Kooban oo ka mid ah nambarka molikalic-ka (mbe)
Teknolojiyadda Moloculal Chipitaxy (MBE) ayaa la soo saaray 1950-meeyadii si loogu diyaariyo agab filim oo dhuuban oo loo adeegsado tikniyoolajiyadda uumi baxa. Iyada oo la horumarinayo tikniyoolajiyadda foosha xumaa ee ultra-sare, dalabka tikniyoolajiyadda ayaa loo fidiyay garoonka sayniska semiconductor.
Dhimashada agabka semiconductor Cilmi baarista waa baahida loo qabo aalado cusub, kaas oo laga yaabo inuu horumariyo waxqabadka nidaamka. Dhanka kale, tikniyoolajiyadda maaddada cusub waxay soo saari kartaa qalab cusub iyo teknolojiyad cusub. MOLESALLE CHUSTAXY Eispipitaxy (MBE) waa tikniyoolajiyad faakimaad sare leh oo loogu talagalay lakabka eisxial-ka (badiyaa semiconductor) koritaanka. Waxay isticmaashaa kalluunka kuleylka ah ee atomyada isha ama moleekulada ee saameeya hal-ka-dhigga keli ah. Astaamaha baahsan ee hawsha ayaa u oggolaanaya in-wax-ka-dhexgalka bulshada iyo koritaanka agabyada ku jira meelaha semiconductor ee dhowaan ku dhagan yihiin, taasoo dhalisay in si ka soo horjeedo wasakhaysan.
Teknolojiyadda MBE
Shexa-molikal ceepipitaxy-ka waxaa lagu fuliyay meel bannaan ama meel bannaan oo sare (1 x 10-8PA) Deegaanka. Qaybta ugu muhiimsan ee nalka molital ceepipitaxy waa heerka gelitaankeeda hoose, kaas oo sida caadiga ah u oggolaanaya filimka si uu u koriyo sicirka wax ka yar 3000 nm saacaddii. Heerka dhigashada ee noocan oo kale ah wuxuu u baahan yahay faakuum aad u sareeya oo uu ku gaaro isla heerka nadaafadda ee qaababka kale ee dhigashada.
Si aad ula kulanto bannaanka ulaha kore ee kor lagu sharaxay, aaladda MBudsen (unugyada Knudsen) waxay leedahay lakab qabow, bey'adda fiilooyinka ee ugu sarreysa ee qolka koritaanka waa in lagu ilaaliyaa nidaamka wareegga dareeraha ah ee dareeraha ah. Cudurka dareeraha ah ee dareeraha ah ayaa qaboojiya heerkulka gudaha ee aaladda 77 kelvin (-196 ° C). Jawiga hoose ee heerkulka ayaa sii yareyn kara nuxurka ciladaha ee vacuum wuxuuna bixin doonaa xaalado ka fiican dhigashada filimada filimada khafiifka ah. Sidaa darteed, nidaamka wareejinta dareeraha ee dareeraha ah ee dareeraha ah ayaa looga baahan yahay in qalabka MBE uu bixiyo si joogto ah oo joogto ah oo ah -196 ° C dareere ah dareere.
Nidaamka wareegga dareeraha dareeraha ah ee dareeraha ah
FACUWUM FARSAMADA FARSAMADA FARSAMADA NITROGEN NITROGEN NITROGEN BULSHADA badiyaa waxaa ka mid ah,
● Teegaanka Crynogenic
● Manuumka ugu weyn iyo laanta ee tuubbada tuubbooyinka ka tuura
● Wejiyada gaarka ah ee 'MBE' iyo FACUMUMBAMUM TITPEPSE
● vacum vacuum kala duwan
● Caruurta gaaska gaaska
● filterka jaakada bannaanka
● Nidaamka matoorka mashiinka ah ee firfircoon
● Nidaamka kuleylka saliidda ah iyo nidaamka kuleylka
Shirkadda Qalabka Qalabka ee HL Scrygogenic ayaa ogaatay in la qabto nidaamka qaboojinta dareeraha ah ee Mberogen ee NIPROGEN.edNidaamka tuubooyinka, oo loo adeegsaday shirkado badan, jaamacado iyo machadyada cilmi-baarista.
Qalabka HL Corakogenic
Qalabka HL ee asaasay ee la aasaasay sanadkii 1992 waa astaan xiriir ku leh Chengdu Quduuska Qalabka Chengdu Quduuska ah ee Shiinaha. Qalabka HL dhir udgoon waxaa ka go'an naqshadda iyo soo-saarista faakuumka sare ee foomamka ah ee nidaamka tuubbada tuubbada leh iyo qalabka taageerada la xiriira.
