Pn kev sib txuas ua haujlwm tsuas yog hauv forward biased condition.
Yam kev tsis ncaj ncees ntawm P-N kev sib tshuam yog dab tsi?
Nyob. Lub diode (PN hlws ris) nyob rau hauv ib qho hluav taws xob Circuit Court tso cai rau tam sim no ntws yooj yim dua nyob rau hauv ib qho kev taw qhia dua lwm tusForward biasing txhais tau tias muab ib qho hluav taws xob hla lub diode uas tso cai rau tam sim no ntws yooj yim, thaum thim rov qab txhais tau hais tias muab qhov hluav taws xob hla ib lub diode nyob rau hauv qhov opposite direction.
Yuav ua li cas tswj qhov kev coj ua ntawm P-N kev sib tshuam?
Ib qhov siv hluav taws xob nrog qhov taw qhia polarity ntxiv cuam tshuam qhov ntws ntawm electrons hla txoj kev sib tshuam. Rau kev coj ua hauv lub cuab yeej, electrons los ntawm thaj av Nyuav tsum txav mus rau qhov sib txuas thiab ua ke nrog qhov hauv thaj tsam P. Ib qho hluav taws xob rov qab ua rau cov hluav taws xob tawm ntawm kev sib tshuam, tiv thaiv kev ua haujlwm.
Yuav ua li cas yog kev sib tw P-N junction?
Los yog thaum lwm qhov chaw ntawm lub zog siv rau P-N hlws ris nws yog hu ua kev tsis ncaj ncees voltage lossis tsuas yog biasing. Txoj kev no yog nce lossis txo qhov muaj peev xwm ntawm kev sib tshuamVim li ntawd, qhov txo qis ntawm qhov muaj peev xwm ua rau cov neeg nqa khoom tam sim no rov qab mus rau thaj tsam depletion.
Dab tsi yog ob txoj kev sib tw rau kev sib txuas P-N junction diode?
Kev sib tw ntawm p-n junction semiconductor diode
Sab nraud qhov hluav taws xob rau p-n hlws ris diode yog siv nyob rau hauv ib qho ntawm ob txoj kev: rau kev ncaj ncees lossis thim rov qab. Yog hais tias lub p-n hlws ris diode yog rau pem hauv ntej biased, nws tso cai rau cov hluav taws xob tam sim no ntws.
