Chi ha inventato il transistor?

Il transistore, che è considerato come uno del invations più importante del ventesimo secolo e del lifeplood dei circuiti elettronici, è stato trovato in 1947. Il team composto da John Bardeen e Walter Brtain, headod da William Shockley nei laboratori di ricerca della più grande compagnia telefonica del mondo, le organizzazioni Bell, è stato insignito del premio Nobel nel 1956, a causa di questi nuovi groundaking invations in Tecnologia che era degno.

 

Bardeen e i Brattain stavano cercando di trovare un'opzione contro i tappi termoionico utilizzati nell'acquisizione, strengusing e proiezione di segnali radio e telefonici. Doveva essere una certa quantità di tempo per scaldare queste lampade che erano veloci per rompere e costoso. Ed erano confiting un sacco di energia elettrica.

 

Il team ha fatto il primo transistor da uno strato di germanio sottile. Due giorni prima di Natale alle 1947, questo transistor è stato inserito in un circuito radio e Brattain ha scritto le seguenti righe nel suo taccuino: "questo circuito funziona davvero. A causa del livello sonoro, un'altezza notevole era achioed. "il transistor, proprio come la lampada, amplificato il segnale acustico. Ma era molto più piccolo di dimensioni e aveva bisogno di meno energia. In un primo momento, quasi nessuno ha vissuto che un piccolo dispositivo potrebbe sostituire quelle grandi lampade. Ma Shockley e il suo team hanno fatto grandi strades in quattro anni. In 1952, il transistore è stato abbassato ad un decimo delle dimensioni originali ed era molto più forte in 1957, con 30 milioni Transistori prodotti annualmente. Gli sviluppi in questo settore sono tuttora in corso.

 

Invece dello strato di germanio, gli scienziati cominciarono ad usare puri cristalli di purezza, che potevano sopportare un'intensità di calore molto maggiore. I transistori erano fornitore, che può trasmettere la corrente in così piccolo quanto 100 milioni secondi. Grazie a queste calcolatrici mobili, sono stati realizzati orologi digitali. Le lampade nei ricevitori radiofonici e della televisione inoltre hanno sostituito i transistori. Se non è per questi dispositivi poco impressionante, non sarebbe possibile avere comunicazioni satellitari, navicella spaziale e la conquista della luna da parte dell'uomo.
