Icandelo lokuQala: Umsebenzi waMalungu eVacuum
Ngokwembali, ukuzalwa kwezixhobo ze-MBE kudlule inkqubo ende.I-evaporation yokuqala ye-photochemical evaporation kunye neendlela zokunyibilika zingalandelwa emva kwe-1950s, kodwa ezi ndlela zinemida emininzi.Emva kwexesha, i-molecular beam epitaxy yabakho kwaye yakhawuleza yaba yeyona ndlela isetyenziswa kakhulu, kwaye ikwabonelela ngamathuba amatsha ophuhliso kunye nokuveliswa kwamalungu omgodi wevacuum.
Igumbi lokucoca kwizixhobo ze-MBE licandelo elibalulekileyo elinokubonelela ngobume be-vacuum obugqibeleleyo ukuqinisekisa umgangatho kunye nokuzinza kokukhula kwezinto eziphathekayo.La magumbi okucoca afuna umoya ophezulu, ukunyamezela uxinzelelo kunye nokuzinza kwe-thermal, kwaye zenziwe kusetyenziswa izinto ezikhethekileyo kunye nobuchule.
Elinye icandelo elibalulekileyo yivacuum valve, esebenza njengetywina kwaye ilawula uxinzelelo lwe-vacuum kwisixhobo se-MBE.Ukuze kuqinisekiswe ukuchaneka okuphezulu kunye nokuthembeka kwesixhobo, iivalve ze-vacuum kufuneka zibe nokutywinwa okugqwesileyo kunye nokutshintsha ngokuchaneka, kwaye zenziwe kusetyenziswa izinto eziphezulu kunye nobuchule bokuvelisa.
Icandelo lesiBini: Inkqubo yokwenziwa koMveliso yaMalungu eVacuum
Ukuvelisa amacandelo egumbi lokufunxa kufuna inkqubo yokuvelisa ephucukileyo.Iimfuno zokukhetha izinto ezichanekileyo, iteknoloji yokucubungula, ukuchaneka kwe-dimensional kunye nokugqitywa komphezulu kuphezulu kakhulu.Kwangaxeshanye, izixhobo eziphambili kunye neteknoloji ziyafuneka ukuze kuqinisekiswe umgangatho kunye nokuzinza kwemveliso.Umzekelo, ukukhethwa kwezinto kufuneka kuthathelwe ingqalelo izinto ezahlukeneyo ezifana nobushushu obuphezulu, ubushushu obuphantsi kunye nokubola kweekhemikhali, kunye netekhnoloji yokucubungula kufuneka iqinisekise ukuchaneka komda kunye nokugqitywa komphezulu, okufuna izixhobo eziphambili kunye netekhnoloji ukufezekisa.Kwangaxeshanye, kukho ubuchwephesha bokuchaneka okuphezulu, njengokusetyenzwa kwe-laser, ukusetyenzwa kwe-electrochemical, njl.
Ngophuhliso oluqhubekayo lwetekhnoloji ye-MBE, imfuno yamalungu egumbi le-vacuum nayo iyanda.Akunakwenzeka kuphela ukuba badlale indima ebalulekileyo ekukhuleni kwezixhobo ze-semiconductor, kodwa zingasetyenziselwa kwezinye izicelo, ezifana nokuveliswa kwezinto eziphezulu ze-optical, izinto ze-semiconductor, njl. Kwintsimi ye-biomedicine, iteknoloji yokukhula kwezinto eziphathekayo. ingasetyenziselwa ukwenza izicubu ezenziweyo, ukulungisa iziphene zezicubu, njl., kwaye inethemba elibanzi lokusetyenziswa.
Ukongeza kwiinkalo ezahlukeneyo zezicelo, iingenelo zeteknoloji yokukhula kwezinto ziquka inkqubo yokulungiselela elula, ukulawulwa okunamandla, ixabiso eliphantsi, isantya sokulungiselela ngokukhawuleza njalo njalo.Ezi zibonelelo zenza ukuba itekhnoloji yokukhula kwezinto ichaphazeleke ngokubanzi kwaye isetyenziswe.
Icandelo lesithathu: Umngeni wokukhula kweteknoloji
Nangona kunjalo, itekhnoloji yokukhula kwezinto eziphathekayo nayo ijongene nemingeni ethile kwinkqubo yesicelo.Okokuqala, inkqubo yokukhula kwezixhobo isoloko ichatshazelwa zizinto ezininzi, ezifana nobushushu, uxinzelelo, umoya, ukuxinana kwe-reactant, njl njl. .Okwesibini, iingxaki ezinjengokukhula okungalinganiyo kunye neziphene zekristale zinokwenzeka ngexesha lenkqubo yokukhula kwezinto.Ezi ngxaki kufuneka zichongwe kwaye zisonjululwe ngexesha ngexesha lenkqubo yokukhula, ngaphandle koko ziya kuba nefuthe elibi ekusebenzeni kwezinto.
Ukongeza kwiinkalo ezahlukeneyo zezicelo, iingenelo zeteknoloji yokukhula kwezinto ziquka inkqubo yokulungiselela elula, ukulawulwa okunamandla, ixabiso eliphantsi, isantya sokulungiselela ngokukhawuleza njalo njalo.Ezi zibonelelo zenza ukuba itekhnoloji yokukhula kwezinto ichaphazeleke ngokubanzi kwaye isetyenziswe.
