Transistor/Inventors

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.

What is a transistor in simple words?

A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.

Who is the father of transistor?

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.

How are transistors made?

Transistors are made from silicon, a chemical element found in sand, which does not normally conduct electricity (it doesn’t allow electrons to flow through it easily). Silicon treated this way has fewer of those “free” electrons, so the electrons in nearby materials will tend to flow into it.

What are the names of the three electrodes in a transistor?

There are typically three electrical leads in a transistor, called the emitter, the collector, and the base—or, in modern switching applications, the source, the drain, and the gate.

Why are tubes called valves?

An electron tube, valve, or simply a tube is another name for a vacuum tube. The electric field in the tube accelerates electrons from the cathode to the anode in both thermionic and non-thermionic types. From the above we can conclude that vacuum tubes behave as valves because they can control and amplify the signal.

Who invented diode?

Fleming patented the first true thermionic diode, the Fleming valve, in Britain on November 16, 1904 (followed by U.S. Patent 803,684 in November 1905).

How are BJT created?

BJTs are created by layering p-type and n-type silicon to form a three-layer “sandwich”: The base, to which a small starting current is attached.

What does transistor stand for?

Transistor was an abbreviated combination of the words transconductance (or transfer) and Varistor. Transistor was suggested by John Pierce, a researcher at the lab. The vote was clear–transistor was the name of choice.

Why was the first transistor called a point contact transistor?

Related Questions More Answers Below. When it was announced the name was explained; “because it is a resistor or semiconductor device which can amplify electrical signals as they are transferred through it from input to output terminals.”. This, the very first transistor was called a point-contact transistor.

What are transistors made of?

Parts of a Transistor A typical transistor is composed of three layers of semiconductor materials or more specifically terminals which helps to make a connection to an external circuit and carry the current.

How does a transistor transfer a signal from low resistance to high resistance?

The junction which is forward biased has low resistance path and reversed biased junction has high resistance path. The weak signal which is to be amplified is introduced in low resistance circuit and output is taken from the high resistance circuit. Therefore, a transistor transfers a signal from low resistance to a high resistance.
