POINT CONTACT TRANSISTOR

The three famous Scientist namely " JHON BARDEEN, BRATTAIN WALTER, WILLIAM SCHOKLY " revolutionized the feild of elctronics by inventing the TRANSISTOR.


The transistor is on the list of IEEE milestones in electronics, and the inventors were jointly awarded the 1956 Nobel prize in physics for their achievement.

"Signal is transfered through different resistance under system control signal is called TRANSISTOR" .

The first ever transistor is a POINT CONTACT TRANSISTOR i.e invented in bell labs


Today we have BJT(bipolar junction transistor), FET(field effect transistor), MOSFET(metal oxide field effect transistor), IGBT(insulated gate bipolar transistor) , all these are possible because of above three mention scientist.
