Esikhathini esedlule, incwadi ethi Communications Physics yashicilela isihloko sesayensi esithi "Ukusebenzisa izizinda ze-ferroelectric ukuze uthole amandla angalungile", ababhali bazo okwakuyizazi zefiziksi zaseRussia ezivela eSouthern Federal University (Rostov-on-Don) u-Yuri Tikhonov no-Anna Razumnaya, izazi zefiziksi zaseFrance. Inyuvesi yasePicardy eqanjwe ngoJules Verne Igor Lukyanchuk no-Anais Sen, kanye nososayensi wezinto zokwakha wase-Argonne National Laboratory uValery Vinokur. Lesi sihloko sikhuluma ngokudalwa kwe-capacitor "engenakwenzeka" enecala elibi, elabikezelwa emashumini eminyaka adlule, kodwa manje selisetshenziswe kuphela.
Intuthuko ithembisa uguquko kumasekethe e-elekthronikhi wemishini ye-semiconductor. I-pair of "negative" kanye ne-capacitor evamile ene-charge enhle, exhunywe ochungechungeni, inyusa izinga le-voltage yokufaka endaweni enikeziwe ngaphezu kwenani elilinganiselwe kulokho okudingekayo ekusebenzeni kwezigaba ezithile zamasekhethi kagesi. Ngamanye amazwi, iphrosesa inganikwa amandla amandla kagesi aphansi, kodwa lezo zingxenye zamasekhethi (amabhulokhi) adinga i-voltage eyengeziwe ukuze asebenze azothola amandla alawulwayo nge-voltage eyengeziwe esebenzisa amapheya "negative" kanye nama-capacitor avamile. Lokhu kuthembisa ukuthuthukisa ukusebenza kahle kwamandla kwamasekethe ekhompiyutha nokunye okuningi.
Ngaphambi kwalokhu kuqaliswa kwama-capacitors angalungile, umphumela ofanayo wafinyelelwa isikhathi esifushane futhi ngaphansi kwezimo ezikhethekile kuphela. Ososayensi baseRussia, kanye nozakwabo base-USA naseFrance, baqhamuke nesakhiwo esizinzile nesilula sama-capacitor angalungile, alungele ukukhiqizwa ngobuningi nokusebenza ngaphansi kwezimo ezijwayelekile.
Isakhiwo se-capacitor engalungile esakhiwe izazi ze-physics siqukethe izifunda ezimbili ezihlukene, ngasinye saso esiqukethe ama-nanoparticles e-ferroelectric anenkokhelo ye-polarity efanayo (ezincwadini zaseSoviet zazibizwa ngokuthi i-ferroelectrics). Esimeni sawo esijwayelekile, ama-ferroelectric aneshajili emaphakathi, ebangelwa izizinda eziqondiswe ngokungahleliwe ngaphakathi kokubalulekile. Ososayensi bakwazi ukuhlukanisa ama-nanoparticles ngokushaja okufanayo ezindaweni ezimbili ezihlukene zomzimba ze-capacitor - ngayinye endaweni yayo.
Emngceleni ovamile phakathi kwezifunda ezimbili eziphambene ne-polar, ngokushesha kwavela okuthiwa udonga lwesizinda - indawo yoshintsho lwe-polarity. Kuvele ukuthi udonga lwesizinda lungasuswa uma i-voltage isetshenziswa kwesinye sezifunda zesakhiwo. Ukususwa kodonga lwesizinda endaweni eyodwa kuye kwalingana nokuqoqwa kwenkokhiso engalungile. Ngaphezu kwalokho, lapho i-capacitor ishajwa kakhulu, i-voltage ephansi kumapuleti ayo. Lokhu akunjalo ngama-capacitor avamile. Ukwenyuka kwamandla kuholela ekwandeni kwe-voltage kumapuleti. Njengoba i-capacitor engemihle nevamile ixhunywe ochungechungeni, izinqubo aziphuli umthetho wokongiwa kwamandla, kodwa ziholela ekubukeni kwento ethakazelisayo ngendlela yokwanda kwamandla kagesi ezindaweni ezifunwayo zesekethe ye-elekthronikhi. . Kuzoba mnandi ukubona ukuthi le miphumela izosetshenziswa kanjani kumasekethe kagesi.
