physicist William Shockley.
The Shockley diode (named after physicist William Shockley) is a four-layer semiconductor diode, which was one of the first semiconductor devices invented. It is a PNPN diode, with alternating layers of P-type and N-type material.

Who was Dr William Shockley?
William Bradford Shockley Jr.
(February 13, 1910 August 12, 1989) was an American physicist and inventor. He was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain.
What did William Shockley invent?
Wiliam Bradford Shockley (1910-1989) -along with John Bardeen (1908-1991) and Walter Brattain (1902-1987)- was the father of the transistor, the invention that is probably the greatest silent revolution of the twentieth century, which turns 70 in 2017.
Is Shockley diode and Schottky diode same?
Shockley is two PN junction of semiconductors coupled diode where as Schottky diode in metal-semiconductor junction diode. Shockley operates as power, switching device and inorganic solar cell. Schottky diode is operate as signalling and rectifying device.
What was William Shockley famous for?
William Bradford Shockley Jr. was an American physicist and inventor – he managed the research group that invented the point contact transistor. William Bradford Shockley Jr was one of the trio of famous scientists that invented the first transistor.
Did Shockley invent the transistor?
William Shockley headed the team at Bell Telephone Laboratories that studied semiconductors and invented the transistor. The work that he and fellow physicists John Bardeen and Walter Brattain undertook earned them the 1956 Nobel Prize in physics.
Who invented the transistor in 1947?
1947: John Bardeen and Walter Brattain, with support from colleague William Shockley, demonstrate the transistor at Bell Laboratories in Murray Hill, New Jersey. It’s been called the most important invention of the 20th century.
Who discovered semiconductor?
Karl Ferdinand Braun developed the crystal detector, the first semiconductor device, in 1874.
Who invented the first semiconductor?
In 1901, the very first semiconductor device, called “cat whiskers,” was patented. The device was invented by Jagadis Chandra Bose. Cat whiskers was a point-contact semiconductor rectifier used for detecting radio waves. A transistor is a device composed of semiconductor material.
Who invented the transistor?
The three physicists who invented the transistor; William Shockley, John Bardeen, and Walter Brattain were awarded with the Nobel Prize. Considering the inventions that the transistor paved the way for, one could argue that it was the most important invention of the twentieth century.
When was Shockley diode invented?
Shockley diodes were manufactured and marketed by Shockley Semiconductor Laboratory in the late 1950s. The Shockley diode has a negative resistance characteristic.
Who invented Schottky diode?
physicist Walter H. Schottky
The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal.

When was the Schottky diode invented?
In 1938 he created a theory that explained the rectifying behaviour of a metal-semiconductor contact as dependent on a barrier layer at the surface of contact between the two materials. The metal semiconductor diodes later built on the basis of this theory are called Schottky barrier diodes.
Why did Shockley choose Mountainview?
Shockley had become convinced that the natural capabilities of silicon meant it would eventually replace germanium as the primary material for transistor construction.The Shockley Semiconductor Laboratory opened for business in a small commercial lot in nearby Mountain View in 1956.
Who was the father of the transistor and where did he found his company?
John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947. Shockley introduced the improved bipolar junction transistor in 1948, which entered production in the early 1950s and led to the first widespread use of transistors.
Who won a Nobel Peace Prize for the transistor?
John Bardeen
The Nobel Prize in Physics 1956 was awarded jointly to William Bradford Shockley, John Bardeen and Walter Houser Brattain “for their researches on semiconductors and their discovery of the transistor effect.”
Who discovered BJT?
physicist William Shockley
Invented by the physicist William Shockley in 1947, the BJT has gone through a number of iterations over the years.
Who invented transistor in 1948?
In 1948, the point-contact transistor was independently invented by two German physicists working in Paris. (1947 Milestone) Herbert Matar? and Heinrich Welker had been deeply involved in the German radar effort during World War II.
Who invented Mosfet transistor?
. Atalla
Martin (John) M. Atalla. John Atalla is one of the inventors of the metal-oxide-semiconductor field-effect transistor (MOSFET), the most widely employed type of integrated circuit. Born in Port Said, Egypt, Atalla came to the United States for graduate studies at Purdue University.
Who invented the Internet?
Computer scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system referred to as the Internet.
When was the first transistor invented?
December 16, 1947
Without telling Shockley about the changes they were making to the investigation, Bardeen and Brattain worked on. On December 16, 1947, they built the point-contact transistor, made from strips of gold foil on a plastic triangle, pushed down into contact with a slab of germanium.
