Shockley derives an equation for the voltage across a p-n junction in a long article published in 1949. [2] Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3]
The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).
William Bradford Shockley Jr. (February 13, 1910 – August 12, 1989) was an American inventor, physicist, and eugenicist.He was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain.
From the Shockley ideal diode equation given above, it might appear that the voltage has a positive temperature coefficient (at a constant current), but usually the variation of the reverse saturation current term is more significant than the variation in the thermal voltage term.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell , and give guidance on the phenomena that contribute to losses and ...
First edition. Electrons and Holes in Semiconductors with Applications to Transistor Electronics is a book by Nobel Prize winner William Shockley, [1] first published in 1950. . It was a primary source, and was used as the first textbook, for scientists and engineers learning the new field of semiconductors as applied to the development of the transis

The Shockley–Ramo theorem is a method for calculating the electric current induced by a charge moving in the vicinity of an electrode.Previously named simply the "Ramo Theorem", the modified name was introduced by D.S. McGregor et al. in 1998 [1] to recognize the contributions of both Shockley and Ramo to understanding the influence of mobile charges in a radiation detector.
