Kutaya Nthunzi ya Zachilengedwe mu Chitsulo

Kuyika mpweya wa organic chemical vapor deposition (MOCVD), komwe kumachokera mpweya wa organic compound gas, ndipo njira yoyambira yoyika mpweya ndi yofanana ndi CVD.

1.MOCVD mpweya wosaphika

Gwero la mpweya lomwe limagwiritsidwa ntchito pa MOCVD ndi mpweya wa metal-organic compound (MOC). Ma metal-organic compounds ndi mankhwala okhazikika omwe amapangidwa pophatikiza zinthu zachilengedwe ndi zitsulo. Ma organic compounds ali ndi alkyl, aromatic. Alkyl imaphatikizapo methyl, ethyl, propyl, ndi butyl. Alkyl imaphatikizapo methyl, ethyl, propyl, ndi butyl. Mafuta onunkhira kuphatikiza phenyl homologues, trimethyl gallium, [Ga(CH2)₃)₃], trimethyl aluminiyamu [Al(CH2₃)₃] kuti aike ma microelectronics, optoelectronics, semiconductors mu ma compounds atatu, asanu mu filimu, monga Ga(CH2)₃)₃ ndipo ammonia ikhoza kukhala mu silicon wafer kapena safiro pa kukula kwa epitaxial kwa nyali za LED mu InGaN luminescent layer. Nyali za LED zimapulumutsa mphamvu kuposa nyali za tungsten incandescent 90%, zopulumutsa mphamvu zoposa 60%. Nyali za LED zimapulumutsa mphamvu ndi 90% kuposa nyali za tungsten incandescent ndipo zopulumutsa mphamvu ndi 60% kuposa nyali za fluorescent. Masiku ano, mitundu yonse ya nyali za pamsewu, nyali zowunikira ndi nyali zamagalimoto zimagwiritsa ntchito mafilimu otulutsa kuwala kwa LED opangidwa ndi MOCVD.

2. Kutentha kwa malo osungira

Kutentha kwa zinthu zopangidwa ndi zitsulo zachilengedwe kumakhala kotsika, ndipo kutentha kwa zinthu zomwe zasungidwa ndi kotsika kuposa kwa HCVD. Kutentha kwa zinthu zomwe zasungidwa ndi MOCVD kumatha kuchepetsedwa kufika pa madigiri 500.
