I-Molecular Beam Epitaxy (MBE) bubuchule obuchaneke kakhulu obusetyenziselwa ukwenza iifilimu ezincinci kunye ne-nanostructures kwizicelo ezahlukeneyo, kubandakanywa izixhobo ze-semiconductor, i-optoelectronics, kunye ne-quantum computing. Omnye wemingeni engundoqo kwiinkqubo ze-MBE kukugcina amaqondo obushushu aphantsi kakhulu, aphoumbhobho wevacuum jacketeds (VJP) iza kudlala. Le mibhobho phambili ibalulekile ekuqinisekiseni ulawulo thermal kumagumbi MBE, kubenza icandelo eliyimfuneko ekuphumezeni ukukhula ezikumgangatho ophezulu izinto kumgangatho atomic.
Yintoni i-Molecular Beam Epitaxy (MBE)?
I-MBE bubuchule bokubeka obubandakanya ukubekwa okulawulwayo kweemitha zeathom okanye zemolekyuli kwi-substrate kwindawo enevacuum ephezulu. Inkqubo idinga ulawulo oluchanekileyo lokushisa ukufezekisa izinto eziphathekayo ezifunwayo, okwenza ulawulo lwe-thermal lube yinto ebalulekileyo. Kwiinkqubo ze-MBE,imibhobho yokufunxa ibhatyizisetyenziselwa ukuthwala i-cryogenic liquids kunye neegesi, ukuqinisekisa ukuba i-substrate ihlala kwiqondo lokushisa elifanelekileyo ngexesha lenkqubo yokubeka.
Indima yeMibhobho eneJacket yeVacuum kwiiNkqubo zeMBE
Kwitekhnoloji ye-MBE,imibhobho yokufunxa ibhatyizisetyenziswa ikakhulu ukuthutha cryogens ezifana nitrogen engamanzi kunye helium engamanzi ukupholisa igumbi MBE kunye amacandelo ezinxulumene. Imibhobho iquka umbhobho wangaphakathi obambe i-cryogenic liquid, ejikelezwe yijacket ye-insulating yangaphandle kunye ne-vacuum layer. Oku kugqunywa kwevacuum kunciphisa ukuhanjiswa kobushushu, kuthintela ukuguquguquka kobushushu kunye nokuqinisekisa ukuba inkqubo igcina amaqondo obushushu asezantsi kakhulu afunekayo kwi-MBE.
Izinto eziluncedo zokuSebenzisa iMibhobho yeJacket yeVacuum kwi-MBE Technology
Ukusetyenziswa kweimibhobho yokufunxa ibhatyikwitekhnoloji ye-MBE ibonelela ngeenzuzo ezininzi. Okokuqala, baqinisekisa ulawulo oluchanekileyo lwe-thermal olufunekayo kwikhwalithi ephezulu yokubekwa kwefilimu ebhityileyo, ebaluleke kakhulu ekufezekiseni ukukhula kwezinto ezifanayo. Okwesibini, banceda ukunciphisa umngcipheko wokungcoliswa kwimeko ye-MBE ngokugcina ingqibelelo ye-vacuum. Okokugqibela,imibhobho yokufunxa ibhatyiukuphucula ukusebenza kakuhle kwenkqubo ye-MBE ngokunciphisa ukubilisa kolwelo lwe-cryogenic, okukhokelela kwiindleko zokusebenza eziphantsi kunye nexesha elide lokuphila kwenkqubo.
Ikamva leMibhobho yeJacket yeVacuum kwi-MBE Applications
Njengoko itekhnoloji ye-MBE iqhubeka nokuvela kwaye iimfuno zokuchaneka okuphezulu zikhula,imibhobho yokufunxa ibhatyiiya kudlala indima ebaluleke ngakumbi. Ukwenziwa kwezinto ezintsha kwimathiriyeli yokugquma kunye noyilo kuya kuphucula ngakumbi ukusebenza kwale mibhobho, kuphuculwe ukusebenza kakuhle kwamandla kweenkqubo ze-MBE kunye nokwenza ukuba ukwenziwa kwezinto ezikumgangatho ophezulu ngakumbi. Njengoko amashishini afana nokuveliswa kwe-semiconductor kunye ne-quantum computing iqhubeka nokwanda, imfuno yezisombululo ezithembekileyo nezisebenzayo zokulawula ukushisa, ezifanaimibhobho yokufunxa ibhatyi, iya kukhula kuphela.
Ukuququmbela,imibhobho yokufunxa ibhatyiziyinxalenye ebalulekileyo kwinkqubo ye-MBE, evumela ulawulo lobushushu oluchanekileyo kunye nokuqinisekisa ukubekwa ngempumelelo kweefilimu ezibhityileyo ezikumgangatho ophezulu. Njengoko imfuno yezinto eziphambili ziqhubeka nokunyuka, le mibhobho iya kuhlala ibalulekile ekugcineni imimandla ephantsi yobushushu obufunekayo kwi-teknoloji ye-MBE yokusika.
