Kvartsist torusid kasutatakse tavaliselt pooljuhtplaatide k\u00f5rgtemperatuurilistes difusiooniahjudes dopingu (n\u00e4iteks fosfori v\u00f5i boori difusioon) v\u00f5i l\u00f5\u00f5mutamiseks (dopinguainete aktiveerimine).
Kandjate eluiga on peamine parameeter r\u00e4nivaiba kvaliteedi hindamisel. Kui kvartstoru lisandid (n\u00e4iteks metalliioonid) saastavad vahvleid, v\u00f5ib see p\u00f5hjustada kandjate rekombinatsiooni suurenemist ja eluea v\u00e4henemist.

Kvartsist torusid kasutatakse CVD (Chemical Vapor Deposition) reaktsioonikambrites. Kui toru seina saastub v\u00f5i see devitrifitseerub, v\u00f5ib see m\u00f5jutada epitaksikihi kvaliteeti, mille tulemuseks on kandja eluea l\u00fchenemine.<\/p>\n\n\n\n

2. Fotogalvaaniliste (p\u00e4ikesepaneelide) katsetamine<\/h3>\n\n\n\n
K\u00f5rge kasuteguriga p\u00e4ikesepatareide protsessides, nagu PERC ja TOPCon, kasutatakse kvartstorusid passiivkihi (n\u00e4iteks SiNx v\u00f5i Al\u2082O\u2083) sadestamiseks v\u00f5i k\u00f5rgtemperatuurilisel p\u00f5letamisel.
Kandjate eluiga m\u00f5jutab otseselt elemendi muundamise t\u00f5husust. Kui kvartstorusse satub saastet, suureneb vahvli pinnal rekombinatsiooni m\u00e4\u00e4r.
M\u00f5\u00f5tmised viiakse l\u00e4bi QSSPC (Quasi-Steady-State Photoconductance) v\u00f5i \u03bc-PCD (Microwave Photoconductance Decay) abil, et m\u00e4\u00e4rata v\u00e4hemuskandjate eluiga.<\/p>\n\n\n\n
\n\n\n\n3. Materjalide uurimine (nt laia ribal\u00f5hega pooljuhid).<\/h3>\n\n\n\n
R\u00e4nikarbiidi (SiC) v\u00f5i galliumnitriidi (GaN) seadmete k\u00f5rge temperatuuriga protsessid (>1500 \u00b0C) n\u00f5uavad \u00fclipuhtaid kvartstorusid. Lisandid v\u00f5ivad suurendada liidese oleku tihedust, mis toob kaasa kandjate eluea v\u00e4henemise.
Teadusuuringud keskenduvad sageli epitaksiliste kihtide v\u00f5i oksiidikihtide elektrilistele omadustele.<\/p>\n\n\n\n
\n\n\n\n4. Muud seotud testid<\/h3>\n\n\n\n
Kandjate eluiga m\u00f5jutab reageerimiskiirust. Kui kvartstorud saastavad tundlikke materjale (nt InGaAs), v\u00f5ib seadme j\u00f5udlus halveneda.<\/p>\n\n\n\n
M\u00f5ned kliendid v\u00f5ivad lihtsalt kasutada kvartstorusid reaktsioonianumatena, et katsetada uute materjalide (n\u00e4iteks perovksiitide) kandjad\u00fcnaamikat.<\/p>\n\n\n\n

See parameeter on kriitilise t\u00e4htsusega pooljuhtide ja fotogalvaanika valdkonnas, samas kui t\u00fc\u00fcpilistes t\u00f6\u00f6stuslikes v\u00f5i keemilistes katsetes seda tavaliselt spetsiaalselt ei m\u00f5\u00f5deta.<\/p>\n\n\n\n
\u00dcldiste keemiliste katsete puhul on kvartstorude puhtusn\u00f5uded suhteliselt madalad, samas kui pooljuhtide\/fotogalvaanilised protsessid on saastumise suhtes \u00e4\u00e4rmiselt tundlikud.<\/p>","protected":false},"excerpt":{"rendered":"
