Kev Taw Qhia

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