Silicon bụ kristal mono nke a na-ejikarị eme ihe na ọkara-eduzi na ọ naghị amị mkpụrụ na mpaghara 1.2μm ruo 6μm IR.A na-eji ya ebe a dị ka ngwa anya maka ngwa mpaghara IR.
A na-eji silicon dị ka windo anya nke ọma na band 3 ruo 5 micron yana dị ka mkpụrụ maka mmepụta ihe nzacha anya.A na-ejikwa nnukwu blọk nke Silicon nwere ihu na-egbu maramara dị ka ebumnuche neutron na nnwale physics.
Silicon na-eto site na Czochralski pulling techniques (CZ) ma nwee ụfọdụ oxygen nke na-ebute eriri absorption na 9 microns.Iji zere nke a, enwere ike ịkwado Silicon site na usoro Float-Zone (FZ).Silicon Optical na-adịkarị obere doped (5 ruo 40 ohm cm) maka nnyefe kacha mma karịa 10 microns.Silicon nwere ihe ngafe ọzọ 30 ruo 100 microns nke na-arụ ọrụ naanị na ihe anaghị akwụ ụgwọ dị elu.Doping na-abụkarị boron (p-ụdị) na phosphorus (n-ụdị).
Ngwa:
• Kwesịrị ekwesị maka ngwa NIR 1.2 ruo 7 μm
• Broadband 3 ruo 12 μm mgbochi ntụgharị uche
• Kwesịrị ekwesị maka ngwa nwere mmetụta dị arọ
Njirimara:
• Window silicon ndị a anaghị ebufe na mpaghara 1µm ma ọ bụ n'okpuru, yabụ ngwa ngwa ya dị na mpaghara IR.
• N'ihi na ọ dị elu thermal conductivity, ọ dị mma maka iji dị ka enyo laser dị elu
▶ Window silicon nwere elu igwe na-egbuke egbuke;ọ na-egosipụta ma na-amịkọrọ mana ọ naghị ebufe na mpaghara a na-ahụ anya.
▶ Silicon windows nlegharị anya elu na-ebute mfu nnyefe nke 53%.(ntụgharị uche dị elu data 1 na 27%)
