MOLETRONICS
[attachment=67492]
INTRODUCTION
Molecular Electronics is recognized as a key candidate to succeed the
silicon based technology once we have arrived at the end of the semi-
conductor roadmap.
Moletronics is a branch of nanotechnology that includes the research
and applications of molecular building blocks for the fabrication of
electronic devices.
Molecular Electronics OR MOLETRONICS
Sometimes called moletronics .
Moletronics can be used to create active components like transistors and passive components like resistors. Here, molecules are considered as switches.
Moletronics is devided in to two sub-disciplines
History Of Molecular Electronics
1956- ARTHUR VON GAVE IDEA ABOUT MOLECULAR ENGINEERING.
The US Air Force laboratory in 1959 came to nothing, because they couldn’t work out how to achieve their goal.
1960s & 1970s- EXPERIMENTS ALL AROUND THE WORLD.
Researchers from Hewlett-Packard and the University of California, Los Angeles, announced in July 1999 that they’ve actually made logic circuits that use molecular level chemical processes.
MOORE’S LAW
Nearly 40 years ago, intel co-founder “GORDON MOORE”
forecasted the rapid pace of technology innovation.
The number of transistors that can be fabricated on a
silicon integrated circuit and therefore the computing
speed of such a circuit is doubling every 18 to 24 months
Size
100X smaller than their counterparts.
Molecules are in the nanometer scale between 1 and 100 nm. This scale permits small devices with more efficient heat dissipation and less overall production cost to be made.
Power
Low power consumption.
Currently Transistors cannot be stacked, which makes them quite ineffecient!
Molecular technology will be able to add a 3rd dimension.
Manufacturing
Most designs use either spin coating or Self-Assembly process.
Individual Molecules can be made exactly the same by the Billions.
Molecular assembly tends to occur at Room Temperature
Applications
Moletronics finds use in a wide range of applications, mainly in the work areas of physics, chemistry, medical equipments, nano electronics and electronics, and artificial intelligence. The construction of almost all fabricated chips used in machinery use the concept of molecular technology.
Sensors.
Displays, Energy transduction devices.
Smart Material, Molecular scale transistors.
Molecular Motors, Logic and memory devices
Future of Molecular Electronics
This technology could be a replacement for VLSI in future.
Controlled fabrication within specified tolerances and its experimental verification are major issues.
Self-assembly schemes based on molecular recognition will be crucial for that task.
Ability to measure electrical properties of organic molecules more accurately and reliably is paramount in future developments.
Conclusion
Even a lot of approach has been proposed in moletronic computer. But there still exists critical problem: most of the technologies are valid only in laboratory condition, and cannot be produced massively.
Today is the age of information explosion. Polymer materials hold hopes of rapid development of improved systems and techniques of computing and communications—the two wings of information technology. For e.g., polymer optical fiber has a number of advantages over glass fibers like better ductivity, light weight, higher flexibility is in splicing and insensitivity to stresses etc.
