Advanced Facilities Efficient Productionuas muab faib tau rau hauv German diodes (Ge plates) thiab silicon diodes (Si tubes) raws li cov khoom siv hauv semiconductor siv. Raws li nws txawv USES, nws yuav muab faib ua detector diode, rectifier diode, ruaj ntseg diode, hloov diode thiab li ntawm. Raws li cov tub ntxhais cov qauv, nws muab faib tau mus rau kev taw qhia diode, kev hu rau diode thiab diapering 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.
Tus "PN Junction" ntawm daim npav ntawm daim npav yog loj thiab tso cai rau ntau dua tam sim no (ib 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 kev xaiv ntawm cov roj 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 keyboards, pulses thiab high-frequency circuits.
Dia li cas ua hauj lwm.
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 cov nqi fais fab.
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 cov kev tawm tsam 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 txuas nrog qhov rov qab muaj hluav taws xob txaus, qhov 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, tsim kom muaj ntau tus neeg ntawm lub qhov khoob, ua qhov zoo tshaj qhov qub nqi tam sim no, hu ua diode kev ploj zuj zus.
Lub conductivity ntawm ib diode.
Qhov tseem ceeb tshaj plaws ntawm ib qho diode yog kev ua kom muaj kev sib txuas. Hauv Circuit Court, qhov tam sim no tuaj yeem ntws ntawm tus ncej ntawm lub diode, qhov tsis zoo. Cov yam ntxwv ntawm kev voj voog thiab thim rov qab ntawm cov duab raug pom los ntawm kev sim yooj yim.
