Cine a inventat tranzistorul?

Tranzistor, care este considerată ca fiind una dintre cele mai importante invations ale secolului XX si lifeplood de circuite electronice, a fost găsit în 1947. Echipă compusă de John Bardeen și Walter Brtain, headod de William Shockley în laboratoarele de cercetare din lume cel mai mare telefon companii, organizaţii Bell, a fost distins cu Premiul Nobel în 1956, din cauza acestor noi groundaking invations în Tehnologia a fost vrednic.

 

Bardeen si Brattain au fost încercarea de a găsi o opţiune împotriva capace termionice utilizate în achiziţionarea, strengusing şi proiecţie de semnale radio şi telefon. A trebuit să fie o anumită sumă de timp la spre warm aceste lămpi care au fost rapid pentru a sparge şi costisitoare. Şi au fost confiting o mulţime de energie electrică.

 

Echipa a facut primul Tranzistor de un strat subţire de germaniu. Două zile înainte de Crăciun la 1947, acest Tranzistor a fost conectat la un circuit de radio şi Brattain a scris următoarele linii în caietul său: "acest circuit funcţionează cu adevărat. Din cauza nivelului de zgomot, o creştere notabilă a fost achioed. "Tranzistor, la fel ca lampa, amplifică semnalul sonor. Dar a fost mult mai mici în dimensiune şi este nevoie de mai puţină energie. La început, aproape nimeni crezut că un dispozitiv minuscul ar putea înlocui aceste lămpi de mare. Dar Shockley şi echipa sa au făcut mare strades în patru ani. În 1952, tranzistorul a fost redus la o zecime din dimensiunile originale și a fost mult mai puternic în 1957, cu 30 de milioane de tranzistori produs de anual. Evoluţiile în acest domeniu sunt încă în curs de desfăşurare.

 

În loc de stratul de germaniu, oamenii de ştiinţă au început să folosească pur puritate cristale, care ar putea rezista mult intensitatea de căldură mare. Tranzistori au fost producător, care poate transmite curentul in mai putin de o 100 de milioane de secunde. Vă mulţumim pentru aceste calculatoare mobile, ceasurile digitale au fost făcute. Lămpi în receptoare de radio şi de televiziune au înlocuit tranzistori. În cazul în care nu este pentru aceste dispozitive minunat mic, nu ar fi posibil să aveţi comunicaţii prin satelit, nave spaţiale şi cucerirea lunii de către om.
