Ngwa MBE dakọtara

Ebe ọ bụ na 2005, HL Cryogenic Equipment (HL CRYO) na-emeziwanye ma melite usoro a ma na-akwado ndị na-emepụta ngwá ọrụ MBE mba ụwa. Ndị na-emepụta ngwa MBE, gụnyere DCA, REBER, na ụlọ ọrụ anyị na-emekọ ihe. Ndị na-emepụta ngwá ọrụ MBE, gụnyere DCA na REBER, ejikọtala aka n'ọtụtụ ọrụ.

Riber SA bụ onye na-eweta ụwa zuru ụwa ọnụ nke ngwaahịa molecular beam epitaxy (MBE) yana ọrụ ndị metụtara ya maka nyocha semiconductor na ngwa ụlọ ọrụ. Ngwa Riber MBE nwere ike idobe ihe dị oke mkpa na mkpụrụ, yana njikwa dị elu. Ngwá ọrụ na-ekpo ọkụ nke HL Cryogenic Equipment (HL CRYO) nwere Riber SA Ngwá ọrụ kachasị ukwuu bụ Riber 6000 na nke kacha nta bụ kọmpat 21. Ọ dị mma ma ndị ahịa ghọtara ya.

DCA bụ oxide MBE na-eduga n'ụwa. Kemgbe 1993, emebela usoro mmepe nke usoro oxidation, kpo oku mkpụrụ osisi antioxidant na isi mmalite antioxidant.
