LEEM-10 Kev Tshawb Nrhiav Kev Ua Yeeb Yam ntawm PN Kev Sib Tw
Cov cwj pwm lub cev ntawm PN kev sib tshuam yog ib qho ntawm cov ncauj lus tseem ceeb hauv kev qhia ntawm physics dav dav, semiconductor physics thiab hluav taws xob. Boltzmann tas mus li yog qhov yooj yim hauv physics. Hauv physics sim qhia cov ntaub ntawv, muaj qee qhov kev ntsuas ntawm qhov pib lub cev ib txwm muaj, xws li cov khoom siv hluav taws xob ntau, cov huab hwm coj kom sib npaug, Planck tas li, thiab lwm yam, tab sis muaj ob peb qhov kev sim rau qhov ntsuas ntawm Boltzmann tas mus li thiab kawm txog Boltzmann qhov faib tawm. PN hlws tes lub zog simter tsim los ntawm peb lub tuam txhab tuaj yeem siv los ntsuas lub zog thiab lub cev Boltzmann tsis tu ncua ntawm PN kev sib tshuam, thiab kawm txoj kev tshiab ntawm kev ntsuas tsis muaj zog tam sim no.
Kev sim
1. Kev ntsuas PN kev sib tw diffusion tam sim no piv rau qhov kev sib tsoo voltage, thiab tau Boltzmann tas li
2. Tsim qhov hloov hluav taws xob tam sim no-siv hluav taws xob siv hluav taws xob ua haujlwm rau kev ntsuas hluav taws xob tsis muaj zog
3. Ntsuas PN hlws ris voltage piv rau qhov kub thiab txias, thiab tau txais cov kev sib nkag siab ntawm cov ntawv hluav taws xob nrog kev ntsuas kub
4. Tau txais kab xev txwv tsis zoo ntawm cov khoom siv silicon ntawm 0 K kwv yees li
5. Ntsuas qhov ntsuas kub thiab hluav taws xob tsis kam siv platinum tsis kam thiab DC tus qauv hlau
