Photoconductivity, nce hauv hluav taws xob conductivity ntawm qee yam khoom thaum lawv raug rau lub teeb ntawm lub zog txaus.
Photoconductivity piav qhia yog dab tsi?
Photoconductivity yog qhov tshwm sim kho qhov muag thiab hluav taws xob uas cov khoom siv ua hluav taws xob ntau dua vim qhov nqus ntawm hluav taws xob hluav taws xobxws li pom lub teeb, ultraviolet lub teeb, lub teeb infrared, lossis gamma hluav taws xob.
Photoconductivity xam li cas?
Kev Tshawb Fawb Txoj Kev
- Xaiv ohm txoj cai hauv kev sib cuag hauv qhov tsaus ntuj.
- ntsuas qhov seem conductivity (cov seem lossis tsaus nti tam sim no Io)
- ntsuas lub xeev khov kho photoconductivity rau txhua lub wavelength.
- ntsuas lub teeb teeb liab rau txhua lub wavelength, raug raws li lub ntsuas ntsuas teb (siv txoj cai ntawm peb)
YPhotoconductivity hauv semiconductor yog dab tsi?
Photoconductivity yog qhov nce hauv hluav taws xob conductivity uas tsim los ntawm ci ntsa iab ntawm cov khoom… Qhov tshwm sim tom kawg no tshwj xeeb tshaj tawm hauv cov khoom siv hluav taws xob thaum qhov sib txawv me me thiab lub teeb muaj peev xwm ua kom zoo siab. electrons los ntawm tag nrho valence band mus rau hauv lub khoob khoob khoob khoob khoob.
Cov khoom siv Photoconducting yog dab tsi?
Cov khoom siv yees duab yog siv los tsim cov khoom siv hluav taws xob photoelectric. Cov tshuaj photoconductive muaj xws li germanium, gallium, selenium, lossis silicon nrog impurities, tseem hu ua dopants, ntxiv. Lwm yam khoom siv xws li hlau oxides thiab sulfides.
