Nkenke nke Molecular Beam Epitaxy (MBE)
Emepụtara teknụzụ Molecular Beam Epitaxy (MBE) n'afọ ndị 1950 iji kwadebe ihe nkiri ihe nkiri dị mkpa nke semiconductor site na iji teknụzụ ikuku evaporation. Na mmepe nke ultra-high vacuum technology, etinyere ngwa nke teknụzụ ruo na ngalaba sayensị semiconductor.
Ihe mkpali nke nchọpụta ihe semiconductor bụ ọchịchọ maka ngwaọrụ ọhụrụ, nke nwere ike imeziwanye arụmọrụ nke usoro ahụ. N'aka nke ya, nkà na ụzụ ihe ọhụrụ nwere ike ịmepụta ngwá ọrụ ọhụrụ na nkà na ụzụ ọhụrụ. Molecular beam epitaxy (MBE) bụ teknụzụ oghere dị elu maka uto epitaxial oyi akwa (na-abụkarị semiconductor). Ọ na-eji ọkụ ọkụ nke atọm isi iyi ma ọ bụ ụmụ irighiri ihe na-emetụta otu mkpụrụ kristal. Njirimara oghere dị oke elu nke usoro a na-enye ohere ịmegharị ọnọdụ na uto nke ihe mkpuchi n'elu elu semiconductor tolitere ọhụrụ, na-ebute oghere na-enweghị mmetọ.
MBE teknụzụ
A na-eme epitaxy molecular beam na oghere dị elu ma ọ bụ oghere dị elu (1 x 10).-8Pa) gburugburu ebe obibi. Akụkụ kachasị mkpa nke molecular beam epitaxy bụ obere ntinye ego ya, nke na-enyekarị ohere ka ihe nkiri ahụ na-eto eto na-erughị 3000 nm kwa elekere. Ọnụ ego nkwụnye ego dị otú ahụ na-achọ oghere zuru oke iji nweta otu ọkwa ịdị ọcha dị ka ụzọ nkwụnye ego ndị ọzọ.
Iji zute oghere ultra-high nke akọwara n'elu, ngwaọrụ MBE (Knudsen cell) nwere oyi akwa oyi, na ebe a na-ekpo ọkụ na-ekpo ọkụ nke nnukwu ụlọ na-eto eto aghaghị ịnọgide na-eji usoro mgbasa ozi nitrogen mmiri mmiri. Mmiri mmiri nitrogen na-eme ka okpomọkụ dị n'ime ngwaọrụ dị jụụ ruo 77 Kelvin (-196 Celsius C). Ọnọdụ okpomọkụ dị ala nwere ike ibelata ọdịnaya nke adịghị ọcha na oghere ma nye ọnọdụ ka mma maka itinye ihe nkiri dị mkpa. Ya mere, a chọrọ usoro mgbasa ozi ikuku nitrogen nke raara onwe ya nye maka akụrụngwa MBE iji nye ihe na-aga n'ihu ma na-adịgide adịgide nke -196 Celsius.
