Phindu lalikulu la ma capacitor a organometallic film ndilakuti amadzichiritsa okha, zomwe zimapangitsa ma capacitor awa kukhala amodzi mwa ma capacitor omwe akukula mwachangu masiku ano.

Pali njira ziwiri zosiyana zodzichiritsira ma capacitor a filimu yopangidwa ndi zitsulo: imodzi ndi kudzichiritsa yokha; inayo ndi kudzichiritsa yokha pogwiritsa ntchito electrochemical. Yoyamba imachitika pamagetsi okwera, motero imatchedwanso kudzichiritsa kwamphamvu; chifukwa yomalizayi imachitikanso pamagetsi otsika kwambiri, nthawi zambiri imatchedwa kudzichiritsa kwamphamvu pogwiritsa ntchito low-voltage.

Kudzichiritsa Kokha

Kuti tifotokoze momwe zimakhalira kuti kutulutsa madzi kumadzichiritsa, tiyerekeze kuti pali vuto mu filimu yachilengedwe pakati pa ma electrode awiri achitsulo okhala ndi kukana kwa R. Kutengera ndi mtundu wa vutolo, likhoza kukhala vuto lachitsulo, semiconductor kapena vuto losatetezedwa bwino. Mwachionekere, vutolo likakhala limodzi mwa oyamba, capacitor imadzitulutsa yokha pamagetsi otsika. Ndi pomaliza pake pomwe kutulutsa madzi kotchedwa high voltage kumadzichiritsa kokha.

Njira yodzichiritsira yokha ndi yakuti nthawi yomweyo mutatha kugwiritsa ntchito voltage V ku capacitor ya filimu yachitsulo, mphamvu ya ohmic I=V/R imadutsa mu chilemacho. Chifukwa chake, kuchuluka kwa magetsi J=V/Rπr2 kumadutsa mu electrode yachitsulo, mwachitsanzo, malo oyandikira ndi chilemacho (r yaying'ono ndi) ndipo kuchuluka kwa magetsi ake kumakhala mkati mwa electrode yachitsulo. Chifukwa cha kutentha kwa Joule komwe kumachitika chifukwa cha kugwiritsa ntchito mphamvu ya chilema W=(V2/R)r, kukana kwa R kwa semiconductor kapena insulating defect kumachepa kwambiri. Chifukwa chake, mphamvu yamagetsi I ndi W imawonjezeka mwachangu, chifukwa chake, kuchuluka kwa magetsi J1=J=V/πr12 kumakwera kwambiri m'dera lomwe electrode yachitsulo ili pafupi kwambiri ndi chilemacho, ndipo kutentha kwake kwa Joule kumatha kusungunula gawo lachitsulo m'derali, zomwe zimapangitsa kuti arc pakati pa ma electrode awuluke apa. Arc imasanduka nthunzi mwachangu ndikutaya chitsulo chosungunuka, ndikupanga malo otetezedwa opanda chitsulo. Arc imazimitsidwa ndipo kudzichiritsa kumachitika.

Chifukwa cha kutentha kwa Joule ndi arc zomwe zimapangidwa mu njira yodzichiritsira yokha, dielectric yozungulira chilemacho ndi malo osungiramo zinthu zotenthetsera pamwamba pa dielectric amawonongeka mosalephera ndi kuwonongeka kwa kutentha ndi magetsi, motero kuwonongeka kwa mankhwala, mpweya ndi carbonization, komanso kuwonongeka kwa makina kumachitika.

Kuchokera pamwambapa, kuti tipeze njira yabwino yodzichiritsira yokha, ndikofunikira kuonetsetsa kuti pali malo oyenera ozungulira chilemacho, kotero kapangidwe ka capacitor ya organic film yachitsulo kayenera kukonzedwa bwino kuti pakhale njira yoyenera yozungulira chilemacho, makulidwe oyenera a wosanjikiza wachitsulo, malo okhala ndi mpweya wozizira, komanso mphamvu yoyenera yapakati. Chomwe chimatchedwa njira yabwino yodzichiritsira yokha ndi ichi: nthawi yodzichiritsira yokha ndi yochepa kwambiri, mphamvu yodzichiritsira yokha ndi yaying'ono, kupatula bwino zilema, palibe kuwonongeka kwa dielectric yozungulira. Kuti tipeze njira yabwino yodzichiritsira yokha, mamolekyu a filimu yachilengedwe ayenera kukhala ndi chiŵerengero chochepa cha kaboni ndi maatomu a haidrojeni ndi mpweya wochepa, kotero kuti pamene mamolekyu a filimuyo awonongeka mu njira yodzichiritsira yokha, palibe kaboni wopangidwa ndipo palibe mpweya woikidwa kuti tipewe kupangika kwa njira zatsopano zoyendetsera mpweya, koma m'malo mwake CO2, CO, CH4, C2H2 ndi mpweya wina zimapangidwa kuti zimitse arc ndi kukwera kwakukulu kwa mpweya.
Pofuna kuonetsetsa kuti zinthu zozungulira chilemacho siziwonongeka podzichiritsa, mphamvu yodzichiritsa yokha siyenera kukhala yayikulu kwambiri, komanso siikhala yaying'ono kwambiri, kuti ichotse gawo lozungulira chilemacho, kupangidwa kwa malo otetezera kutentha (high resistance), chilemacho chidzalekanitsidwa, kuti chidzichiritse chokha. Mwachionekere, mphamvu yodzichiritsa yokha yofunikira imagwirizana kwambiri ndi chitsulo cha gawo lopangira zitsulo, makulidwe, ndi malo. Chifukwa chake, kuti achepetse mphamvu yodzichiritsa yokha ndikupeza kudzichiritsa bwino, kupangidwa kwa mafilimu achilengedwe okhala ndi zitsulo zochepa zosungunuka kumachitika. Kuphatikiza apo, gawo lopangira zitsulo siliyenera kukhala lolimba komanso lopyapyala, makamaka kupewa kukanda, apo ayi, malo odzipatula a insulation adzakhala ngati nthambi ndipo sadzakwanitsa kudzichiritsa bwino. Ma capacitor a CRE onse amagwiritsa ntchito mafilimu wamba, ndipo nthawi yomweyo amawongolera mosamala kuyang'anira zinthu zomwe zikubwera, kutseka mafilimu olakwika pakhomo, kuti mtundu wa mafilimu a capacitor ukhale wotsimikizika mokwanira.

Kuwonjezera pa kudzichiritsa wekha, palinso ina, yomwe ndi kudzichiritsa wekha pogwiritsa ntchito electrochemical. Tiyeni tikambirane za njira imeneyi m'nkhani yotsatira.
