Depletion cheeb tsam los yog depletion txheej yog a cheeb tsam nyob rau hauv ib qho kev sib tshuam P-N diode qhov twg tsis muaj mobile chargers. Depletion txheej ua zoo li lub thaiv uas tawm tsam qhov ntws ntawm electrons los ntawm n-sab thiab qhov ntawm p-sab.
Tom qab ntawd, dab tsi yog qhov depletion txheej hauv pn junction diode?
Nyob rau hauv semiconductor physics, lub cheeb tsam depletion , kuj hu depletion txheej , kev poob qis cheeb tsam, kev sib tshuam cheeb tsam , qhov chaw nqi cheeb tsam los yog qhov chaw them nqi txheej , yog ib qho insulating cheeb tsam nyob rau hauv ib tug conductive, doped semiconductor cov ntaub ntawv uas cov mobile chargers tau diffused tam sim ntawd, los yog raug yuam kom deb ntawm ib tug
Dab tsi yog txhais los ntawm cheeb tsam depletion? n] A cheeb tsam nyob rau hauv ib tug semiconductor ntaus ntawv, feem ntau nyob rau hauv lub juncture ntawm P-hom thiab N-hom ntaub ntawv, nyob rau hauv uas tsis muaj ib tug ntau tshaj ntawm electrons los yog ntawm lub qhov. Loj depletion cheeb tsam inhibit tam sim no ntws. Saib kuj semiconductor diode.
Tsis tas li ntawd, yuav ua li cas depletion txheej yog tsim nyob rau hauv diode?
Thaum P thiab N semiconductors koom ua ke los ua PN junction semiconductor diode , cov hluav taws xob nyob ze ntawm PN kev sib tshuam dhia ntawm N mus rau P thiab qhov ze ntawm qhov kev sib tshuam dhia los ntawm P mus rau N. Qhov tshwm sim no tsim qhov chaw them nqi cheeb tsam los yog a depletion txheej raws li pom hauv daim video.
Dab tsi yog qhov depletion cheeb tsam hauv ib lub diode thiab vim li cas nws tsim?
Depletion Region Paub meej Sau lub qhov ua ib tug tsis zoo ion thiab tawm tom qab ib tug zoo ion ntawm n-sab. Ib qhov chaw them nqi tsim, tsim ib cheeb tsam depletion uas inhibits ib qho kev hloov hluav taws xob ntxiv tshwj tsis yog tias nws tau pab los ntawm kev tso ib qho kev tsis ncaj ncees rau ntawm kev sib tshuam.

Sab saum toj ntawm exosphere cim kab ntawm lub ntiaj teb huab cua thiab interplanetary qhov chaw. Lub exosphere yog txheej txheej sab nraud ntawm lub ntiaj teb huab cua. Nws pib ntawm qhov siab ntawm 500 km thiab tawm mus txog 10,000 km
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Dab tsi yog txheej txheej ntawm prokaryotic cell?
Ntau tus prokaryotes muaj cov nplaum nplaum sab nraud hu ua capsule, uas feem ntau yog ua los ntawm polysaccharides (qab zib polymers). Lub capsule pab prokaryotes cling rau ib leeg thiab rau ntau qhov chaw hauv lawv ib puag ncig, thiab tseem pab tiv thaiv lub cell los ntawm ziab tawm
Cov txheej txheej ntawm lub ntiaj teb yog dab tsi?
Lub ntiaj teb tuaj yeem muab faib ua peb txheej tseem ceeb: lub hauv paus, lub mantle thiab crust. Txhua txheej ntawm cov txheej no tuaj yeem muab faib ua ob ntu: sab hauv thiab sab nraud, sab sauv thiab qis mantle thiab sab av loj thiab dej hiav txwv crust
