Tlhaloso e Khutšoanyane:

Gallium nitride (GaN), joalo ka thepa ea silicon carbide (SiC), ke ea moloko oa boraro oa thepa ea semiconductor e nang le bophara ba lekhalo la band, e nang le lekhalo le leholo la sehlopha, conductivity e phahameng ea mocheso, sekhahla se phahameng sa ho falla ha elektronike, le tšimo e phahameng ea motlakase e senyehang. litšobotsi.Lisebelisoa tsa GaN li na le menyetla e mengata ea ts'ebeliso ka makhetlo a mangata, lebelo le phahameng le masimo a tlhokahalo ea matla a phahameng a kang mabone a pholosang matla a LED, pontšo ea laser projection, likoloi tse ncha tsa matla, marang-rang a bohlale, puisano ea 5G.

Thepa ea semiconductor ea moloko oa boraro haholo-holo e kenyelletsa SiC, GaN, daemane, joalo-joalo, hobane bophara ba lekhalo la sehlopha sa eona (Mohlala) bo boholo ho feta kapa bo lekana le li-volts tsa 2.3 electron (eV), tse tsejoang hape e le lisebelisoa tse pharaletseng tsa lekhalo la semiconductor. Ha ho bapisoa le lisebelisoa tsa semiconductor tsa moloko oa pele le oa bobeli, lisebelisoa tsa semiconductor tsa moloko oa boraro li na le melemo ea ho tsamaisa mocheso o phahameng, motlakase o senyehang haholo, tekanyo e phahameng ea ho falla ha elektronike le matla a phahameng a ho kopanya, a ka finyellang litlhoko tse ncha tsa theknoloji ea morao-rao ea elektroniki bakeng sa boemo bo phahameng. mocheso, matla a phahameng, khatello e phahameng, maqhubu a phahameng le ho hanyetsa mahlaseli le maemo a mang a thata. E na le litebello tsa bohlokoa tsa ts'ebeliso maemong a ts'ireletso ea naha, sefofane, sefofane, tlhahlobo ea oli, polokelo ea mahlo, joalo-joalo, 'me e ka fokotsa tahlehelo ea matla ka ho feta 50% liindastering tse ngata tsa maano tse kang likhokahano tsa Broadband, matla a letsatsi, tlhahiso ea likoloi, mabone a semiconductor, le marang-rang a bohlale, 'me a ka fokotsa bophahamo ba thepa ka ho feta 75%, e leng ntho ea bohlokoahali bakeng sa nts'etsopele ea mahlale a batho le thekenoloji.
