Inkcazelo emfutshane:

Njengomathiriyeli we-semiconductor yesizukulwana sesithathu, i-gallium nitride ineenzuzo zokumelana nobushushu obuphezulu, ukuhambelana okuphezulu, ukuhanjiswa kwe-thermal ephezulu kunye ne-gap band ebanzi. Ngokwezixhobo ezahlukeneyo ze-substrate, i-gallium nitride epitaxial sheets inokwahlulwa ibe ngamacandelo amane: i-gallium nitride esekelwe kwi-gallium nitride, i-silicon carbide esekelwe kwi-gallium nitride, i-sapphire esekelwe kwi-gallium nitride kunye ne-silicon esekelwe kwi-gallium nitride. I-Silicon-based gallium nitride epitaxial sheet yeyona mveliso isetyenziswa kakhulu enexabiso eliphantsi lokuvelisa kunye nobuchwepheshe bokuvelisa obuvuthiweyo.

Ukusetyenziswa kwephepha le-gallium nitride GaN epitaxial sheet

Ngokusekwe kwintsebenzo ye-gallium nitride, iitshiphusi ze-gallium nitride epitaxial zifaneleka ikakhulu kumandla aphezulu, amaza omoya aphezulu, kunye nokusetyenziswa kwamandla ombane aphantsi.

Ibonakaliswa kwi:

I-1) I-bandgap ephezulu: I-bandgap ephezulu iphucula umgangatho wombane wezixhobo ze-gallium nitride kwaye inokuvelisa amandla aphezulu kunezixhobo ze-gallium arsenide, ezilungele ngokukodwa izikhululo zesiseko sonxibelelwano lwe-5G, i-radar yempi kunye nezinye iindawo;

I-2) Ukusebenza okuphezulu kokuguqulwa: ukuchasana kwe-gallium nitride yokutshintsha izixhobo ze-elektroniki zi-3 ii-odolo zobukhulu obuphantsi kunezixhobo ze-silicon, ezinokunciphisa kakhulu ilahleko ekutshintsheni;

3) I-conductivity ephezulu ye-thermal: i-conductivity ephezulu ye-thermal ye-gallium nitride yenza ukuba ibe nentsebenzo ebalaseleyo yokutshatyalaliswa kobushushu, ilungele ukuveliswa kwamandla aphezulu, ubushushu obuphezulu kunye nezinye iindawo zezixhobo;

4) Ukuqhekeka kwamandla entsimi yombane: Nangona amandla ombane ophukileyo we-gallium nitride esondele kuleyo ye-silicon nitride, ngenxa yenkqubo ye-semiconductor, ukungahambelani kwe-lattice yezinto kunye nezinye izinto, ukunyamezela kwamandla ombane wezixhobo ze-gallium nitride zihlala zimalunga ne-1000V, kwaye Usetyenziso olukhuselekileyo lombane ludla ngokuba ngaphantsi kwe-650V.
