LEEM-10 Cov Khoom Siv Sim ntawm PN Junction Cov Yam Ntxwv

Kev sim

1. Ntawm tib qhov kub, ntsuas cov yam ntxwv ntawm volt-ampere pem hauv ntej ntawm PN junction thiab xam Boltzmann tas li;

2. Lub zog tam sim no kuv tseem tsis hloov pauv, qhov nkhaus VT ntawm qhov hluav taws xob pem hauv ntej ntawm qhov sib tshuam PN raug mapped, qhov rhiab heev raug suav, thiab qhov dav ntawm qhov sib txawv ntawm cov khoom siv PN sib tshuam ntsuas tau kwv yees;

3. Kev sim ua daim ntawv thov: siv ib qho PN junction los ntsuas qhov kub tsis paub;

4. Kev sim tshiab: Raws li cov ntaub ntawv sim, kwv yees qhov rov qab tam sim no Is ntawm PN junction.

5. Kev sim tshawb nrhiav: Saib xyuas qhov cuam tshuam ntawm qhov loj ntawm cov hluav taws xob sib xyaw.

Cov txheej txheem tseem ceeb

1. Ntau yam PN sib txuas nrog cov ntim khoom, suav nrog cov raj silicon, cov raj germanium, NPN transistors, thiab lwm yam.;

2. Qhov tso zis tam sim no yog 10nA ~ 1mA, kho tau hauv 4 ntu, kho kom zoo: yam tsawg kawg nkaus 1nA, tsav tsheb voltage

Txog li 5V, hla cov lus ≤ 1 lo lus/feeb;

3. Lub ntsuas hluav taws xob digital voltmeter uas muaj qhov tsis kam siab heev 4-1/2 tus lej, ob theem ntawm qhov tsis kam sab hauv: 10MΩ, qib tsis kam siab heev (ntau dua 1GΩ), ntau yam ntsuas: 0 ~ 2V, kev daws teeb meem: 0.1mV; kev tsis paub tseeb ntawm kev ntsuas: 0.1% ± 2 lo lus.

4. Kub sim: chav sov ~ 99 ℃, tus pas ntsuas kub digital: 0 ~ 100 ℃, kev daws teeb meem 0.1 ℃;

5. Xws li lub tshuab cua sov hluav taws xob, lub raj mis Dewar thiab lub khob iav.
