Kalekale, buku la Communications Physics linasindikiza nkhani ya sayansi "Kugwiritsa ntchito madera a ferroelectric kuti athe kulepheretsa mphamvu," olemba omwe anali akatswiri a sayansi ya zakuthambo aku Russia ochokera ku Southern Federal University (Rostov-on-Don) Yuri Tikhonov ndi Anna Razumnaya, akatswiri a sayansi ya zakuthambo ochokera ku French. Yunivesite ya Picardy yotchedwa Jules Verne Igor Lukyanchuk ndi Anais Sen, komanso wasayansi wa zipangizo kuchokera ku Argonne National Laboratory Valery Vinokur. Nkhaniyi ikukamba za kulengedwa kwa "chosatheka" capacitor ndi chiwongoladzanja choipa, chomwe chinanenedweratu zaka zambiri zapitazo, koma tsopano chakhala chikugwiritsidwa ntchito.
Chitukukochi chikulonjeza kusintha kwamagetsi amagetsi a zida za semiconductor. A awiri a "negative" ndi ochiritsira capacitor ndi malipiro zabwino, olumikizidwa mu mndandanda, kumawonjezera athandizira voteji mlingo pa mfundo anapatsidwa pamwamba pa mtengo mwadzina kuti chofunika ntchito zigawo zapadera za madera amagetsi. Mwa kuyankhula kwina, purosesa ikhoza kuyendetsedwa ndi magetsi otsika kwambiri, koma zigawozo za mabwalo (midadada) zomwe zimafuna mphamvu yowonjezera kuti zigwire ntchito zidzalandira mphamvu zoyendetsedwa ndi magetsi owonjezereka pogwiritsa ntchito ma "negative" ndi ma capacitors ochiritsira. Izi zikulonjeza kupititsa patsogolo mphamvu zamagetsi zamagetsi zamakompyuta ndi zina zambiri.
Izi zisanachitike kukhazikitsidwa kwa ma capacitors oyipa, zotsatira zofananira zidakwaniritsidwa kwakanthawi kochepa komanso pamikhalidwe yapadera. Asayansi aku Russia, pamodzi ndi anzawo ochokera ku USA ndi France, abwera ndi dongosolo lokhazikika komanso losavuta la ma capacitor olakwika, oyenera kupanga misa komanso kugwira ntchito moyenera.
Mapangidwe a capacitor olakwika opangidwa ndi akatswiri a sayansi ya zakuthambo ali ndi zigawo ziwiri zolekanitsa, zomwe zili ndi ferroelectric nanoparticles ndi malipiro a polarity omwewo (m'mabuku a Soviet ankatchedwa ferroelectrics). Munthawi yake yabwino, ma ferroelectrics amakhala ndi mtengo wosalowerera ndale, womwe umachitika chifukwa cha madera okhazikika mkati mwazinthuzo. Asayansi adatha kulekanitsa nanoparticles ndi malipiro omwewo m'madera awiri osiyana a capacitor - aliyense m'dera lake.
Pamalire wamba pakati pa zigawo ziwiri zotsutsana ndi polar, chotchedwa khoma la domain nthawi yomweyo chinawonekera - malo akusintha kwa polarity. Zinapezeka kuti khoma la domain lingasunthidwe ngati voteji ikugwiritsidwa ntchito kuchigawo chimodzi cha kapangidwe kake. Kusamutsidwa kwa khoma lakumalo kunjira imodzi kunakhala kofanana ndi kudzikundikira kwa mlandu woyipa. Kuphatikiza apo, pomwe capacitor imayimbidwa, kutsika kwamagetsi pama mbale ake. Izi sizili choncho ndi ma capacitors ochiritsira. Kuwonjezeka kwa mphamvu kumabweretsa kuwonjezeka kwa magetsi pa mbale. Popeza capacitor zoipa ndi wamba olumikizidwa mu mndandanda, njira sizimaphwanya lamulo la kusunga mphamvu, koma kumabweretsa maonekedwe a chodabwitsa chodabwitsa mu mawonekedwe a kuwonjezeka kwa magetsi magetsi pa mfundo zofunika dera lamagetsi. . Zidzakhala zosangalatsa kuona momwe zotsatirazi zidzagwiritsidwire ntchito muzitsulo zamagetsi.
