscale collections of single molecules, as electronic components.

Computers

Nanoelectronics holds the promise of making computer processors more powerful than are possible with conventional semiconductor fabrication techniques.
A number of approaches are currently being researched, including new forms of nanolithography, as well as the use of nanomaterials such asnanowires or small molecules in place of traditional CMOS components.

Memory storage

Electronic memory designs in the past have largely relied on the formation of transistors.
Two leaders in this area are Nantero which has developed a carbon nanotube based crossbar memory called Nano-RAM and Hewlett-Packard which has proposed the use of memristor material as a future replacement of Flash memory.

Novel optoelectronic devices

In the modern communication technology traditional analog electrical devices are increasingly replaced by optical or optoelectronic devices due to their enormous bandwidth and capacity, respectively.
They offer a selectable band gap for the propagation of a certain wavelength, thus they resemble a semiconductor, but for light or photons instead of electrons.

Energy production

 It is believed that the invention of more efficient solar energy would have a great effect on satisfying global energy needs.
There is also research into energy production for devices that would operate in vivo, called bio-nano generators.
A bio-nano generator is a nanoscale electrochemical device, like a fuel cell orgalvanic cell, but drawing power from blood glucose in a living body, much the same as how the body generates energy from food. 

Advantages

One of the obvious advantage is that nanaoelectronics reduces size and scale of the machine with the help of complex integration on the circuit silicon chips.
Advanced propertied of semiconductors can be determined with the help of nanoelectronics.
Extreme fabrication also supported the multiple use of single machine. Parallel processing is also empowered by nanaoelectronics.

Applications

Nanoelectronics have wide range of applications which includes the field of electronics, artificial intelligence, fiction, technology, telecommunications, medical sciences and space exploration.
. Advanced sensors, trackers and detection apparatus are also the inventions of nanoelectronics
 With the help of nano electronics more complex and integrated devices have been created such as nano electronic robots with self replication, bacteria and material purifiers which automatically treat the agent or element according to the boiling points. 

Conclusion

Nanoelectronics is not only about size but also phenomena, mechanism, etc.
Nanoelctronics is a wide open field with vast potential for breakthroughs coming from fundamental research
Some of the major issues that need to be addressed are
Understand nanoscale transport.
Develop/understand self-assembly techniques to do conventional things cheaper.
