I-InSb wafer engu-2 intshi engu-3 intshi engavulwanga uhlobo lwe-Ntype P 111 100 yama-Infrared Detectors

Incazelo emfushane:

Ama-wafer e-Indium Antimonide (InSb) ayizinto ezibalulekile ezisetshenziswa kubuchwepheshe bokuthola i-infrared ngenxa ye-bandgap yawo encane kanye nokuhamba okuphezulu kwama-electron. Atholakala ngobubanzi obungu-2-intshi no-3-intshi, lawa ma-wafer atholakala ngokuhlukahluka okungavulwanga, uhlobo lwe-N, kanye nohlobo lwe-P. Ama-wafer enziwe ngokuqondiswa okungu-100 no-111, okunikeza ukuguquguquka kokusetshenziswa okuhlukahlukene kwe-infrared kanye nezinhlelo zokusebenza ze-semiconductor. Ukuzwela okuphezulu nomsindo ophansi wama-wafer e-InSb kuwenza afaneleke ukusetshenziswa kuma-detector e-infrared (MWIR) aphakathi nendawo, izinhlelo zokuthwebula izithombe ze-infrared, kanye nezinye izinhlelo zokusebenza ze-optoelectronic ezidinga ukunemba kanye namakhono okusebenza okuphezulu.

Ukulungele i-Epi:
1. Lawa ma-wafer alungele i-epi, okwenza afaneleke ukusetshenziswa okubandakanya ukukhula kwe-epitaxial lapho izendlalelo ezengeziwe zezinto zizobekwa khona ku-wafer ukuze kwenziwe idivayisi ye-semiconductor noma ye-optoelectronic ethuthukisiwe.

Izicelo

1. Izitholi ze-Infrared:Ama-wafer e-InSb asetshenziswa kabanzi ekwakhiweni kwezitholi ze-infrared, ikakhulukazi ezindaweni eziphakathi nendawo ze-infrared (MWIR). Abalulekile ezinhlelweni zokubona ebusuku, ekuthathweni kwezithombe ezishisayo, kanye nasekusetshenzisweni kwezempi.
2. Izinhlelo Zokuthwebula Izithombe Ze-Infrared:Ukuzwela okuphezulu kwama-wafer e-InSb kuvumela ukuthwebula izithombe ze-infrared okunembile emikhakheni eyahlukene, okuhlanganisa ezokuphepha, ukuqapha, kanye nocwaningo lwesayensi.
3. Ama-elekthronikhi Asheshayo:Ngenxa yokuhamba kwawo okuphezulu kwama-electron, lawa ma-wafer asetshenziswa kumadivayisi e-elekthronikhi athuthukile njengama-transistors anesivinini esikhulu namadivayisi e-optoelectronic.
4. Amadivayisi Omthombo We-Quantum:Ama-wafer e-InSb alungele ukusetshenziswa kwe-quantum well kuma-laser, kuma-detector, nakwezinye izinhlelo ze-optoelectronic.
