Ge Crystal

"Ge crystal" feem ntau yog hais txog cov crystal ua los ntawm cov khoom germanium (Ge), uas yog cov khoom siv semiconductor. Germanium feem ntau siv rau hauv kev siv infrared optics thiab photonics vim nws cov yam ntxwv tshwj xeeb.

Nov yog qee qhov tseem ceeb ntawm germanium crystals thiab lawv cov ntawv thov:

1. Cov Qhov Rai Infrared thiab Cov LensGermanium yog pob tshab hauv thaj chaw infrared ntawm lub electromagnetic spectrum, tshwj xeeb tshaj yog nyob rau hauv nruab nrab-yoj thiab ntev-yoj infrared ntau yam. Cov yam ntxwv no ua rau nws tsim nyog rau kev tsim cov qhov rai thiab cov iav siv hauv cov tshuab thermal imaging, cov koob yees duab infrared, thiab lwm yam khoom siv kho qhov muag uas ua haujlwm hauv infrared wavelengths.
2. Cov khoom ntesGermanium kuj tseem siv ua lub hauv paus rau kev ua cov khoom siv infrared detectors, xws li photodiodes thiab photoconductors. Cov khoom siv detectors no tuaj yeem hloov cov hluav taws xob infrared mus ua lub teeb liab hluav taws xob, ua rau muaj peev xwm ntes thiab ntsuas lub teeb infrared.
3. Kev ntsuas qhov muag pomCov khoom siv Germanium siv rau hauv cov cuab yeej infrared spectroscopy. Lawv tuaj yeem siv ua beamsplitters, prisms, thiab qhov rais los tswj thiab tshuaj xyuas lub teeb infrared rau kev tshuaj xyuas tshuaj lom neeg thiab cov khoom siv.
4. Kev Siv Laser OpticsGermanium siv tau ua cov khoom siv kho qhov muag hauv qee lub laser infrared, tshwj xeeb tshaj yog cov uas ua haujlwm hauv nruab nrab infrared. Nws siv tau ua qhov nruab nrab nce lossis ua ib feem hauv cov kab laser.
5. Kev Kawm Txog Qhov Chaw thiab Kev Kawm Txog Hnub QubCov pob zeb Germanium siv rau hauv cov tsom iav infrared thiab cov chaw soj ntsuam hauv qhov chaw rau kev kawm txog cov khoom saum ntuj ceeb tsheej uas tso tawm hluav taws xob infrared. Lawv pab cov kws tshawb fawb sau cov ntaub ntawv tseem ceeb txog lub ntiaj teb uas tsis pom hauv lub teeb pom kev.

Cov siv lead ua los ntawm Germanium tuaj yeem cog tau los ntawm ntau txoj kev, xws li txoj kev Czochralski (CZ) lossis txoj kev Float Zone (FZ). Cov txheej txheem no suav nrog kev yaj thiab khov germanium hauv txoj kev tswj hwm kom tsim cov siv lead ua ib leeg nrog cov yam ntxwv tshwj xeeb.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum germanium muaj cov khoom tshwj xeeb rau infrared optics, nws siv yog txwv los ntawm cov yam xws li tus nqi, muaj, thiab nws qhov sib kis nqaim piv rau qee cov khoom siv infrared xws li zinc selenide (ZnSe) lossis zinc sulfide (ZnS). Kev xaiv cov khoom siv nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau ntawm lub kaw lus kho qhov muag.
