    Magawo Aumisiri

    Germanium ngati kristalo wa mono yomwe imagwiritsidwa ntchito kwambiri mu semi-conductor siyowonongeka m'malo a 2μm mpaka 20μm IR. Amagwiritsidwa ntchito pano ngati chinthu chopangira mawonekedwe a IR.
    Germanium ndizolemba zapamwamba zomwe zimagwiritsidwa ntchito popanga ma prism a Attenuated Total Reflection (ATR) a spectroscopy. Chizindikiro chake chotsitsimutsa ndikuti Germanium imapanga zodulira 50% popanda kufunika kokutira. Germanium imagwiritsidwanso ntchito kwambiri ngati gawo lapansi popanga zosefera zamagetsi. Germanium imaphimba gulu lonse la 8-14 micron matenthedwe ndipo imagwiritsidwa ntchito pamakina amagetsi opangira matenthedwe. Germanium imatha kukhala yokutidwa ndi Diamond ndikupanga cholimba cholimba kutsogolo.
    Germanium imabzalidwa pogwiritsa ntchito njira ya Czochralski ndi ochepa opanga ku Belgium, USA, China ndi Russia. Chiwonetsero chazithunzi cha Germanium chimasintha mwachangu ndikutentha ndipo zinthuzo zimakhala zopanda mawonekedwe pamawonekedwe onse pang'ono kuposa 350K pomwe kusiyana kwa gululi kumasefukira ndi ma electron otentha.
    Ntchito:
    • Abwino kwa ntchito pafupi-IR
    • Broadband 3 mpaka 12 μm odana ndi chinyezimiro
    • Zothandiza pazofunsira zomwe zimafuna kupezeka pang'ono
    • Zabwino pazogwiritsa ntchito mphamvu zochepa za CO2 laser
    Mbali:
    • Mawindo a germanium awa sayenda mtunda wa 1.5µm kapena pansipa, chifukwa chake ntchito yake yayikulu imapezeka m'zigawo za IR.
    • Mazenera a Germanium amatha kugwiritsidwa ntchito m'mayeso osiyanasiyana a infrared.
