  1. WHAT ARE SEMICONDUCTORS?

  2. Semiconductors are defined as materials that have a connectivity between nonconductors and conductors, according to the Department of Materials Science and Engineering at the University of Illinois Urbana-Champaign. Nonconductors are generally classified as ceramics, while conductors are generally classified as metals. Semiconductors can be a variety of elements. For instance, semiconductors can be pure elements such as germanium or silicon, or they can be compounds such as cadmium selenide or gallium arsenide.

  3. Importance in Daily Life Semiconductors are an important part of your everyday life in 2011, reports the Department of Materials Science and Engineering at the University of Illinois Urbana-Champaign, because they are used in the creation of common electronic devices. Semiconductors are a part of TVs, efficient medical diagnostic equipment, video games, computers and radios. While some of these electronic devices could still be made with vacuum-tube technology, they would not be as reliable, compact or fast. Without the presence of semiconductors in common electronic devices, your life would be harder.

  4. Uses Semiconductors are used in a host of products, notes HistoryKing.com. Silicon is the most widely used substance in semiconductors; it is used in diodes and transistors. Circuit boards, computer components, strain gages, radiation detectors and photo sensors also use silicon semiconductors. There are both elemental as well as compound semiconductors in the marketplace. Silicon semiconductors are elemental semiconductors. Compound semiconductors are used in gadgets such as LED screens, where there inclusion allows the display of a multitude of colors, which elemental semiconductors are not capable of creating.

  5. History The history of semiconductors can be traced back to 1833, the year in which Michael Faraday realized that electrical resistance goes down as the temperature increases in silver sulfide. This has been called the first investigation of a semiconductor. Fast-forwarding to 1947, Schockley, Brattain and Bardeen came up with the transistor, which gave birth to the semiconductor electronics industry, asserts the Department of Materials Science and Engineering at the University of Illinois Urbana-Champaign. The most recent, significant event in the industry occurred in 1993, when the gallium nitride light emitting diode was made.

  6. Future The future of the semiconductor is one that includes a lot of potential, indicates the Department of Materials Science and Engineering at the University of Illinois Urbana-Champaign. The field of telecommunications is one area where semiconductors are being applied. The Internet needs technology that makes it possible to receive and deliver information at fast rates of speed. Optoelectronics is one area where semiconductors are already being applied. Much of the information sent over long distances uses light pulses sent through fiber optic cables. Semiconductors that detect these pulses are a heavily focused area of research in 2011.
