Advanced Facilities Efficient Production Nrov phom: P ntawm gully thiab N, muaj ntau feem ntau thiab cov neeg tsav tsheb tsawg, tam sim no P li feem ntau cov cab kuj tsis muaj dabtsis, thiab N rau hluav taws xob, tsis yog hluav taws xob yog ua kom muaj qhov dav tshuav dynamic, thiab thaum twg txuas mus rau qhov zoo zog mov ntawm txoj kev hloov, thiab thaum kuv teb rov qab rau lub zog, qhov hluav taws xob yuav kov yeej txoj kev hloov tam sim no xaus, tab sis tam sim no ntawm lub teb hluav taws xob hauv qhov rov qab tam sim no yuav kov yeej Lub yeeb nkab yog kev sib tawg.
Cov diav siv lead ua yog pn ib qho ua ke ntawm p-type semiconductor thiab n-type semiconductor, ua ib lub chaw them nqi ntawm ob sab ntawm lub interface, thiab ib lub tebchaw ua tus kheej ua tau. Thaum tsis muaj qhov hluav taws xob sab nraud, qhov hloov tam sim no los ntawm qhov sib txawv ntawm cov cab kuj qhov sib txawv nruab nrab ntawm cov pn hlawv thiab lub tshuab fais fab rau nws tus kheej yog sib npaug zos rau lub xeev hluav taws xob. Thaum sab nraud qhov hluav taws xob offset, qhov sib cuam tshuam ntawm sab nrauv hluav taws xob thiab nws tus kheej ua hluav taws xob ua rau lub zog qis tshaj ntawm cov cab kuj thiab ua rau lub sijhawm tam sim no. Thaum muaj qhov rov ua hluav taws xob sab nraud, sab nraud hluav taws xob thiab nws tus kheej ua hluav taws xob muaj zog ntxiv, thiab qhov rov qab saturation tam sim no I0, uas yog kev ywj siab ntawm qhov rov qab thim qhov siab, yog tsim nyob rau hauv ib co rov qab voltage ntau. Thaum sib txuas nrog rov qab voltage siab txaus, pn hlawv fais fab siv nyob rau hauv qhov chaw them nqi nce mus txog tus nqi tseem ceeb ntawm kev sib txig sib npaug ntawm kev sib txuam, tsim muaj coob tus electron qhov dawm, ua zoo rov qab tam sim no tus nqi, hu ua diode breakdown phenomenon
Muaj ntau ntau hom duab diodes, uas muab faib tau rau hauv German diodes (Ge plawv) thiab silicon diodes (Si tubes) raws li cov ntaub ntawv siv rau semiconductor. Raws li nws txawv USES, nws muaj peev xwm muab faib ua ntsuas lub teeb, kab xij ntoob, kab laug sab, hloov diode, diode cais, diode schitting, lub teeb tawm emitting, thiab lwm yam. Raws li cov qauv tseem ceeb, nws muab faib tau mus rau qhov chaw sib tiv tauj diode, diode hu rau diode thiab planar diode. Diode point-contact diode yog ib txoj hlua khi heev ntawm lub semiconductor wafer uas yog kaj thiab huv, nrog lub plhaub tamsim, kov cov xaim kawg sintering ua ke nrog nti, sib sau ua ke pn. Vim muaj qhov sib cuag, tsuas yog me me xwb (tsis pub ntau tshaj li ob peb lub kaum ntawm milliampere), uas yog tsim rau cov xaim me me tam sim no, xws li xov tooj cua. Qhov "PN Junction" ntawm daim npav ntawm daim npav yog qhov loj thiab pub rau ntau dua tam sim no (ob peb mus rau ob peb lub kaum), uas yog siv los hloov hloov tam sim no mus rau hauv cov cai "tam sim no" rectifier. Planar diode yog ib hom ntawm cov xim silicon tshwj xeeb, uas tuaj yeem tsis dhau txoj kab dav dav, tab sis kuj muaj kev ruaj khov thiab txhim khu kev qha, uas yog siv hauv keyboards, pulses thiab high-frequency circuits.
