Munyaya yezvinhu zvemhando yepamusoro, vaongorori vari kugara vachitsvaga miganhu mitsva vachitsvaga zvinhu zvine hunhu hwakasiyana zvinogona kuchinja maindasitiri akasiyana-siyana. Chimwe chezvinhu zvinoshamisa zvakadaro ihexagonal boron nitride (h-BN). Inowanzonzi "zvinhu zvinoshamisa," hexagonal boron nitride iri kuwedzera simba sechinhu chinoshandiswa zvakasiyana-siyana chine mashandisirwo akasiyana-siyana. Ngationgororei zvakadzama nyika yehexagonal boron nitride uye tiongorore hunhu hwayo hwakasiyana uye kugona kwayo kunonakidza.
Chii chinonzi hexagonal boron nitride?
Hexagonal boron nitride chinhu chinoumbwa nemaatomu eboron nenitrogen akaenzana akarongwa muchimiro chehexagonal lattice. Chimiro chayo chakafanana negraphite, asi hunhu hwayo hwakasiyana zvakanyanya nezvinhu zvakagadzirwa nekabhoni.
Kufambisa kwakanaka kwekupisa:
Chimwe chezvinhu zvinonyanya kuzivikanwa zve h-BN ndiko kuti ine simba rekupisa rakawanda. Hexagonal boron nitride inogona kufambisa kupisa zvakanaka uku ichichengetedza kuvharwa kwemagetsi. Izvi zvinoita kuti ive yakakosha mumaindasitiri akadai semuchadenga, zvemagetsi uye manejimendi yekupisa.
Muindasitiri yezvemagetsi, boron nitride ine hexagonalyave ichishandiswa sechishandiso chekupisa chinoshanda zvakanaka chinogona kubvisa kupisa kunokonzerwa nemidziyo yemagetsi midiki. Kupisa kwakanyanya kwechigadzirwa ichi kunoita kuti zvikamu zvemagetsi zvigare zvichitonhorera, nokudaro zvichiwedzera kushanda kwazvo uye kugara kwenguva refu.
Kuzora mafuta nekuputira:
Hexagonal boron nitride ine hunhu hwakanaka hwekuzora. Ine coefficient shoma yekukweshana, zvichiita kuti ive mafuta akanaka kwazvo akaoma. Chinhu ichi chave chichishanda mumaindasitiri akasiyana-siyana, anosanganisira mota, ndege nekugadzira zvinhu.
Pamusoro pezvo, h-BN inoshandiswa zvakanyanya sechinodzivisa kunamira mumashandisirwo anosanganisira maitiro ekupisa kwakanyanya. Kukwanisa kwechigadzirwa ichi kutsungirira kupisa kwakanyanya pasina kusangana nezvimwe zvinhu kunoita kuti chive chakakodzera kupfekedzwa pazvigadziko, mapundu, nezvimwe zvinoshandiswa mukugadzira simbi negirazi.
Zvimiro zveDielectric uye Zvemagetsi:
Nekuda kwekugona kwayo kudzivirira kupisa kwemagetsi, h-BNyakawana mashandisirwo mumagetsi. Kusasimba kwayo zvakanyanya kumagetsi kunoita kuti pave nema insulators akavimbika uye anofambisa kupisa. Izvi zvinopa mikana yekugadzira zvishandiso zvemagetsi zvinoshanda uye zvidiki zvakaita sema transistors ane simba guru uye ma circuits akabatanidzwa.
Substrate yemhando yepamusoro:
Hexagonal boron nitrideinowanzoshandiswa sechikamu chepasi pesimba mukukura kwakasiyana-siyana. Maumbirwo ayo ekristaro anopa hwaro hwakakodzera hwekukura kwezvimwe zvinhu mu epitaxial, kusanganisira graphene nezvimwe zvinhu zvine mativi maviri. Izvi zvinovandudza mhando yezvinhu uye zvinogadzira nzira yekushandisa michina yemagetsi neoptoelectronic.
mhedziso:
Nehunhu hwakanaka hwakadai sekugona kupisa, kugona kukwiza mafuta, kugona kwe dielectric uye hunhu hwepamusoro hwe substrate, hexagonal boron nitride ine mukana mukuru mumaindasitiri akasiyana-siyana. Sezvo vaongorori vachiramba vachiongorora nekudzidza nezvechinhu ichi chinoshamisa, chinogona kuwana mamwe mashandisirwo anonakidza mune ramangwana.
Kubva pakutarisira kupisa uye mafuta mukugadzira kusvika kumagetsi akawedzerwa uye zvinhu zvinokura zvemhando yepamusoro, hexagonal boron nitride inopa mikana isingaverengeki yekuvandudza matekinoroji aripo uye kugonesa mhinduro itsva. Sezvo nyika ichigamuchira zvinhu zvinogara kwenguva refu uye zvemhando yepamusoro, hexagonal boron nitride ichaita basa rakakosha mukuumba ramangwana.
