Check us out at www.tutorvista.com A semiconductor is a material that has an electrical conductivity between that of a conductor and an insulator, that is, generally in the range 103 siemens per centimeter to 10−8 S/cm. Devices made from semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Semiconductor devices include the various types of transistor, solar cells, many kinds of diodes including the light-emitting diode, the silicon controlled rectifier, and digital and analog integrated circuits. Solar photovoltaic panels are large semiconductor devices that directly convert light energy into electrical energy. An external electrical field may change a semiconductor's resistivity. In a metallic conductor, current is carried by the flow of electrons. In semiconductors, current can be carried either by the flow of electrons or by the flow of positively-charged "holes" in the electron structure of the material. Common semiconducting materials are crystalline solids but amorphous and liquid semiconductors are known, such as mixtures of arsenic, selenium and tellurium in a variety of proportions. They share with better known semiconductors intermediate conductivity and a rapid variation of conductivity with temperature but lack the rigid crystalline structure of conventional semiconductors such as silicon and so are relatively insensitive to impurities and radiation damage. Silicon is used to create <b>...</b>

Silicon Valley is known worldwide as the global center of high tech innovation. In large part, the spark that ignited Silicon Valley's explosive growth can be traced back to a 50 year-old dispute that occurred in the building at 391 San Antonio Road, Mountain View, California. In the 1950s William Shockley was considered a "God" in the electronics world. He led the Bell Labs team that invented the transistor in 1948. With funding from Arnold Beckman -- a wealthy scientist-businessman -- Shockley established the Shockley Semiconductor Laboratory in 1955. Shockley went against Beckman's recommendation to set up in southern California, near Beckman's own company, and established the lab in a former Quonset hut at 391 San Antonio. Shockley's disruptive management style eventually forced eight of his young scientists to approach Arnold Beckman directly in an attempt to remove Shockley from day-to-day management. When their bid fails, the group feels they have burned their bridges and must find alternative employment. Through an East Coast banker, the scientists are introduced to Sherman Fairchild, a New York industrialist. He is intrigued by the potential of silicon transistors and agrees to support the group with an investment of $1.3 million to start a new company called Fairchild Semiconductor. In Silicon Valley lore, the dissenting scientists became known as the Traitorous Eight - some of whom went on to bigger and better things. Bob Noyce and Gordon Moore founded Intel in <b>...</b>

Robert Noyce is credited with Jack Kilby for the invention of the integrated circuit and co-founded both Fairchild Semiconductor and Intel. In this 1984 lecture, Robert Noyce reviews the development of the integrated circuit from its infancy in the 1950s to the early-1980s as well as its impact on technology and society. Noyce discusses the innovations in transistors that lead to the creation of the integrated circuit. Next, Robert Noyce talks about the technical challenges of building increasingly more compact and more powerful semiconductors as well as the overall effects of Moore's Law. Finally, Noyce looks ahead to the future of semiconductor development that was uncertain at the time of this lecture, but is now in our past. Robert N. Noyce was born in Burlington, Iowa and grew up in Grinnell, Iowa. A physics major at Grinnell College, he graduated with a PhD in physics from Massachusetts Institute of Technology in 1953. William Shockley hired him from Philco Corporation to work at Shockley Semiconductor Laboratories in 1956. With eight other employees he left to found Fairchild Semiconductor Corporation in 1957. As general manager of the Fairchild semiconductor operation and a vice president of Fairchild Camera and Instrument, he presided over a decade of innovation in semiconductor technology including co-invention of the integrated circuit. In 1968 Noyce co-founded Intel Corporation with Gordon Moore where he served as President until 1975 when he became Chairman <b>...</b>

Lecture Date: Tuesday, January 24, 2012. One of the greatest challenges humanity faces is finding a way to provide the world's population with clean energy. Since sunlight is our most abundant source of energy, solar cells, which absorb sunlight and create electricity, will become increasingly important over the next several decades. There have been great advances recently using silicon and thin films of semiconductors to make solar cells and solar electricity is just starting to become economically competitive. It is still important, however, to drop the costs further so that it will be possible to utilize even more solar energy. After providing an overview of the solar cell technologies that are currently commercially available, Professor McGehee will describe a relatively new approach that could make it possible to print solar cells in roll-to-roll coating machines similar to those used to make newspapers. Professor McGehee will show how solar cells can be made with organic semiconductors and explain how these cells work. Lecturer: Michael McGehee, Stanford University.

Check us out at www.tutorvista.com Conductors: All conductors share the property that they're able to carry an electric current (a flow of electronic charge) in response to an applied difference in end-to-end voltage. Inside the material it is the electric field (the voltage difference/distance over which it is applied) that forces any free charges to move. In most cases the vast majority of the electrons inside the material are fixed in place — tightly held by the atom they're orbiting. However, in all conductors some of the electrons find a way to move. In some materials the band-gap energy is quite small compared with the average thermal energy available per particle. This means that random thermal motions cause the atoms & electrons to jiggle around, providing some electrons with enough energy to jump the gap. This produces a thermalised population of free electrons in the conduction band and an equal number of freely movable holes in the valance band. These free charge carriers (-ve electrons and +ve holes) can then move in response to an applied field and the material conducts. Some materials have a very small band gap, or even a non-existent gap. Then the conduction and valance bands touch or overlap. This means an electron only requires a tiny amount of extra energy to reach a free energy level. Insulators: The valence band of an insulator is completely full. The electrons in this band are a bit like guests at a very overcrowded party. They cannot move, no matter <b>...</b>
