Ge Crystal

“Ge crystal” yawanci yana nufin kristal da aka yi daga simin germanium (Ge), wanda shine siminconductor abu. Ana amfani da Germanium sau da yawa a fagen infrared optics da photonics saboda keɓaɓɓen kaddarorinsa.

Anan akwai wasu mahimman fannoni na lu'ulu'u na germanium da aikace-aikacen su:

1. Infrared Windows da Lenses: Germanium a bayyane yake a cikin yankin infrared na bakan na'urar lantarki, musamman a cikin tsaka-tsakin igiyar ruwa da kuma dogon zangon infrared. Wannan kadarar ta sa ta dace da kera tagogi da ruwan tabarau da ake amfani da su a cikin tsarin hoto na thermal, kyamarorin infrared, da sauran na'urori masu gani da ke aiki a cikin tsayin raƙuman infrared.
2. Masu ganowa: Har ila yau, ana amfani da Germanium a matsayin wani abu don yin infrared detectors, kamar photodiodes da photoconductor. Waɗannan na'urori na iya juyar da hasken infrared zuwa siginar lantarki, yana ba da damar ganowa da auna hasken infrared.
3. Spectroscopy: Ana amfani da lu'ulu'u na Germanium a cikin kayan aikin infrared spectroscopy. Ana iya amfani da su azaman katako, prisms, da tagogi don sarrafa da kuma nazarin hasken infrared don nazarin sinadarai da kayan aiki.
4. Laser Optics: Ana iya amfani da Germanium azaman kayan aikin gani a cikin wasu infrared lasers, musamman waɗanda ke aiki a tsakiyar kewayon infrared. Ana iya amfani da shi azaman matsakaicin riba ko azaman sashi a cikin cavities na laser.
5. Sarari da Taurari: Ana amfani da lu'ulu'u na Germanium a cikin na'urorin hangen nesa na infrared da kuma wuraren lura da sararin samaniya don nazarin abubuwan sararin samaniya waɗanda ke fitar da hasken infrared. Suna taimaka wa masu bincike tattara bayanai masu mahimmanci game da sararin samaniya wanda ba a iya gani a cikin haske mai gani.

Ana iya shuka lu'ulu'u na Germanium ta hanyar amfani da hanyoyi daban-daban, kamar hanyar Czochralski (CZ) ko Hanyar Tafiya (FZ). Waɗannan matakai sun haɗa da narkewa da ƙarfafa germanium ta hanyar sarrafawa don samar da lu'ulu'u guda ɗaya tare da takamaiman kaddarorin.

Yana da mahimmanci a lura cewa yayin da germanium yana da ƙayyadaddun kaddarorin don infrared optics, amfani da shi yana iyakance ta dalilai kamar farashi, samuwa, da kewayon watsawar sa mai ƙarancin gaske idan aka kwatanta da wasu kayan infrared kamar zinc selenide (ZnSe) ko zinc sulfide (ZnS) . Zaɓin kayan aiki ya dogara da ƙayyadaddun aikace-aikacen da buƙatun tsarin tsarin gani.
