A Schottky diode yog ib hom khoom siv hluav taws xob, uas tseem hu ua kev thaiv diode . Nws yog dav siv nyob rau hauv ntau daim ntawv thov xws li ib tug tov khoom, nyob rau hauv radiofrequency daim ntaub ntawv, thiab raws li ib tug rectifier nyob rau hauv lub hwj chim daim ntaub ntawv. Nws yog ib tug tsawg voltage. diode . Lub zog poob qis dua piv rau PN kev sib tshuam diodes.
Ib yam li ntawd, nws tau nug, qhov txawv ntawm Schottky diode thiab ib txwm diode yog dab tsi?
Raws li nyob rau hauv Schottky diode kev sib tshuam yog nyob rau hauv nruab nrab N hom semiconductor rau hlau phaj. Cov scottky thaiv diode muaj electrons raws li feem ntau muaj nyob rau ntawm ob sab ntawm txoj kev sib tshuam. Yog li nws yog ib qho khoom siv unipolar. Ib lo lus rau pem hauv ntej voltage poob (Vf) yog tsawg dua piv rau ib txwm PN kev sib tshuam hom diodes.
Tsis tas li ntawd, dab tsi yog diode thiab nws siv rau dab tsi? Diodes tuaj yeem yog siv Raws li rectifiers, signallimiters, voltage regulators, switches, signal modulators, signalmixers, signal demodulators, thiab oscillators. Fundamentalproperty ntawm a diode yog nws nyiam ua hluav taws xob hauv ib qho kev taw qhia xwb.
Ntxiv mus, Schottky barrier diode ua haujlwm li cas?
Vim li no, electrons tsis tuaj yeem ntws hla lub Schottky Barrier . Nyob rau hauv pem hauv ntej txoj kev tsis ncaj ncees lawm, anelectron tam sim no nyob rau hauv N-sab tau txais ntau lub zog los hla lub junction thaiv thiab nkag mus rau hauv cov hlau. Vim li no, theelectrons kuj hu ua cov cab kuj kub. Vim li no, diode hu ua hot carrier Diode.
Vim li cas Schottky diode hu ua kub cab kuj diode?
Schottky Barrier ( Kub - Tus neeg nqa khoom ) Diodes . A Schottky diode , kuj paub as a kub cab kuj diode , yog ib tug semiconductor diode uas muaj qhov qis qis rau pem hauv ntej voltage poob thiab hloov pauv sai heev. Muaj ib qho me me voltage poob thoob plaws diode terminals thaum tam sim no ntws los ntawm a diode.

Lub hom phiaj ntawm ntau lub hom phiaj Internet mail extensions mime yog dab tsi?
Multipurpose Internet Mail Extension (MIME) raws tu qauv. MIME yog ib hom kev ntxiv lossis cov txheej txheem ntxiv uas tso cai rau cov ntaub ntawv tsis yog ASCII xa mus rau SMTP. Nws tso cai rau cov neeg siv sib pauv ntau hom ntaub ntawv hauv Is Taws Nem: suab, yees duab, duab, daim ntawv thov kev pab cuam thiab
Lub hom phiaj ntawm jumper ntawm lub hard drive yog dab tsi?
Jumpers yog siv los teeb tsa cov chaw rau lub computer peripherals, xws li cov motherboard, hard drives, modems, suab phaib, thiab lwm yam khoom. Piv txwv li, yog tias koj lub motherboard txhawb kev nkag mus rau kev nkag mus, lub jumper tuaj yeem ua rau muaj kev cuam tshuam los yog lov tes taw cov yam ntxwv no
