Electricity Engineering Department Holds Seminar
Within the scientific and cultural activities of the first semester of the Electricity Engineering Department for the academic year 2017-2018, Lect.Dr.Mahmed Jumaa presented a lecture " Introduction to Molecular Beam Epitaxy)) at Dijlah Hall in the presence of the head of the department Assc.Prof.Dr.Dari Yousif and both scientific and administrative deputies and all the faculty.
The seminar dealt with MBE, which is a device used to make semiconductors from detectors, transistors and solar cells. The device consists of three main rooms, the loading room. Conservation room and building room and has very high build ability with pure materials of silicon, zinc, gallium ... etc. The device can be built with ten atomic layers per second with the possibility of watching the construction process directly. The device needs high requirements including continuous uninterrupted feeding and continuous cooling of liquid nitrogen, as well as high purity semiconductor materials that are loaded into the construction cells of the device.
At the end of the seminar, the discussion was opened and the questions and inquiries were answered
