Isishwankathelo se-Molecular Beam Epitaxy (MBE)
Itekhnoloji ye-Molecular Beam Epitaxy (MBE) yaphuhliswa kwi-1950s ukulungiselela i-semiconductor ebhityileyo imathiriyeli yefilimu kusetyenziswa itekhnoloji yokufunxa umphunga. Ngophuhliso lwetekhnoloji ye-vacuum ephezulu kakhulu, ukusetyenziswa kwetekhnoloji kwandisiwe kwinkalo yesayensi ye-semiconductor.
Inkuthazo yophando lwezixhobo ze-semiconductor yimfuno yezixhobo ezitsha, ezinokuphucula ukusebenza kwenkqubo. Ngapha koko, itekhnoloji entsha yezinto eziphathekayo inokuvelisa izixhobo ezitsha kunye neteknoloji entsha. I-molecular beam epitaxy (MBE) yitekhnoloji ephezulu yokucoca i-epitaxial layer (ngokuqhelekileyo i-semiconductor) ukukhula. Isebenzisa umqa wobushushu weathom yomthombo okanye iimolekyuli ezichaphazela i-crystal substrate enye. Iimpawu ze-vacuum eziphezulu kakhulu zenkqubo zivumela i-metalization ye-in-situ kunye nokukhula kwezixhobo zokugquma kwiindawo ezisanda kukhula ze-semiconductor, ezikhokelela kwi-interfaces engenalungcoliseko.
I-MBE Technology
I-epitaxy ye-molecular beam yenziwa kwi-vacuum ephezulu okanye i-vacuum ephezulu kakhulu (1 x 10).-8Pa) okusingqongileyo. Eyona nto ibalulekileyo ye-molecular beam epitaxy yizinga eliphantsi lokubeka, elihlala livumela ifilimu ukuba i-epitaxial ikhule ngesantya esingaphantsi kwe-3000 nm ngeyure. Izinga eliphantsi lokubeka elinjalo lifuna ivacuum ephezulu ngokwaneleyo ukufikelela kwinqanaba elifanayo lokucoceka njengezinye iindlela zokubeka.
Ukuhlangabezana ne-vacuum ephezulu kakhulu echazwe ngasentla, isixhobo se-MBE (iseli ye-Knudsen) inomaleko wokupholisa, kunye ne-ultra-high vacuum ye-vacuum yegumbi lokukhula kufuneka igcinwe kusetyenziswa inkqubo yokujikeleza kwe-nitrogen engamanzi. Initrogen elulwelo ipholisa ubushushu bangaphakathi besixhobo ukuya kutsho kuma-77 Kelvin (−196 °C). Indawo yokushisa ephantsi inokunciphisa ngakumbi umxholo wokungcola kwi-vacuum kwaye ibonelele ngeemeko ezingcono zokubekwa kweefilimu ezincinci. Ke ngoko, inkqubo yokujikeleziswa kwenitrogen yolwelo ezinikeleyo iyafuneka kwisixhobo se-MBE ukubonelela ngobonelelo oluqhubekayo noluzinzileyo lwe- -196 °C yenitrogen engamanzi.
Ulwelo lweNitrogen yokuPholisa iNkqubo yokuBoleka
