Emkhakheni wezinto ezithuthukisiwe, abacwaningi bahlala behlola imingcele emisha befuna izinto ezinezakhiwo ezingavamile ezingaguqula izimboni ezahlukene. Enye yezinto ezingavamile kangaka yi-hexagonal boron nitride (h-BN). Ngokuvamile ibizwa ngokuthi “izinto ezimangalisayo,” i-hexagonal boron nitride iyanda njengezinto eziguquguqukayo ezinezinhlelo zokusebenza eziningi. Ake singene shí ezweni le-hexagonal boron nitride futhi sihlole izakhiwo zayo eziyingqayizivele kanye namandla ayo ajabulisayo.
Kuyini i-hexagonal boron nitride?
I-Hexagonal boron nitride iyinhlanganisela eyakhiwe izingxenye ezilinganayo ze-boron kanye nama-athomu e-nitrogen ahlelwe ngesakhiwo se-hexagonal lattice. Ifana ne-graphite ngokwesakhiwo, kodwa izakhiwo zayo zihluke kakhulu ezintweni ezisekelwe ku-carbon.
Ukushisa okuhle kakhulu:
Esinye sezimpawu eziphawuleka kakhulu ze-h-BN ukuhanjiswa kwayo okuphezulu kokushisa. I-hexagonal boron nitride ingahambisa ukushisa ngempumelelo ngenkathi igcina ukufudumala kukagesi. Lesi sici siyenza ibe usizo kakhulu ezimbonini ezifana nezindiza, izinto zikagesi kanye nokuphathwa kokushisa.
Embonini ye-elekthronikhi, i-nitride ye-boron enezinhlangothi eziyisithuphaisetshenziswe njengento yokushisa esebenza kahle kakhulu ekwazi ukuqeda ukushisa okukhiqizwa amadivayisi kagesi aqinile. Ukushisa okuhle kakhulu kwale nto kuqinisekisa ukuthi izingxenye ze-elekthronikhi zihlala zipholile, ngaleyo ndlela kwandise ukusebenza kwazo kanye nobude bazo.
Ukugcotshwa kanye nokwembozwa:
I-hexagonal boron nitride nayo ibonisa izakhiwo ezinhle kakhulu zokugcoba. Ine-coefficient ephansi yokungqubuzana, okwenza ibe ukugcoba okomile okuhle kakhulu. Lesi sici sithole ukusetshenziswa ezimbonini eziningi, okuhlanganisa izimoto, izindiza kanye nokukhiqiza.
Ngaphezu kwalokho, i-h-BN isetshenziswa kabanzi njengesembozo esilwa nokunamathela ezinhlotsheni ezifaka izinqubo zokushisa okuphezulu. Ikhono lento yokubekezelela amazinga okushisa aphezulu ngaphandle kokusabela nezinye izinto lenza kube kuhle kakhulu ekumbozweni kwezinto ezisetshenziswa ezitsheni, ezikhumbeni, nakwezinye izinto ezisetshenziswa ekubunjweni kwensimbi nasekwenzeni ingilazi.
Izakhiwo ze-Dielectric kanye ne-Electronics:
Ngenxa yamakhono ayo okuvikela ugesi, h-BNithole ukusetshenziswa kuma-elekthronikhi. Ukumelana kwayo okuphezulu namandla kagesi kwenza kube nokwakhiwa kwama-insulator athembekile futhi aqhuba ukushisa. Lokhu kunikeza amathuba okuthuthukiswa kwamadivayisi kagesi asebenza kahle, aqinile njengama-transistors anamandla amakhulu kanye namasekethe ahlanganisiwe.
I-substrate esezingeni eliphezulu:
I-nitride ye-boron enezinhlangothi eziyisithuphaivame ukusetshenziswa njengesisekelo ezinqubweni ezahlukene zokukhula. Isakhiwo sayo sekristalu sinikeza isisekelo esifanele sokukhula kwe-epitaxial kwezinye izinto, okuhlanganisa i-graphene nezinye izinto ezinezilinganiso ezimbili. Lokhu kuthuthukisa ikhwalithi yezinto futhi kuvula indlela yezinhlelo zokusebenza ezintsha ze-elekthronikhi neze-optoelectronic.
Ekuphetheni:
Njengoba inezakhiwo ezinhle kakhulu ezifana nokushisa, amandla okugcoba, amakhono e-dielectric kanye nezakhiwo ze-substrate ezisezingeni eliphezulu, i-hexagonal boron nitride inamandla amakhulu ezimbonini eziningi. Njengoba abacwaningi beqhubeka nokuhlola nokufunda ngale nto emangalisayo, ingathola izinhlelo zokusebenza ezijabulisa kakhulu esikhathini esizayo.
Kusukela ekuphathweni kokushisa kanye nokugcotshwa ekukhiqizeni kuya kuma-elekthronikhi athuthukisiwe kanye nezindawo zokukhula ezisezingeni eliphezulu, i-hexagonal boron nitride inikeza amathuba amaningi okuthuthukisa ubuchwepheshe obukhona kanye nokuvumela izixazululo ezintsha. Njengoba umhlaba wamukela izinto ezisimeme nezithuthukile, i-hexagonal boron nitride izodlala indima ebalulekile ekwakheni ikusasa.
