Ukudalwa kunye nokuphuhliswa kwezixhobo zokugcinwa okungaguqukiyo kwedatha yedijithali kuye kwaqhubeka iminyaka emininzi. Impumelelo yokwenyani yenziwa ngaphantsi kweminyaka engama-20 eyadlulayo yinkumbulo ye-NAND, nangona uphuhliso lwayo lwaqala kwiminyaka engama-20 ngaphambili. Namhlanje, malunga nesiqingatha senkulungwane emva kokuqala kophando olukhulu, ukuqala kwemveliso kunye nemigudu eqhubekayo yokuphucula i-NAND, olu hlobo lwememori lusondele ekupheliseni amandla alo ophuhliso. Kuyimfuneko ukubeka isiseko sokutshintshela kwenye iseli yememori enamandla angcono, isantya kunye nezinye iimpawu. Ngexesha elide, inkumbulo enjalo inokuba luhlobo olutsha lwenkumbulo ye-ferroelectric.
I-Ferroelectrics (igama elithi ferroelectrics lisetyenziswa kuncwadi lwangaphandle) zii-dielectrics ezinenkumbulo yendawo yombane esetyenzisiweyo okanye, ngamanye amazwi, zibonakaliswa ngokushiyeka kwe-polarization yeentlawulo. Inkumbulo yeFerroelectric ayikho into entsha. Umceli mngeni yayikukunyusa iiseli ze-ferroelectric ukuya kwinqanaba le-nanoscale.
Kwiminyaka emithathu edlulileyo, izazinzulu kwi-MIPT itekhnoloji yokuvelisa imathiriyeli yefilimu encinci yenkumbulo ye-ferroelectric esekwe kwi-hafnium oxide (HfO2). Oku kwakhona ayiyomathiriyeli yodwa. Le dielectric isetyenziswe iminyaka emininzi emihlanu ngokulandelelana ukwenza ii-transistors ngamasango esinyithi kwiiprosesa kunye nezinye iingqiqo zedijithali. Ngokusekelwe kwiifilimu ze-alloy polycrystalline ze-hafnium kunye ne-zirconium oxides kunye nobukhulu be-2,5 nm ecetywayo kwi-MIPT, kwakunokwenzeka ukudala utshintsho kunye neempawu ze-ferroelectric.
Ukuze i-ferroelectric capacitors (njengoko yaqala ukubizwa kwi-MIPT) ukuba isetyenziswe njengeeseli zememori, kuyimfuneko ukufezekisa i-polarization ephezulu kakhulu, efuna uphononongo olunzulu lweenkqubo zomzimba kwi-nanolayer. Ngokukodwa, fumana umbono wokusasazwa kwamandla ombane ngaphakathi kwinqanaba xa kusetyenziswa i-voltage. Kuze kube kutshanje, izazinzulu zinokuthembela kuphela kwisixhobo semathematika ukuchaza le nto, kwaye ngoku kuphela ubuchule buphunyeziwe apho kwakunokwenzeka ngokoqobo ukukhangela ngaphakathi kwezinto ngexesha lenkqubo yento.
Ubuchule obucetywayo, obusekwe kwi-X-ray ye-photoelectron spectroscopy ene-high-energy, inokuphunyezwa kuphela kufakelo olukhethekileyo (i-synchrotron accelerators). Le ifumaneka eHamburg (eJamani). Zonke iimvavanyo ezine-hafnium oxide-based "ferroelectric capacitors" ezenziwe kwi-MIPT zenzeka eJamani. Inqaku malunga nomsebenzi owenziweyo lapapashwa kwi .
"I-Ferroelectric capacitors edalwe kwilebhu yethu, ukuba isetyenziselwa ukuveliswa kweeseli zememori ezingaguquguqukiyo, inokubonelela ngemijikelezo yokubhala kwakhona i-1010 - ikhulu lamawaka eliphindwe kabini kunokuba ikhompyuter yanamhlanje ivumela," utshilo u-Andrei Zenkevich, omnye wababhali bencwadi. umsebenzi, intloko yebhubhoratri yezinto ezisebenzayo kunye nezixhobo ze-nanoelectronics MIPT. Ngaloo ndlela, kuye kwathathwa elinye inyathelo elibhekiselele kwinkumbulo entsha, nangona kusekho amanyathelo amaninzi, amaninzi amele athathwe.
