Lefapheng la thepa e tsoetseng pele, bafuputsi ba lula ba hlahloba meeli e mecha ba batla lintho tse nang le thepa e ikhethang tse ka fetolang liindasteri tse fapaneng. E 'ngoe ea thepa e ikhethang joalo ke hexagonal boron nitride (h-BN). Hangata e bitsoa "thepa e makatsang," hexagonal boron nitride e ntse e eketseha e le ntho e feto-fetohang e nang le mefuta e mengata ea lits'ebetso. A re hlahlobeng ka botebo lefats'eng la hexagonal boron nitride 'me re hlahlobe thepa ea eona e ikhethang le bokhoni ba eona bo khahlisang.
Boron nitride e nang le mahlakore a tšeletseng ke eng?
Hexagonal boron nitride ke motsoako o entsoeng ka likarolo tse lekanang tsa boron le liathomo tsa naetrojene tse hlophisitsoeng ka sebopeho sa hexagonal lattice. Ka sebopeho sa eona e tšoana le graphite, empa thepa ea eona e fapane haholo le thepa e thehiloeng khaboneng.
Ho tsamaisa mocheso hantle haholo:
E 'ngoe ea litšobotsi tse hlahelletseng tsa h-BN ke ho khanna ha eona mocheso ka mokhoa o phahameng. Hexagonal boron nitride e ka tsamaisa mocheso ka katleho ha e ntse e boloka ho thibela motlakase. Thepa ena e etsa hore e be ea bohlokoa liindastering tse kang tsa lifofane, tsa elektroniki le tsa tsamaiso ea mocheso.
Indastering ea lisebelisoa tsa elektroniki, boron nitride e nang le mahlakore a tšeletsenge sebelisitsoe e le sesebelisoa sa ho futhumatsa se sebetsang hantle haholo se khonang ho qhala mocheso o hlahisoang ke lisebelisoa tse nyane tsa elektroniki. Ho tsamaisa mocheso hantle ha thepa ho netefatsa hore likarolo tsa elektroniki li lula li pholile, ka hona ho eketsa ts'ebetso ea tsona le nako ea tsona ea bophelo bo bolelele.
Setlolo le ho roala:
Hexagonal boron nitride le yona e na le thepa e ntle ya ho tlotsa. E na le coefficient e tlase ya kgohlano, e leng se etsang hore e be setlolo se setle sa ho omisa. Tshebetso ena e se e sebedisetswa diindastering tse ngata, ho kenyeletswa le dikoloi, difofane le tlhahiso.
Ho phaella moo, h-BN e sebediswa haholo e le seaparo se thibelang ho kgomarela ditshebedisong tse kenyeletsang ditshebetso tsa mocheso o phahameng. Bokgoni ba thepa ba ho mamella dithempereichara tse feteletseng ntle le ho kopana le dintho tse ding bo etsa hore e be ntle bakeng sa ho roala hodima dithunya, dibopeho le disebediswa tse ding tse sebediswang ho tjheseletsa ka tshepe le ho etsa khalase.
Thepa ea Dielectric le Elektroniki:
Ka lebaka la bokgoni ba yona ba ho thibela ho kwahela motlakase, h-BNe fumane lits'ebetso tsa elektroniki. Ho hanyetsa ha eona motlakase haholo ho nolofalletsa ho thehoa ha li-insulator tse tšepahalang le tse tsamaisang mocheso. Sena se fana ka menyetla ea nts'etsopele ea lisebelisoa tsa elektroniki tse sebetsang hantle, tse nyane tse kang li-transistors tse matla a phahameng le lipotoloho tse kopaneng.
Substrate ea boleng bo holimo:
Hexagonal boron nitridehangata e sebelisoa e le substrate lits'ebetsong tse fapaneng tsa kholo. Sebopeho sa eona sa kristale se fana ka motheo o loketseng bakeng sa kholo ea epitaxial ea lisebelisoa tse ling, ho kenyeletsoa graphene le lisebelisoa tse ling tsa mahlakore a mabeli. Sena se ntlafatsa boleng ba thepa mme se bula tsela bakeng sa lits'ebetso tse ncha tsa elektroniki le tsa optoelectronic.
ha re phethela:
Ka thepa e ntle haholo e kang ho tsamaisa mocheso, bokgoni ba ho tlotsa, bokgoni ba dielectric le thepa ya boleng bo hodimo ya substrate, nitride ya boron e nang le mahlakore a tsheletseng e na le bokgoni bo boholo diindastering tse fapaneng. Ha bafuputsi ba ntse ba tswela pele ho hlahloba le ho ithuta ka thepa ena e makatsang, e ka fumana ditshebediso tse thabisang le ho feta nakong e tlang.
Ho tloha taolong ea mocheso le ho tlotsa tlhahisong ho ea ho lisebelisoa tsa elektroniki tse ntlafalitsoeng le likarolo tsa kholo ea boleng bo holimo, nitride ea boron e nang le mahlakore a tšeletseng e fana ka menyetla e mengata ea ho ntlafatsa mahlale a teng le ho nolofalletsa litharollo tse ncha. Ha lefats'e le amohela thepa e tsitsitseng le e tsoetseng pele, nitride ea boron e nang le mahlakore a tšeletseng e tla bapala karolo ea bohlokoa ho bopeng bokamoso.
