Isishwankathelo seMveliso

IItyhubhu yesafire ye-EFG, eyenziwe yiUkukhula kweFilimu echazwe ngokugqithisileyo (EFG)ubuchule, yimveliso ye-single-crystal aluminum oxide (Al₂O₃) eyaziwa ngokuqina kwayo okugqwesileyo, ubumsulwa, kunye nokusebenza kwayo okubonakalayo. Indlela ye-EFG ivumela iityhubhu zesafire ukubaikhule ngokuthe ngqo kwi-geometry yetyhubhu, ivelisa imiphezulu egudileyo kunye nobukhulu bodonga obuhambelanayo ngaphandle kokulungiswa kakhulu emva kokulungiswa. Ezi tyhubhu zesafire zibonisa uzinzo olumangalisayoiindawo ezinobushushu obuphezulu, uxinzelelo oluphezulu, kunye neendawo ezirhabaxa, nto leyo eyenza ukuba zibe yimfuneko kakhulu kwizicelo eziphambili zoshishino nezenzululwazi.

Itekhnoloji yoKhulo lwe-EFG

Inkqubo yokukhula kwe-EFG isebenzisaisixhobo sokufa okanye sokubumbaechaza imida yangaphandle neyangaphakathi yekristale njengoko izinto zesafire ezinyibilikisiweyo zitsalwa phezulu. Ngolawulo oluchanekileyo lwefilimu enyibilikisiweyo etyalwe nge-capillary, ikristale yesafire iyaqina ibe yi-aisilinda esingenamthungo esingenanto.

Le ndlela iqinisekisa ukuba imveliso yokugqibela igcinaubukhulu obufunekayo kunye nolwalathiso lwekristale, ukunciphisa imfuneko yokwenziwa kweminye imisebenzi. Ngenxa yokuba isafire yenziwe ngokuthe ngqo kwimo yayo yokusebenza, inkqubo ye-EFG inikaukuphindaphindwa okuhle kakhulu, isivuno esiphezulu, kunye nokukhula okungabizi kakhuluyemveliso enkulu.

Iimpawu zokusebenza

Uthumelo oluBanzi lwe-Optical:Ithumela ukukhanya ukusuka kwi-ultraviolet (190 nm) ukuya kuluhlu lwe-infrared (5 µm), ilungele ukusetyenziswa kwe-optical, i-analytical, kunye ne-sensing.
Amandla aphezulu oLwakhiwo:Ulwakhiwo lwe-monocrystalline lubonelela ngokumelana okuphezulu noxinzelelo loomatshini, ukutshatyalaliswa kobushushu, kunye nokuguqulwa.
Uzinzo oluKhethekileyo lobushushu:Ingasebenza ngokuqhubekekayo kwiamaqondo obushushu angaphezulu kwe-1700°Cngaphandle kokuthamba, ukuqhekeka, okanye ukonakala kweekhemikhali.
Ukumelana neekhemikhali kunye neplasma:Ii-asidi ezinamandla, ii-alkali, kunye neegesi ezisabelayo ezingasebenziyo ukuya kwi-strong acids, zifanelekile kwiindawo ze-semiconductor kunye nelebhu.
Umgangatho womphezulu ogudileyo:Umphezulu we-EFG osele ukhulile sele ulungile kwaye ufana, uvumela ukupholishwa okanye ukugqunywa nge-optical ukuba kuyimfuneko.
Ixesha Elide Lokuphila Nokugcinwa Okuncinci:Ngenxa yokumelana nokuguguleka kwesafire, iityhubhu ze-EFG zibonelela ngobomi obude nangona zisetyenziswa kakhulu.
