TRANZISTORUL BIPOLAR Consideratii teoretice Tranzistorul bipolar a fost realizat in 1947 de John Bardeen, Walter Brattain, iar teoria jonctiunii p-n si a tranzistorului de William Shockley. Cei trei oameni de stiinta au primit premiul Nobel in anul 1956, impreuna cu Walter Houser, pentru contributia lor la fizica semiconductorilor. Numele tranzistorului este realizat prin contopirea cuvintelor " trans fer re zistor Un tranzistor bipolar consta din doua regiuni semiconductoare cu acelasi tip de conductivitate numite emitor si colector , separate de o zona subtire de conductivitate de tip opus numita baza . Criteriile fundamentale pe care trebuie sa le indeplineasca un tranzistor sunt: Emitorul este mult mai puternic dopat decat baza (curentul prin jonctiunea emitorului trebuie sa fie determinat de purtatorii majoritari ai emitorului injectati in baza, injectia de purtatori majoritari ai bazei in emitor trebuie sa fie neglijabila). Regiunea bazei este fizic subtire, mai mica decat lungimea de difuzie (purtatorii injectati in baza o traverseaza fara a suferi procese de recombinare majore). Zona colectorului este fizic mai larga decat cea a emitorului (ajuta la colectarea curentului injectat de emitor si la disiparea eficienta a caldurii generate pe jonctiunea colectorului).

Nézzük tehát a tanszék történetének néhány fontosabb szakaszát! Az elsõ fejezet a tanszék 1949-ben történt alapításával kezdõdik. Alig 3 héttel az év kezdete elõtt fogadta el az ENSZ közgyûlése az Emberi jogok egyetemes nyilatkozatá t, amelynek 19. cikkelye kimondja, hogy „ Mindenkinek joga van a vélemény és kifejezés szabadságához.
