I never got along with my dad. Kids used to come up to me and say, 'My dad can beat up your dad.' I'd say 'Yeah? When?

Junction transistorIn 1951, the invention of the junction transistor was announced by Dr. William Shockley in Murray Hill, N.J. This new type of transistor overcame the problems of the earlier point-contact transistor. The junction transistor was a three-layer sandwich. The outer layers were semiconductors with too many electrons (known as N-type) and the inner layer was the opposite with too few (known as P-type).They weren't up to the point-contact transistor's ability to handle signals that fluctuated extremely rapidly, but in every other way they were superior. The NPN transistors were much more efficient, used very little power to work, and they were so much quieter that they could handle weaker signals than the type-A transistors ever could. |
