Ngokufana negraphene, i-MXenes yintsimbi ye-carbide-dimensional material eyenziwe ngamacandelo e-titanium, i-aluminium, kunye ne-athomu ye-carbon, nganye inesakhiwo sayo esizinzile kwaye sinokuhamba ngokulula phakathi kweengqimba.NgoMatshi ka-2021, iYunivesithi yaseMissouri State yeSayensi kunye neTekhnoloji kunye neArgonne National Laboratory yenze uphando malunga nemathiriyeli yeMXenes kwaye yafumanisa ukuba izinto ezichasene nokunxiba kunye nokuthambisa kwesi sixhobo kwindawo ezingqongileyo ezigqithisileyo zingcono kunezithambisi ezisekelwe kwi-oyile, kwaye zinokusetyenziswa njenge "I-Lubricant Super" yokunciphisa ukunxiba kwiiprobes ezizayo ezifana nokunyamezela.
Abaphandi balinganisa indawo yendawo, kwaye iimvavanyo ze-friction zezinto ezibonakalayo zifumene ukuba i-friction coefficient ye-MXene interface phakathi kwebhola yensimbi kunye ne-silica-coated disc eyenziwe "kwi-superlubricated state" yayiphantsi njenge-0.0067 njenge-0.0017.Iziphumo ezingcono zafunyanwa xa igraphene yongezwa kwiMXene.Ukongezwa kwegraphene kunokunciphisa ngakumbi ukungqubuzana nge-37.3% kunye nokunciphisa ukuguga nge-2 ngaphandle kokuchaphazela iimpawu ze-MXene superlubrication.Izinto zeMXenes zilungelelaniswe kakuhle kwiindawo eziphakamileyo zokushisa, ukuvula iingcango ezintsha zokusetyenziswa kwixesha elizayo lokuthambisa kwiindawo ezigqithiseleyo.
Inkqubela phambili yophuhliso lwenkqubo yokuqala ye-2nm chip e-United States yabhengezwa
Umceli mngeni oqhubekayo kwishishini le-semiconductor kukwenza kwangaxeshanye ii-microchips ezincinci, ezikhawulezayo, ezinamandla kunye nezonga amandla.Uninzi lweetshiphusi zekhompyuter ezisebenzisa izixhobo zamandla namhlanje zisebenzisa itekhnoloji yenkqubo ye-10 okanye i-7-nanometer, kunye nabavelisi abathile bavelisa iitshiphusi ze-5-nanometer.
NgoMeyi ka-2021, i-IBM Corporation yase-United States ibhengeze inkqubela phambili yophuhliso lwe-chip yokuqala yehlabathi ye-2nm.I-chip transistor ithatha isango le-nanometer elinemigangatho emithathu macala onke (GAA) uyilo, isebenzisa itekhnoloji ephezulu kakhulu ye-ultraviolet lithography ukuchaza ubungakanani obuncinci, ubude besango le-transistor yi-nanometers ezili-12, ukuxinana kokudibanisa kuya kufikelela kwi-333 yezigidi nge-square millimeter, kunye neebhiliyoni ezingama-50 zinokudityaniswa.
I-transistors idibaniswe kwindawo enobungakanani beminwe.Xa kuthelekiswa ne-chip ye-7nm, i-chip yenkqubo ye-2nm kulindeleke ukuba iphucule ukusebenza kwe-45%, ukunciphisa ukusetyenziswa kwamandla nge-75%, kwaye inokwandisa ubomi bebhetri beefowuni eziphathwayo ngamaxesha amane, kwaye ifowuni ephathekayo ingasetyenziswa ngokuqhubekayo iintsuku ezine. ngentlawulo enye kuphela.
Ukongeza, i-chip yenkqubo entsha inokuphucula kakhulu ukusebenza kweekhompyuter ze-notebook, kubandakanywa nokuphucula amandla okusebenza kwesicelo kwiikhompyuter ze-notebook kunye nesantya sokufikelela kwi-Intanethi.Kwiimoto eziziqhubayo, ii-chips ze-2nm zenkqubo zinokuphucula amandla okubona into kunye nokunciphisa amaxesha okuphendula, okuya kukhuthaza kakhulu ukuphuhliswa kwentsimi ye-semiconductor kwaye iqhube i-legend yoMthetho kaMoore.I-IBM iceba ukuvelisa i-chips zenkqubo ye-2nm ngo-2027.
