Molecular Electronics -Introduction
Molecular electronics is the branch of nanotechnology which deals with the applications and construction of nano building blocks that are used in electronic circuit manufacturing and design. It is sometimes called as moletronics.All the major electronic fabrications are supported by molecular electronics.
The concept of molecular electronics is not new in the field of technology and science.its core concepts were originated with the concept of nano electronics.In 1997 the first ever theory for the molecular electronics was given by by Mark Reed and co-workers.Its one of the important discipline that provides us way for dealing with all the electronic characteristics of conductors,insulators and semi conductors.molecular electronics has two sub disciplines
- molecular materials for electronics
- molecular scale electronics
Both of them collectively give high tech and ultra intelligent devices to be used in various kind of applications.This field is progressing rapidly and supporting nano electronics in order to develop excellent applications.
How Molecular Electronic works?
molecular electronics works at the smallest scale involving single molecules, its characteristics and sub properties.It deals with the substance which are considered to be un explorable in the field of electronics.It also implements all the major laws of electronics in the practical ground basis so that original implementation of theoretical frame work can be seen. Many major components in the field of chemistry, physics, biological science and electronics are the gift of molecular electronics.With the help of this wonderful technology the building blocks of structures can be used in intense and complex fabrications of integrated circuits. It can control the molecular scale properties of individual atom of matter according to the use.he direct measurement of material properties is one of the most vital feature of molecular electronics which cannot be found in any other technology.
Applications of Molecular electronics
Molecular electronics has wide range of applications in the work areas of chemistry, physics, electronics and nano electronics, technology,artificial intelligence and medical equipment. Almost all the fabricated chips in the intelligent machinery that is used on large scale has molecular electronic involved in its construction. For example resistors and transistors that are used in producing electricity,capacitors in space crafts, automation circuits of robots, strategic plant temperature handlers and CT scan for displaying the infected areas of body.
STM and AFM both have molecular electronics involved in their construction.In the field of chemistry it is used to see the chemical reactions in stimulated models of nuclear reactors, and also for measuring the acidic and reactive properties of individual element.
Disadvantages of Molecular Electronic
- Molecular electronics is not at all cost effective.complete fabricated components developed by it are quite expensive and their maintenance cost is also high.
- This technology is not easily understandable.For proper knowledge the basic concepts of nanotechnology and nano electronics must be studied first.
- Difficult error recovery because of high integration at smallest scale, it is hard to detect the physical error in the device.
- The components developed because of high manufacturing cost, its components are not readily available.
- Specialized engineers and scientists are required to handle and control the risks factors of molecular electronics.
Recent progress and future perception
Recent progress can be seen in the shape of experimental and theoretical study of molecular electronics.with the advancement in the nano sciences ,this very concept is stepping up and up to facilitate the world.The most recent foundation of molecular electronics are scanning tunneling microscope and atomic force microscope which has high molecular fabrications and circuits and are also able to measure and control its function accordingly.It can be assumed that in the near future molecular electronics would be flourishing on broader scale and commonly used instruments that are used in many work areas would be having molecular electronic circuits and fabrications in them.
