Mu makampani opanga zinthu zamagetsi zamagetsi zomwe zimayenda mwachangu, kusunga malo abwino ochitira zinthu zachilengedwe ndikofunikira kwambiri pakupanga zinthu zabwino kwambiri.Molecular Beam Epitaxy (MBE), njira yofunika kwambiri popanga zinthu zopangidwa ndi ma semiconductor, imapindula kwambiri ndi kupita patsogolo kwa ukadaulo woziziritsa, makamaka pogwiritsa ntchito nayitrogeni yamadzimadzi ndimapaipi oteteza utsi (VIP)Blog iyi ikufotokoza za udindo wofunikira waAnthu Olemekezekapakukweza MBEntchito zake, zomwe zikugogomezera kuti zimagwira ntchito bwino komanso kudalirika kwake.
Kufunika Kozizira mu MBE
Molecular Beam Epitaxy (MBE)ndi njira yolamulidwa kwambiri yoyika zigawo za atomiki pa substrate, yofunikira popanga zida za semiconductor monga ma transistors, ma laser, ndi maselo a dzuwa. Kuti tikwaniritse kulondola kwakukulu kofunikira mu MBE, kusunga kutentha kokhazikika ndikofunikira. Nayitrogeni yamadzimadzi nthawi zambiri imagwiritsidwa ntchito pachifukwa ichi chifukwa cha kutentha kwake kochepa kwambiri kwa -196°C, kuonetsetsa kuti substratezo zimakhalabe pa kutentha kofunikira panthawi yoyika.
Udindo wa Nayitrogeni Yamadzimadzi mu MBE
Nayitrogeni yamadzimadzi ndi yofunika kwambiri mu njira za MBE, zomwe zimapangitsa kuti kuziziritsa kukhale kokhazikika komwe kumatsimikizira kuti kutentha kumakhazikika popanda kusintha kosafunikira kwa kutentha. Kukhazikika kumeneku ndikofunikira kwambiri popanga zinthu zapamwamba kwambiri, chifukwa ngakhale kusintha pang'ono kwa kutentha kungayambitse zolakwika kapena kusagwirizana m'magawo a atomu. Kugwiritsa ntchito nayitrogeni yamadzimadzi kumathandiza kukwaniritsa mikhalidwe yokwera kwambiri ya vacuum yomwe imafunika pa MBE, kupewa kuipitsidwa ndikuwonetsetsa kuti zinthuzo ndi zoyera.
Ubwino wa Mapaipi Otetezedwa ndi Vacuum (VIP) mu MBE
Mapaipi oteteza vacuum (VIP)ndi chitukuko chachikulu pa kunyamula bwino kwa nayitrogeni yamadzimadzi. Mapaipi awa adapangidwa ndi vacuum layer pakati pa makoma awiri, kuchepetsa kwambiri kusamutsa kutentha ndikusunga kutentha kwa nayitrogeni yamadzimadzi pamene ikuyenda kuchokera ku malo osungira kupita ku dongosolo la MBE. Kapangidwe kameneka kamachepetsa kutayika kwa nayitrogeni yamadzimadzi chifukwa cha nthunzi, ndikutsimikizira kuti chipangizo cha MBE chili ndi mphamvu yokhazikika komanso yodalirika.
Kuchita Bwino ndi Kusunga Mtengo

Kutaya kutentha kochepa kumatanthauza kuti pakufunika nayitrogeni yochepa yamadzimadzi, zomwe zimachepetsa ndalama zogwirira ntchito komanso zimawonjezera magwiridwe antchito. Kuphatikiza apo, mphamvu zotetezera kutentha zaAnthu Olemekezekazimathandiza kuti malo ogwirira ntchito akhale otetezeka mwa kuchepetsa chiopsezo cha chisanu ndi zoopsa zina zokhudzana ndi kugwiritsa ntchito zinthu zowononga.
Kukhazikika kwa Njira Yowonjezera
Anthu Olemekezekaamaonetsetsa kuti nayitrogeni yamadzimadzi imakhalabe pa kutentha kofanana paulendo wake wonse wopita kuDongosolo la MBEKukhazikika kumeneku ndikofunikira kwambiri pakusunga mikhalidwe yolimba yofunikira popanga semiconductor yolondola kwambiri. Mwa kupewa kusinthasintha kwa kutentha,Anthu OlemekezekaZimathandiza kupanga zigawo zambiri zofanana komanso zopanda chilema za semiconductor, zomwe zimapangitsa kuti zinthu zomaliza zikhale bwino komanso kuti zinthuzo zigwire bwino ntchito.
Zipangizo za HL Cryogenic: Kutsogolera Njira ndi Machitidwe Apamwamba Oyendera Magazi a Nayitrogeni
Kampani ya HL Cryogenic Equipment Co., Ltd yapanga ndikufufuza zaukadaulo wamakono.Dongosolo Loyendera Magazi a Nayitrogeni Yamadzimadzizomwe zimayambira pa thanki yosungiramo zinthu ndikutha ndi zida za MBE. Dongosololi limakwaniritsa ntchito zoyendera nayitrogeni yamadzimadzi, kutulutsa zinthu zodetsa, kuchepetsa kuthamanga ndi malamulo, kutulutsa nayitrogeni, ndi kubwezeretsanso.
