I-Hexagonal Boron Nitride: I-Multifunctional Wonder Material

Kwinkalo yezinto eziphucukileyo, abaphandi bahlala behlola imida emitsha bekhangela izinto ezineempawu ezikhethekileyo ezinokuguqula imizi-mveliso eyahlukeneyo. Enye into enjalo ingaqhelekanga yi-hexagonal boron nitride (h-BN). Idla ngokubizwa ngokuba “yimathiriyeli emangalisayo,” i-hexagonal boron nitride ifumana amandla njengezinto eziguquguqukayo ezinoluhlu olubanzi lwezicelo. Masingene nzulu kwihlabathi le-hexagonal boron nitride kwaye sijonge iipropathi zayo ezizodwa kunye namandla anomdla.

 Yintoni i-hexagonal boron nitride? 

I-hexagonal boron nitride yikhompawundi eyenziwe ngamalungu alinganayo eboron kunye neeathom zenitrogen ezicwangciswe kwisakhiwo seletile esinehexagonal. Isakhiwo siyafana negraphite, kodwa iimpawu zayo zihluke kakhulu kwizinto ezisekelwe kwikhabhoni.

 I-thermal conductivity egqwesileyo: 

Enye yezona zinto ziphawulekayo ze-h-BN yi-conductivity ephezulu ye-thermal. I-hexagonal boron nitride inokuqhuba ngokufanelekileyo ubushushu ngelixa igcina ukugquma kombane. Le propati yenza ukuba ixabiseke kumashishini afana ne-aerospace, i-electronics kunye nolawulo lwe-thermal.

Kwishishini le-elektroniki,i-boron nitride enehexagonal isetyenziswe njengesixhobo esisebenza kakhulu sokutshisa ubushushu esikwaziyo ukutshabalalisa ubushushu obuveliswa zizixhobo zombane ezihlangeneyo. Isixhobo esihle kakhulu sokusebenza kwe-thermal siqinisekisa ukuba izinto ze-elektroniki zihlala zipholile, ngaloo ndlela zandisa ukusebenza kwazo kunye nokuphila ixesha elide.

 Ukuthambisa kunye nokwaleka: 

I-hexagonal boron nitride ikwabonisa iimpawu ezigqwesileyo zokuthambisa. Ine-coefficient ephantsi yokukhuhlana, iyenza ibe yeyona nto ibalaseleyo yokuthambisa eyomileyo. Eli nqaku lifumene izicelo kumashishini amaninzi, kubandakanywa iimoto, i-aerospace kunye nemveliso.

Ukongezelela, i-h-BN isetyenziswa ngokubanzi njenge-anti-stick coating kwizicelo ezibandakanya iinkqubo eziphezulu zokushisa. Isakhono semathiriyeli sokumelana namaqondo obushushu agqithisileyo ngaphandle kokusabelana nezinye izinto zenza ukuba zilungele ukugquma kwiintsimbi ezikroliweyo, ukubumba, kunye nezinye izixhobo ezisetyenziselwa ukuphosa ngentsimbi kunye nokwenza iiglasi.

 Iipropati zeDielectric kunye ne-Electronics: 

Ngenxa yobuchule bayo bokugquma umbane,h-BN ufumene usetyenziso kwizinto zombane. Ukuchasana kwayo okuphezulu kumbane wombane kwenza ukuba kudalwe i-insulators ethembekileyo kunye ne-thermal conductive. Oku kubonelela ngamathuba okuphuhliswa kwezixhobo zombane ezisebenza ngokufanelekileyo, ezifana neetransistors ezinamandla aphezulu kunye neesekethe ezidibeneyo.

 Umgangatho ophezulu wesubstrate: 

 I-hexagonal boron nitride isoloko isetyenziswa njenge substrate kwiinkqubo ezahlukeneyo zokukhula. Isakhiwo sayo se-crystal sibonelela ngesiseko esifanelekileyo sokukhula kwe-epitaxial kwezinye izinto, kubandakanywa igraphene kunye nezinye izinto ezimbini-dimensional. Oku kuphucula umgangatho wezinto kwaye kuhlahle indlela ye-electronics kunye ne-optoelectronic applications.

ukuququmbela:

Ngeepropathi ezigqwesileyo ezifana ne-thermal conductivity, amandla okuthambisa, amandla e-dielectric kunye nepropathi ekumgangatho ophezulu we-substrate, i-hexagonal boron nitride inamandla amakhulu kuluhlu olubanzi lwamashishini. Njengoko abaphandi beqhubeka nokuphonononga kwaye befunda malunga nale nto imangalisayo, inokufumana usetyenziso olunomdla ngakumbi kwixesha elizayo.

Ukusuka kulawulo lwe-thermal kunye nokuthambisa kwimveliso ukuya kwi-elektroniki ephuculweyo kunye ne-substrates yokukhula ekumgangatho ophezulu, i-hexagonal boron nitride ibonelela ngamathuba amaninzi okuphucula itekhnoloji esele ikho kunye nokwenza izisombululo ezitsha. Njengoko ihlabathi lisamkela izinto ezizinzileyo neziphucukileyo, i-hexagonal boron nitride iya kudlala indima ebalulekileyo ekubumbeni ikamva.
