Graphite tse tharo-petal cruciblebakeng sa kholo ea kristale ea semiconductor: E entsoe ka lisebelisoa tse tala tse phahameng haholo 'me e entsoe ka theknoloji e nepahetseng, e na le khanyetso e ntle ea mocheso o phahameng, ho hanyetsa kutu, le conductivity ea mocheso. Nakong ea tšebeliso ea mocheso o phahameng, coefficient ea ho atolosa mocheso e nyenyane, 'me e na le khanyetso e itseng ea ho thibela ho futhumala ka potlako le ho pholile. E na le khanyetso e matla ea kutu ho litharollo tsa acid le alkaline le botsitso bo botle ba lik'hemik'hale.

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. Sekhabiso sena se hahelletsoeng se eketsa khanyetso ea bona tikolohong e thata ea lik'hemik'hale, e ba etsa khetho ea mantlha bakeng sa tlhahiso ea semiconductor.
Ho fihlela litlhoko tse boima tsa indasteri ea semiconductor bakeng sa kholo e nepahetseng ea kristale, re sebelisitse mekhoa e tsoetseng pele ea thepa ho netefatsa horeGraphite tse tharo-petal cruciblee sebetsa hantle maemong a fapaneng. Sehlahisoa sena ha se na feela lebitso la lets'oao la semicera, empa hape se bonts'a boitlamo ba rona ho ntlafatso ea theknoloji le boleng bo holimo.
