it should be transistor it is a semiconductor device (p-n junction) developed by william shockley dr. jhon bardeen dr brattain

IT IS a device in which one type of extrensic semiconductor is sandwhiched between two layers of other type of semiconductor this causes pn junction with 3 regions P-N-P/N-P-N  known as eimitter ; base ; and collector which is biased by either forward biasing or reverse biasing  emitter has moderate area and heavily doped to provide large no. of carrier to collector for conduction base region is lightly doped doping level of base is inversely proportional to width of base collector has highest area and modretely doped

                                  transistor is specially used for amplification of a signal by using it as a amplifier

Assorted discrete transistors. Packages in order from top to bottom: TO-3, TO-126, TO-92, SOT-23

A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power, the transistor provides amplification of a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Following its release in the early 1950s the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.

The bipolar junction transistor (BJT) was the most commonly used transistor in the 1960s and 70s. Even after MOSFETs became widely available, the BJT remained the transistor of choice for many analog circuits such as simple amplifiers because of their greater linearity and ease of manufacture. Desirable properties of MOSFETs, such as their utility in low-power devices, usually in the CMOS configuration, allowed them to capture nearly all market share for digital circuits; more recently MOSFETs have captured most analog and power applications as well, including modern clocked analog circuits, voltage regulators, amplifiers, power transmitters and motor drivers.
