Ki találta fel a tranzisztor?

A tranzisztor, ami tekintik az egyik a huszadik század legfontosabb invations és a lifeplood, elektronikus áramkörök, 1947-ben találták. John Bardeen és Walter Brtain, által William Shockley, a világ legnagyobb telefon társaság, csengő szervezetek kutatási laboratóriumokban headod álló csapat is elnyerte a Nobel-díj 1956-ban, mivel ezek új groundaking invations a Technológia méltó volt.

 

Bardeen és a Brattain voltak kipróbálás-hoz talál egy választás ellen a megszerzése, a strengusing és a vetítés, rádió és telefon jelek Izzókatódos sapkák. Volna, hogy egy bizonyos összeget a idő-hoz meleg ezek a lámpák, hogy gyorsan szünet és költséges. És ők voltak a confiting egy csomó elektromos áram.

 

A csapat az első tranzisztor készült vékony germánium réteg. Az 1947-ben, karácsony előtt két nappal a tranzisztor volt dugva egy rádió áramkör és Brattain a következő sorokat írta a füzetében: "Ez a pálya tényleg működik. Azért, mert a hang egy figyelemre méltó emelés volt achioed. "A tranzisztor, csakúgy, mint a lámpa, fokozza a hangjelzés. De ez sokkal kisebb méretű volt, és kevesebb energia szükséges. Az első, szinte senki sem belived, hogy egy picike berendezés tudna helyettesít azok nagy lámpa. De Shockley és csapata négy év nagy strades tették. 1952-ben, a tranzisztor csökkentették, hogy egytizede az eredeti dimenziókba, és sokkal erősebb volt 1957-ben a 30 millió tranzisztorok által termelt évente. Fejlemények e téren még mindig folyamatban.

 

Germánium réteg helyett tudósok kezdte használni a tiszta tisztasági kristályok, ami sokkal nagyobb hő intenzitású tudott ellenállni. Tranzisztorok, gyártó, amely továbbítja az aktuális mint kicsi mint egy száz millió másodperc volt. Köszönhetően ezek hordozható számológépek digitális órák készültek. A lámpák, a rádió és televízió műsorvevő készülékek is cserélni a tranzisztorok. Ha nem ilyen kis félelmetes eszközök, nem lenne lehetséges, hogy a műholdas, űrhajó és a Hold meghódítása az ember.
