A p-n sib txuas diode yog ib qho yooj yim semiconductor ntaus ntawv uas tswj cov ndlwg ntawm hluav taws xob tam sim no nyob rau hauv ib tug Circuit Court. Nws muaj qhov zoo (p) sab thiab sab tsis zoo (n) sab. Ua ib p-n sib txuas diode , ib qho txawv impurity ntxiv rau txhua sab ntawm silicon semiconductor los hloov ntau qhov ntxiv los yog electrons tam sim no.

Hais txog qhov no, pn junction sawv rau dab tsi?

Ib p-n kev sib tshuam yog ib tug ciam teb los yog kev sib tshuam ntawm ob hom khoom siv semiconductor, p-type thiab n-type, hauv ib qho siv lead ua ntawm semiconductor. Qhov no tso cai rau hluav taws xob tam sim no dhau los ntawm lub kev sib tshuam tsuas yog nyob rau hauv ib qho kev taw qhia.

Ib yam li ntawd, qhov tsim ntawm pn junction yog dab tsi? Tsim ntawm a P-n junction P-n junctions yog tsim los ntawm kev koom nrog n-hom thiab p-hom semiconductor cov ntaub ntawv, raws li qhia hauv qab no. Txij li cov cheeb tsam n-hom muaj lub siab electron concentration thiab p-hom qhov siab concentration, electrons diffuse los ntawm n-hom rau sab p-hom.

Qhov thib ob, PN kev sib tshuam siv rau dab tsi?

Daim ntawv thov ntawm PN hlws ris Diode Nws kuj tuaj yeem ua tau siv raws li lub hnub ci cell. P-N kev sib tshuam forward bias condition yog siv hauv txhua daim ntawv thov teeb pom kev zoo LED. Voltage nyob rau hauv P-N kev sib tshuam bias yog siv los tsim Temperature Sensors, thiab Reference voltages.

Pn junction Class 12 yog dab tsi?

Chav Kawm 12 Physics Semiconductor Electronics. p-n sib tsim. p-n sib tsim. A p-n sib yog lub hauv paus tsev thaiv ntawm ntau yam khoom siv semiconductor xws li diodes, transistor thiab lwm yam.
