Lisosa tsa Semicera10x10mm Nonpolar M-sefofane sa Aluminium Substratee entsoe ka makhethe ho fihlela litlhoko tse nepahetseng tsa lits'ebetso tse tsoetseng pele tsa optoelectronic. Karoloana ena e na le sebopeho sa sefofane sa M-se sa polar, se bohlokoa bakeng sa ho fokotsa litlamorao tsa polarization ho lisebelisoa tse kang li-LED le li-laser diode, tse lebisang ts'ebetsong le ts'ebetsong e ntlafetseng.
The10x10mm Nonpolar M-sefofane sa Aluminium Substratee entsoe ka boleng bo ikhethang ba kristale, e netefatsang bofokoli bo fokolang le bots'epehi bo phahameng ba sebopeho. Sena se etsa hore e be khetho e nepahetseng bakeng sa kholo ea epitaxial ea lifilimi tsa boleng bo phahameng ba III-nitride, tse bohlokoa bakeng sa nts'etsopele ea lisebelisoa tsa optoelectronic tsa moloko o latelang.
Boenjiniere bo nepahetseng ba Semicera bo netefatsa hore e 'ngoe le e 'ngoe10x10mm Nonpolar M-sefofane sa Aluminium Substratee fana ka botenya bo sa fetoheng le botenya ba bokaholimo, tse bohlokoa bakeng sa ho beoa ha filimi e tšoanang le ho etsa lisebelisoa. Ho feta moo, boholo ba compact ea substrate bo etsa hore e tšoanele libaka tsa lipatlisiso le tsa tlhahiso, e lumellang tšebeliso e bonolo lits'ebetsong tse fapaneng. Ka botsitso ba eona bo botle ba mocheso le lik'hemik'hale, substrate ena e fana ka motheo o tšepahalang bakeng sa nts'etsopele ea mahlale a morao-rao a optoelectronic.
