I-Molecular Beam Epitaxy (MBE) yindlela echanekileyo kakhulu esetyenziselwa ukwenza iifilimu ezincinci kunye nezakhiwo ezincinci kwizicelo ezahlukeneyo, kubandakanya izixhobo ze-semiconductor, i-optoelectronics, kunye ne-quantum computing. Enye yeengxaki eziphambili kwiinkqubo ze-MBE kukugcina amaqondo obushushu aphantsi kakhulu, aphoumbhobho ofakwe ijakethi ye-vacuums (VJP) ziyadlala indima. Le mibhobho iphambili ibalulekile ekuqinisekiseni ulawulo lobushushu kumagumbi e-MBE, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo ekufezekiseni ukukhula komgangatho ophezulu kwezinto kwinqanaba le-athomu.
Yintoni iMolecular Beam Epitaxy (MBE)?
I-MBE yindlela yokufaka equka ukufakwa okulawulwayo kwemisebe yeathomu okanye yeemolekyuli kwi-substrate kwindawo ene-vacuum ephezulu. Le nkqubo ifuna ulawulo oluchanekileyo lobushushu ukuze kufezekiswe iipropati zezinto ezifunekayo, nto leyo eyenza ulawulo lobushushu lube yinto ebalulekileyo. Kwiinkqubo ze-MBE,imibhobho enejakethi yokucoca ulwelozisetyenziselwa ukuthwala ulwelo kunye neegesi ezirhabaxa, ukuqinisekisa ukuba isiseko sihlala sikwiqondo lobushushu elifanelekileyo ngexesha lenkqubo yokufakwa.
Indima yeeMbhobho zeVacuum Jacketed kwiiNkqubo ze-MBE
Kwitekhnoloji ye-MBE,imibhobho enejakethi yokucoca ulwelozisetyenziswa kakhulu ukuthutha ii-cryogens ezifana ne-nitrogen engamanzi kunye ne-helium engamanzi ukupholisa igumbi le-MBE kunye nezinto ezinxulumene noko. Le mibhobho yenziwe ngombhobho wangaphakathi obamba ulwelo oluyi-cryogenic, ojikelezwe yijakethi yangaphandle yokukhusela enomaleko we-vacuum. Olu khuselo lwe-vacuum lunciphisa ukudluliselwa kobushushu, luthintele ukutshintshatshintsha kobushushu kwaye luqinisekise ukuba inkqubo igcina amaqondo obushushu aphantsi kakhulu afunekayo kwi-MBE.
Iingenelo zokusebenzisa iipayipi ze-vacuum jacketed kwiTekhnoloji ye-MBE
Ukusetyenziswa kweimibhobho enejakethi yokucoca ulweloKwiteknoloji ye-MBE, zibonelela ngeenzuzo ezininzi. Okokuqala, ziqinisekisa ulawulo oluchanekileyo lobushushu olufunekayo ukuze ifilimu encinci ibekwe kakuhle, nto leyo ibalulekileyo ekufezekiseni ukukhula kwezinto ezifanayo. Okwesibini, zinceda ekunciphiseni umngcipheko wongcoliseko kwindawo ye-MBE ngokugcina ingqibelelo ye-vacuum. Okokugqibela,imibhobho enejakethi yokucoca ulweloukuphucula ukusebenza kakuhle kwenkqubo ye-MBE ngokunciphisa ukubila kolwelo oluyi-cryogenic, okukhokelela ekuncipheni kweendleko zokusebenza kunye nobomi bexesha elide benkqubo.
Ikamva leeMbhobho zeVacuum Jacketed kwiZicelo ze-MBE
Njengoko itekhnoloji ye-MBE iqhubeka nokukhula kwaye iimfuno zokuchaneka okuphezulu zikhula,imibhobho enejakethi yokucoca ulwelokuza kudlala indima ebaluleke ngakumbi. Utshintsho kwizixhobo zokukhusela ubushushu kunye noyilo luya kuphucula ngakumbi ukusebenza kwezi payipi, luphucule ukusebenza kakuhle kwamandla kweenkqubo ze-MBE kwaye luvumele ukwenziwa kwezinto eziphucukileyo ngakumbi. Njengoko amashishini afana nokuvelisa i-semiconductor kunye ne-quantum computing eqhubeka nokukhula, imfuneko yezisombululo zolawulo lobushushu ezithembekileyo nezisebenzayo, ezifanaimibhobho enejakethi yokucoca ulwelo, iya kukhula kuphela.
Ukuququmbela,imibhobho enejakethi yokucoca ulweloziyinxalenye ebalulekileyo kwinkqubo ye-MBE, ezivumela ulawulo oluchanekileyo lobushushu kunye nokuqinisekisa ukufakwa ngempumelelo kweefilimu ezincinci ezikumgangatho ophezulu. Njengoko imfuno yezinto eziphambili iqhubeka nokunyuka, le mibhobho iya kuhlala ibalulekile ekugcineni iimeko zobushushu obuphantsi ezifunekayo kwitekhnoloji ye-MBE yanamhlanje.
