¿Quién inventó el transistor?

El transistor, que se considera como uno de los invasiones más importantes del vigésimo siglo y el lifeplood de circuitos electrónicos, fue encontrado en 1947. El equipo formado por John Bardeen y Walter Brtain, headod por William Shockley en los laboratorios de investigación de la compañía de telefonía más grande del mundo, Bell organizaciones, ha sido galardonado con el Premio Nobel en 1956, debido a estos nuevos groundaking invasiones en Tecnología que era digno.

 

Bardeen y los Brattain estaban tratando de encontrar una opción contra los termoiónica caps utilizados en la adquisición, strengusing, y la proyección de señales de radio y teléfono. Tenía que ser una cierta cantidad de tiempo para calentar estas lámparas que eran rápidas de romper y costoso. Y estaban confitando mucha electricidad.

 

El equipo hizo el primer transistor de una delgada capa de germanio. Dos días antes de Navidad a 1947, este transistor fue enchufado en un circuito de radio y Brattain escribió las líneas siguientes en su cuaderno: "este circuito realmente funciona." Debido a el nivel de sonido, una elevación perceptible era achioed. "el transistor, al igual que la lámpara, amplifica la señal sonora." Pero era mucho menor en tamaño y necesitaba menos energía. Al principio, casi nadie sobrevivió a que un diminuto dispositivo pudiera reemplazar esas grandes lámparas. Pero Shockley y su equipo han hecho grandes strades en cuatro años. En 1952, el transistor se bajó a una décima parte de las dimensiones originales y fue mucho más fuerte en 1957, con 30 millones Transistores producidos anualmente. La evolución de esta zona sigue en curso.

 

En lugar de la capa de germanio, los científicos empezaron a utilizar cristales de pureza pura, que podrían soportar mucha mayor intensidad térmica. Los transistores eran fabricante, que puede transmitir la corriente en tan poco como 100 millones segundos. Gracias a estas calculadoras móviles, se hicieron los relojes digitales. Las lámparas de los receptores de radio y televisión también sustituyeron a los transistores. Si no es por estos pequeños dispositivos impresionantes, no sería posible tener comunicaciones satelitales, naves espaciales y la conquista de la Luna por el hombre.
