Incamake y'Uburyo bwo Gupima Umucyo w'Umuyoboro w'Amabara (MBE)
Ikoranabuhanga rya Molecular Beam Epitaxy (MBE) ryakozwe mu myaka ya 1950 kugira ngo ritegure ibikoresho bya semiconductor thin film hakoreshejwe ikoranabuhanga rya vacuum evaporation. Hamwe n'iterambere ry'ikoranabuhanga rya vacuum cleaner riri hejuru cyane, ikoreshwa ry'ikoranabuhanga ryagiye rigera no mu rwego rwa siyansi ya semiconductor.
Impamvu y’ubushakashatsi ku bikoresho bya semiconductor ni ugushaka ibikoresho bishya, bishobora kunoza imikorere ya sisitemu. Na none, ikoranabuhanga rishya ry’ibikoresho rishobora gutanga ibikoresho bishya n’ikoranabuhanga rishya. Molecular beam epitaxy (MBE) ni ikoranabuhanga rikoresha vacuum nyinshi kugira ngo ikure mu cyiciro cya epitaxial (ubusanzwe semiconductor). Ikoresha amashanyarazi y’atomu cyangwa molekile zigira ingaruka ku gice kimwe cya kristu. Imiterere y’amashanyarazi menshi cyane muri iki gikorwa yemerera metallization no gukura kw’ibikoresho bikingira ku buso bushya bwa semiconductor, bigatuma habaho ahantu hatarangwa umwanda.
Ikoranabuhanga rya MBE
Ingufu za molekile zakorewe mu cyuma gishyuha cyane cyangwa mu cyuma gishyuha cyane (1 x 10).-8Pa) ibidukikije. Ikintu cy'ingenzi cyane ku muyoboro wa molekile ni igipimo gito cyo gushyiramo ibintu, akenshi gituma filime ikura ku gipimo kiri munsi ya 3000 nm ku isaha. Igipimo gito cyo gushyiramo ibintu gisaba isuku ihagije kugira ngo igere ku rwego rumwe n'ubundi buryo bwo gushyiramo ibintu.
Kugira ngo ihuze n'ingufu nyinshi cyane zavuzwe haruguru, igikoresho cya MBE (Knudsen cell) gifite urwego rwo gukonjesha, kandi ibidukikije binini cyane by'icyumba cyo gukura bigomba kubungabungwa hakoreshejwe sisitemu yo gukwirakwiza azote y'amazi. Azote y'amazi ikonjesha ubushyuhe bw'imbere bw'igikoresho kugeza kuri 77 Kelvin (−196 °C). Ibidukikije bikonjesha bishobora kugabanya cyane ingano y'imyanda mu mashini kandi bigatanga imiterere myiza yo gushyiramo uduce duto. Kubwibyo, sisitemu yihariye yo gukonjesha azote y'amazi irakenewe kugira ngo ibikoresho bya MBE bitange azote y'amazi ihoraho kandi ihamye ya -196 °C.
Sisitemu yo gukonjesha azote y'amazi
Sisitemu yo gukonjesha azote y'amazi irimo ahanini,
● ikigega cy'amazi gihumanya
● umuyoboro w'ikoti ukoresha icyuma gishyushya amazi n'icyuma gishyushya amazi / umuyoboro w'ikoti ukoresha icyuma gishyushya amazi
● Umuyoboro w'imyotsi uvamo umwuka wihariye wa MBE hamwe n'umuyoboro w'imyotsi uvamo umwuka
● valve zitandukanye zifite ikoti ry'umwuka
● uruzitiro rw'amazi n'umwuka
● akayunguruzo karimo ikoti ry'umwuka
● sisitemu yo gupompa ikoresha umwuka ushyushye
● Gukonjesha no gusukura uburyo bwo kongera gushyushya mbere y'igihe
Isosiyete ya HL Cryogenic Equipment yasanze isabwa rya sisitemu yo gukonjesha azote y'amazi ya MBE, ikagira ikoranabuhanga rigezweho kugira ngo ikore neza sisitemu yihariye yo gukonjesha azote y'amazi ya MBE ku ikoranabuhanga rya MBE hamwe n'ibikoresho byuzuye byo gukingira umuyaga.edsisitemu y'imiyoboro y'amazi, yakoreshejwe mu bigo byinshi, za kaminuza n'ibigo by'ubushakashatsi.
Ibikoresho bya HL Cryogenic
HL Cryogenic Equipment yashinzwe mu 1992 ni ikirango gifitanye isano na Chengdu Holy Cryogenic Equipment Company mu Bushinwa. HL Cryogenic Equipment yiyemeje gushushanya no gukora sisitemu ya High Vacuum Insulated Cryogenic Piping System hamwe n'ibindi bikoresho bifitanye isano.
