Ge Crystal

“Ge kristal” na-ezokarị aka na kristal emere site na mmewere germanium (Ge), nke bụ ihe semiconductor. A na-ejikarị Germanium eme ihe n'ọhịa nke infrared optics na photonics n'ihi ihe ndị pụrụ iche ya.

Nke a bụ ụfọdụ isi akụkụ nke kristal germanium na ngwa ha:

1. Windows infrared na lenses: Germanium na-apụta ìhè na mpaghara infrared nke spectrum electromagnetic, karịsịa na etiti ebili mmiri na ogologo infrared. Ngwongwo a na-eme ka ọ dabara maka imepụta windo na lenses eji na sistemu onyonyo ọkụ, igwefoto infrared, na ngwa anya ndị ọzọ na-arụ ọrụ n'ogologo infrared.
2. Ndị nchọpụta: A na-ejikwa Germanium mee ihe dị ka ihe eji eme ihe nchọpụta infrared, dị ka photodiodes na photoconductor. Ihe nchọpụta ndị a nwere ike ịtụgharị radieshon infrared ka ọ bụrụ akara ọkụ eletrik, na-enyere aka ịchọpụta na nha nke ìhè infrared.
3. Spectroscopy: A na-eji kristal Germanium arụ ọrụ na ngwa spectroscopy infrared. Enwere ike iji ha dị ka mkpọsa, prisms, na windo iji megharịa na nyochaa ìhè infrared maka nyocha kemịkalụ na ihe onwunwe.
4. Laser Optics: Enwere ike iji Germanium mee ihe dị ka ngwa anya na ụfọdụ lasers infrared, karịsịa ndị na-arụ ọrụ n'etiti etiti infrared. Enwere ike iji ya dị ka ihe na-enweta uru ma ọ bụ dị ka akụrụngwa na cavities laser.
5. Oghere na mbara igwe: A na-eji kristal Germanium mee ihe na telescopes infrared na ebe ndị na-ahụ maka mbara igwe maka ịmụ ihe ndị dị na mbara igwe na-ebunye radieshon infrared. Ha na-enyere ndị na-eme nchọpụta aka ịnakọta ozi bara uru banyere eluigwe na ala nke a na-adịghị ahụ anya na ìhè a na-ahụ anya.

Enwere ike ịmalite kristal Germanium site na iji ụzọ dị iche iche, dị ka usoro Czochralski (CZ) ma ọ bụ usoro Float Zone (FZ). Usoro ndị a gụnyere ịgbaze na ịgbaze germanium n'ụzọ a na-achịkwa iji mepụta otu kristal nwere ihe ndị akọwapụtara.

Ọ dị mkpa iburu n'obi na ọ bụ ezie na germanium nwere ihe pụrụ iche maka infrared optics, ojiji ya na-ejedebe site na ihe ndị dị ka ọnụ ahịa, nnweta, na nnyefe ya dị warara ma e jiri ya tụnyere ụfọdụ ihe ndị ọzọ infrared dị ka zinc selenide (ZnSe) ma ọ bụ zinc sulfide (ZnS). . Nhọrọ nke ihe na-adabere na ngwa ngwa na ihe achọrọ nke usoro anya.
