6. He pai te mahi wera: He pai te kawe wera o te rauemi GaAs, e āwhina ana ki te whakaiti i te pāmahana mahi o te taiaho me te whakapai ake i te pumau.
7. Whānui te whakarerekētanga: Ka taea te whakarite i te mana putanga mā te whakarerekē i te iahiko puku kia urutau ki ngā whakaritenga tono rerekē.

Ko ngā whakamahinga matua o ngā papa epitaxial taiaho GaAs ko:

1. Whakawhitiwhiti muka whatu: Ka taea te whakamahi i te rau epitaxial taiaho GaAs hei hanga taiaho i roto i te whakawhitiwhiti muka whatu hei whakatutuki i te tuku tohu whatu tere-teitei me te tawhiti-roa.

2. Ngā tono ahumahi: I roto i te mara ahumahi, ka taea te whakamahi i ngā rau epitaxial taiaho GaAs mō te whakatere taiaho, te tohu taiaho me ētahi atu tono.

3. VCSEL: Ko te taiaho whakaputa mata kōhao poutū (VCSEL) he mara tono nui o te rau epitaxial taiaho GaAs, e whakamahia whānuitia ana i roto i te whakawhitiwhiti whatu, te rokiroki whatu me te pūoko whatu.

4. Te mara whero me te mara ira: Ka taea hoki te whakamahi i te rau epitaxial taiaho GaAs ki te hanga taiaho whero, ngā whakaputa ira me ētahi atu taputapu, e whai wāhi nui ana ki te kimi ira whero, te whakaatu mārama me ētahi atu mara.

Ko te whakarite i te rau epitaxial taiaho GaAs e whakawhirinaki ana ki te hangarau tipu epitaxial, tae atu ki te whakapūtanga kohu matū whakarewa-organika (MOCVD), te epitaxial hihi ngota (MBE) me ētahi atu tikanga. Ka taea e ēnei tikanga te whakahaere tika i te matotoru, te hanganga me te hanganga tioata o te paparanga epitaxial hei whiwhi rau epitaxial taiaho GaAs kounga teitei.

Ka tukuna e XKH ngā whakaritenga o ngā rau epitaxial GaAs i roto i ngā hanganga me ngā matotoru rerekē, e kapi ana i te whānuitanga o ngā tono i roto i ngā whakawhitiwhitinga whatu, VCSEL, infrared me ngā mara ira mārama. He mea hanga ngā hua a XKH me ngā taputapu MOCVD matatau hei whakarite i te mahi teitei me te pono. Mō ngā mahi kawe, he whānuitanga o ngā hongere pūtake o te ao a XKH, ka taea te whakahaere ngāwari i te maha o ngā ota, me te whakarato ratonga uara-tāpiri pēnei i te whakapai ake me te wehewehe. Mā ngā tukanga tuku whai hua ka whakarite i te tukunga i te wā tika me te whakatutuki i ngā whakaritenga a te kiritaki mō te kounga me ngā wā tuku.
