Graphite three-petal crucible for semiconductor crystal kholo e Featured Image

Tlhaloso e Khutšoanyane:

Semicera's graphite three-lobed crucibles for semiconductor crystal crystal e etselitsoe ho sebelisoa ka ho fetisisa tlhokahalo ea semiconductor. Li-crucible tsa rona li na le likarolo tse tsoetseng pele tsa graphite tsa isostatic, tse netefatsang ts'ebetso e ikhethang ea mocheso o phahameng le ho hanyetsa ho hoholo ha kutu. Moqapi o ikhethang oa li-lobed tse tharo o ntlafatsa conductivity ea mocheso bakeng sa kholo ea kristale e tšoanang le liphello tse ntle. Re labalabela ho ba molekane oa hau oa nako e telele Chaena.

Ho semicera, re etelletsa boleng le boqapi pele. Li-crucible tsa rona li koahetsoeCVD SiC, e leng ho eketsang nako e telele le nako ea bophelo ea bona.
