A light emitting diode (LED) is an electronic semiconductor component. Current flows through the diode in the forward direction; it emits light, infrared radiation (as infrared light emitting diode) or ultraviolet radiation from a semiconductor material and doping dependent on wavelength.

A LED (Light Emitting Diode) is a new concept in lighting which has incredible energy efficiency, i.e., the amount of energy needed to light is much smaller than even the outbreaks Halogen savers that are known today. (more…)

A multidisciplinary research team at the National Institute of Standards and Technology (NIST), USA, has discovered that an organic semiconductor can be a viable candidate for electronic components such as solar cells and displays that can be applied on a surface spray as easily as paint.

Although these electronic components will not be unique on the market soon, the material studied by the research team could overcome a major cost barriers preventing large-scale manufacture of organic thin film transistors, whose development could lead to a wide variety of components cheap enough to be disposable (throw away).

Silicon is the material more representative of the electronics industry, the largest in the composition of most memory chips and microprocessors. Silicon has been very successful in this industry because it allows them to be herded into a small area of billions of computer components, and is highly sophisticated manufacturing process of these high performance chips.
