Kwihlabathi elintsonkothileyo lokwenziwa kwe-semiconductor, apho ukuguqulwa kwezinto kwenzeka ngokwesikali se-athom, ukufakelwa kwe-ion kuma njengobuchwepheshe belitye lembombo. Le nkqubo, ethi ibhobhoze ngokuchanekileyo ii-wafers ze-silicon ezine-dopant ion ukuze zilungelelanise iipropathi zazo zombane, ixhomekeke kwindawo ebalulekileyo yokuqala: ukuyilwa komqadi we-ion osulungekileyo, ozinzileyo. Embindini womthombo we-ion-injini yale nkqubo inzima{3}}ilele icandelo eliquka ukomelela phantsi kweemeko ezinzima: intambo ye-tungsten.
Enyanisweni, olu cingo lululamileyo, lungummangaliso wenzululwazi yezinto eziphathekayo. Iimeko zokufakelwa kwe-ion zinobutshaba obunoburhalarhume: zidibanisa ubushushu, iikhemistri ezonakalisayo ezivela kwiigesi ezifana ne-BF₃ okanye i-PH₃, kunye nokuqhushumba kwamasuntswana. I-filament, ehlala isebenza njenge-cathode, kufuneka ifudunyezwe kwi-incandescence ukuze ikhuphe ii-electron eziyimfuneko ukuze zivutha kwaye zigcine i-plasma. Ukungaphumeleli apha kukhokelela ekungazinzini kwe-beam, ukungcoliseka kwesinyithi, kunye nexesha lokunciphisa imveliso.
Kutheni le nto i-tungsten ilawula le ndima? Impendulo ilele kwiimpawu zayo ezingenakuthelekiswa nanto:
Ukuchasana nobushushu obugqithisileyo: Ngeyona ndawo iphakamileyo yokunyibilika kwazo zonke iintsimbi (i-3422 degree), i-tungsten filament igcina ingqibelelo yesakhiwo xa abanye beya kusilela.
Ukuxhathisa okuPhezulu kweSputter: Ixhathisa ukukhukuliseka kwi-plasma bombardment, iqinisekisa ubomi obude kunye nemiqadi ye-ion ecocekileyo.
Ukukhutshwa kwe-Electron egqwesileyo: Iimpawu zayo ze-thermionic zilungele ukuvelisa ukuhamba kwe-electron engaguqukiyo efunekayo kwisizukulwana esizinzileyo seplasma, ngakumbi kwimithombo yeCathode engangqalanga (IHC).
Iimfuno -zesizukulwana esilandelayo seetshiphusi, kuquka nezo zesilicon carbide (SiC) kunye ne-gallium nitride (GaN) izixhobo zamandla, zityhala iteknoloji yofakelo ngakumbi. Oku kuqhuba imfuno ethembeke ngakumbi, ephezulu{2}}yezixhobo zomthombo wokusebenza. Umcu we-tungsten uguqukile ukusuka kucingo olulula ukuya kokuchaneka{4}}okusebenzisekayo ngobunjineli, kunye nokuhambela phambili kulawulo lwesakhiwo senkozo kunye ne-doping (umzekelo, ngokunqabileyo{7}}ii-oksidi zomhlaba) eziphucula ukuqina kwayo kunye nokukhupha ukusebenza kakuhle.
Ukufumana olu thunywa{0}}amacandelo abalulekileyo kufuna iqabane elinobugcisa obunzulu besinyithi kunye nokuzinikela ekuchanekeni. Ngaphezulu kweminyaka engamashumi amabini, iZhuzhou Kingdon Industrial & Commercial Co., Ltd (W/Mo Ukusukela ngo-2004) ibe ligama elithembekileyo kwiintsimbi ezixhathisayo. Isebenza ngokukhethekileyo kwiimveliso ze-tungsten kunye ne-molybdenum, i-Kingdon ibonelela ngokuphezulu-ubusulungekileyo, imathiriyeli ethe gqolo eyenziweyo eyimfuneko kwizicelo ezifunwayo njengofakelo lwe-ion.
Iinjineli kunye neengcaphephe zokuthengwa kwempahla ezifuna amacandelo emithombo ye-ion ethembekileyo, kuquka{0}}ukusebenza okuphezulu kwe-tungsten filaments, iZhuzhou Kingdon ibonelela ngobuchule obuqinisekisiweyo kunye nokuveliswa kokugqwesa.
