Taw qhia

Lub cev muaj zog ntawm semiconductor PN hlws ris yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm physics thiab electronics.Cov cuab yeej no siv txoj kev sim lub cev los ntsuas qhov kev sib raug zoo ntawm qhov sib txawv ntawm PN kev sib tshuam thiab qhov hluav taws xob, ua pov thawj tias qhov kev sib raug zoo no ua raws li txoj cai kev faib tawm, thiab ntsuas Boltzmann tas li (ib qho tseem ceeb hauv physics) ntau dua, uas ua rau cov tub ntxhais kawm kom kawm ib txoj kev tshiab los ntsuas qhov tsis muaj zog tam sim no.Cov cuab yeej no muab lub tshuab cua sov hloov pauv qhov ntsuas kub ntsuas qhov sib txawv ntawm PN hlws ris voltage thiab thermodynamic kub T, kom tau txais qhov rhiab heev ntawm lub sensor, thiab kwv yees kom tau txais lub zog sib txawv ntawm cov khoom siv silicon ntawm 0K.Cov cuab yeej no ruaj khov thiab txhim khu kev qha, thiab muaj ntau yam kev sim lub cev, lub tswv yim meej, tsim qauv tsim nyog thiab ntsuas qhov tseeb.Cov cuab yeej no tsuas yog siv rau hauv kev sim lub cev dav dav thiab tsim kev tshawb fawb kev sim hauv tsev kawm qib siab thiab tsev kawm qib siab.

Kev sim

1. Qhov kev sib raug zoo ntawm PN junction diffusion tam sim no thiab qhov hluav taws xob junction yog ntsuas, thiab qhov kev sib raug zoo no yuav tsum tau ua pov thawj kom ua raws li txoj cai kev faib tawm exponential los ntawm kev ua cov ntaub ntawv;

2. Boltzmann qhov tsis tu ncua yog ntsuas ntau dua (Qhov yuam kev yuav tsum tsawg dua 2%);

3. Kawm siv lub tshuab ua haujlwm ua haujlwm los tsim lub tshuab hluav taws xob tam sim no los ntsuas qhov tsis muaj zog tam sim no los ntawm 10^-6A rau 10^-8A;

4. Kev sib raug zoo ntawm PN junction voltage thiab kub yog ntsuas thiab rhiab heev ntawm junction voltage nrog kub yog xam;

5. Kwv yees los xam lub zog sib txawv ntawm cov khoom siv semiconductor (silicon) ntawm 0K.
