Imwe nguva yapfuura, bhuku reCommunication Fizikisi rakaburitsa chinyorwa chesainzi "Kubatanidza ferroelectric domains for negative capacitance", vanyori vacho vaive maRussian physics kubva kuSouthern Federal University (Rostov-on-Don) Yuri Tikhonov naAnna Razumnaya, nyanzvi dzefizikisi kubva kuFrench. Yunivhesiti yePicardy yakatumidzwa zita raJules Verne Igor Lukyanchuk naAnais Sen, pamwe nesainzi wemidziyo kubva kuArgonne National Laboratory Valery Vinokur. Nyaya yacho inotaura nezvekusikwa kwe "zvisingabviri" capacitor ine mhosva yakaipa, iyo yakafanotaurwa makumi emakore apfuura, asi ikozvino yave ichishandiswa.
Iyo budiriro inovimbisa shanduko mumaseketi emagetsi emidziyo yesemiconductor. Peya ye "negative" uye yakajairwa capacitor ine chaji yakanaka, yakabatana munhevedzano, inowedzera iyo yekupinza voltage level pane yakapihwa nzvimbo pamusoro pezita rekukosha kune inodiwa pakushanda kwezvikamu zvakananga zvemaseketi emagetsi. Mune mamwe mazwi, processor inogona kufambiswa nemhepo yakaderera, asi izvo zvikamu zvemaseketi (mabhuroki) anoda kuwedzera voltage kuti ashande achagamuchira simba rinodzorwa nekuwedzera voltage uchishandisa mapeya e "negative" uye akajairwa capacitors. Izvi zvinovimbisa kuvandudza simba resimba remakomputa maseketi nezvimwe zvakawanda.
Pamberi pekuitwa uku kweasina capacitor, mhedzisiro yakafanana yakawanikwa kwenguva pfupi uye chete pasi pemamiriro akakosha. Masayendisiti eRussia, pamwe chete nevamwe vanobva kuU.SA neFrance, vauya neyakagadzika uye yakapusa chimiro cheyakaipa capacitors, yakakodzera kugadzirwa kwemazhinji uye kushanda pasi pemamiriro akajairwa.
Chimiro chechakaipa capacitor chakagadzirwa nevefizikiki chine nzvimbo mbiri dzakaparadzana, imwe neimwe ine ferroelectric nanoparticles ine mutero weiyo polarity (mumabhuku eSoviet vainzi ferroelectrics). Mumamiriro avo emazuva ese, maferroelectrics ane charger isina kwayakarerekera, iyo inokonzerwa nemadomasi akatarisana mukati mezvinhu. Masayendisiti akakwanisa kuparadzanisa nanoparticles nechaji imwechete munzvimbo mbiri dzakasiyana dzemuviri we capacitor - imwe neimwe munzvimbo yayo.
Pamuganho wakajairika pakati penzvimbo mbiri dzakapesana dzepolar, inonzi domain wall yakabva yaoneka - nzvimbo yekuchinja kwepolarity. Zvakazoitika kuti durawall rinogona kutamiswa kana voltage ikaiswa kune imwe yematunhu eiyo chimiro. Kutamiswa kwedurawall mune imwe nzira kwakave kwakaenzana nekuunganidzwa kwechaji yakaipa. Uyezve, iyo yakawanda iyo capacitor inochajwa, iyo inodzika iyo voltage pamahwendefa ayo. Izvi hazvisizvo nezvezvakajairwa capacitors. Kuwedzera kwemutero kunotungamirira kukuwedzera kwemagetsi pamahwendefa. Sezvo iyo yakaipa uye yakajairwa capacitor yakabatana munhevedzano, maitiro haatyore mutemo wekuchengetedza simba, asi anotungamira pakuonekwa kwechinhu chinonakidza muchimiro chekuwedzera kwemagetsi ekupa panzvimbo dzinodiwa mumagetsi edunhu. . Zvichave zvinonakidza kuona kuti izvi zvinokonzeresa zvichaitwa sei mumaseketi emagetsi.
