Dab Tsi Yog Diodes

Diodes, tseem hu ua cov diodes siv lead ua, raug xa mus rau diodes. Tsis tas li ntawd, muaj lub tshuab nqus hluav taws xob thaum ntxov; Nws yog cov khoom siv hluav taws xob nrog ib-txoj kev ua tam sim no. Sab hauv lub semiconductor diode muaj PN kev sib tshuam nrog ob lub taub hau. Lub cuab yeej hluav taws xob no muaj qhov tsis zoo tam sim no rau ntawm qhov kev coj ntawm qhov siv hluav taws xob. Feem ntau, cov diode siv lead ua yog pn hlwv tsim los ntawm qhov sintering ntawm p-hom semiconductors thiab n-hom semiconductors. Ib qhov chaw them nqi txheej tsim nyob rau ob sab ntawm qhov kev txuas los tsim hluav taws xob hauv tus kheej. Thaum cov ntawv thov voltage yog sib npaug rau xoom, vim muaj qhov sib txawv hauv kev saib xyuas ntawm cov nqa khoom ntawm ob sab ntawm pn Junction, lub diffusion tam sim no thiab lub txav dej uas tshwm sim los ntawm tus kheej hluav taws xob teb yog qhov sib npaug thiab hauv qhov sib npaug, uas kuj lub diode yam ntxwv nyob rau hauv ib txwm tej yam kev mob.
