A cikin kayan lantarki na zamani da optoelectronics, kayan semiconductor suna taka rawar da ba za a iya maye gurbinsu ba. Daga wayoyin komai da ruwanka da radar mota zuwa na'urorin masana'antu, na'urorin semiconductor suna ko'ina. Daga cikin dukkan mabuɗin maɓalli, resistivity yana ɗaya daga cikin mahimman ma'auni don fahimta da ƙirƙira aikin na'urar semiconductor.
1. Menene Resistivity?
Resistivity wani adadi ne na jiki wanda ke auna yadda karfi da abu ke adawa da kwararar wutar lantarki, yawanci ana bayyana shi a cikin ohm-centimeters (Ω·cm). Yana nuna "juriya" na ciki wanda electrons ke fuskanta yayin da suke motsawa cikin kayan. Karfe gabaɗaya suna da ƙarancin juriya, masu insulators suna da tsayayya sosai, kuma semiconductor sun faɗi wani wuri a tsakani-tare da ƙarin fa'idar juriya mai jujjuyawa. Resistivity ρ = R * (L / A), inda: R shine juriya na lantarki, A shine yanki na yanki na kayan, L shine tsawon kayan.
2. Abubuwan Da Suke Tasirin Resistivity Semiconductor
Ba kamar karafa ba, ba a gyara juriya na semiconductor ba. Abubuwa masu mahimmanci da yawa sun yi tasiri a kansa:
① Nau'in Abu: Daban-daban semiconductor kayan kamar silicon (Si), gallium arsenide (GaAs), da indium phosphide (InP) da daban-daban na ciki resistivity dabi'u.
② Doping: Gabatar da dopants (irin su boron ko phosphorus) a nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan abubuwa daban-daban suna canza maida hankali mai ɗaukar hoto, yana tasiri sosai ga juriya.
③ Zazzabi: Semiconductor resistivity ya dogara da zafin jiki sosai. Yayin da zafin jiki ya ƙaru, ƙaddamarwar mai ɗauka yana ƙaruwa, gabaɗaya yana haifar da ƙarancin juriya.
④ Tsarin Crystal da Lalacewar: Rashin lahani a cikin tsarin kristal-kamar ɓarna ko lahani-na iya hana motsi mai ɗaukar hoto kuma don haka tasirin tsayayya.
3. Yadda Resistivity ke shafar Ayyukan Na'ura
A aikace-aikace masu amfani, tsayayya kai tsaye yana tasiri ga amfani da wutar lantarki, saurin amsawa, da kwanciyar hankali na aiki. Misali:
A cikin diodes na Laser, matsanancin juriya mai yawa yana haifar da dumama mai mahimmanci, wanda ke shafar ingancin fitowar haske da tsawon rayuwar na'urar.
A cikin na'urorin RF, juriya da aka kula a hankali yana ba da damar daidaitawa mafi dacewa da ingantacciyar sigina.
A cikin masu gano hoto, manyan abubuwan juriya galibi suna da mahimmanci don cimma ƙarancin aikin duhu na yanzu.
Don haka, madaidaicin ƙira da sarrafa juriya suna da mahimmanci a aikin injiniyan na'urar semiconductor.
4. Matsakaicin juriya na masana'antu na yau da kullun (Dabi'un Magana)
Nau'in Material Resistivity (Ω·cm)
Silicon Intrinsic (Si) ~ 2.3 × 10⁵
Doped Silicon (n-type/p-type) 10⁻³ ~ 10²
Gallium Arsenide (GaAs) 10⁶ (Semi-insulating) ~ 10⁻³
Indium Phosphide (InP) 10⁴ ~ 10⁻²
5. Kammalawa
Juriya bai wuce ma'auni kawai ba - muhimmin abu ne wanda ke shafar aiki kai tsaye da amincin na'urorin semiconductor. A Lumispot, muna haɓaka juriya ta hanyar zaɓin kayan aiki, ingantattun dabarun doping, da ingantaccen sarrafa tsari don tabbatar da cewa na'urorinmu suna isar da ingantaccen aiki da kwanciyar hankali a cikin kewayon aikace-aikace.
6. Game da Mu
Lumispot ya ƙware a haɓakawa da kera na'urori masu ƙarfi na semiconductor lasers da na'urorin optoelectronic. Mun fahimci muhimmiyar rawar da sigogin kayan kamar resistivity ke takawa a cikin aikin samfur. Tuntube mu don ƙarin koyo game da kula da tsayayyar ƙima, kayan aikin semiconductor na musamman, da hanyoyin ƙirar laser waɗanda aka keɓance da bukatun aikace-aikacen ku.
