When was the first transistor created?
1947 at Bell Labs. It was a germanium point contact transistor.
What transistor is practically obsolete and has been replaced by the junction transistor?
triode ....is not the answer point contact is the answer
Which came first the diffused junction transistor the point contact transistor the surface barrier transistor or the alloy junction transistor?
The point-contact was the first device marketed, following Bardeen and Brattain's patent in 1948, and parallel work by Welker and Matare in France.The Nobel Prize was awarded to Bardeen, Brattain and Shockley - although Shockley had not been a major part of the point-contact work.The junction transistor *principle* was patented by Julius Lilienfeld in 1928.Shockley patented the junction transistor in 1948, soon after Bardeen and Brattain.
Where did the first transistor computer come from?
bell labs built one out of early point contact transistors in 1948 before the invention of the junction transistor.
Who created the transistor?
William Shockley created the transistor.
What types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
When was Transistor Revolt created?
Transistor Revolt was created in 2000.
What transistor is used most in computer circuits?
at this time it is metal oxide field effect transistor. 20 years ago it was mostly bipolar junction transistor, 45 years ago it was point contact or surface barrier transistor. before that it was vacuum tubes and germanium point contact diodes. in the future it may be nanotube field effect transistors, or even DNA logic. both would probably be operating in a thin film of some liquid which would have to be encapsulated.
On what basis the third terminal of a transistor is given name base?
In the original point contact transistor design, there was a base of semiconductor material at the bottom to which two point contact wires were connected, each point contact wire being very close to the other on the surface of the base. There were three wires, one to each of the point contacts and one to the semiconductor base. The two point contacts were called the collector and emitter, and the base was called - logically, being at the bottom - the base.We tend to show the base as being between the collector and emitter, but in actuality the collector and emitter were added on top of the base.Although all modern bipolar transistors are junction transistors, the standard bipolar transistor symbol is actually a point contact transistor symbol, although the base may be drawn on any side not just the bottom.
When was Magic Transistor Radio created?
Magic Transistor Radio was created in 1973.
When was Twisted Transistor created?
Twisted Transistor was created on 2005-09-27.
