Mai ka silicon a i ka Ga₂O₃, hōʻike ka ulu ʻana o ka semiconductor i ka lanakila o ke kanaka ma luna o nā palena kino. Aia ka manawa kūpono o Kina i ka hoʻokele ʻana i nā mea o ka hanauna ʻehā me ka hoʻomaka ʻana i nā hana hou o ka hanauna ʻelima. E like me ka ʻōlelo a Academician Yang Deren: "Pono ka hana hou maoli i ka hoʻokumu ʻana i nā ala i hele ʻole ʻia." ʻO ka synergy o ke kulekele, ke kapikala, a me ka ʻenehana e hoʻoholo i ka hopena semiconductor o Kina.
Ua kū mai ʻo XKH ma ke ʻano he mea hoʻolako hoʻonā i hoʻohui ʻia i ka ʻaoʻao kū pololei e loea ana i nā mea semiconductor holomua ma nā hanauna ʻenehana he nui. Me nā mākaukau koʻikoʻi e pili ana i ka ulu ʻana o ke kristal, ka hana pololei, a me nā ʻenehana uhi hana, hāʻawi ʻo XKH i nā substrates hana kiʻekiʻe a me nā wafers epitaxial no nā noi ʻoi loa i nā uila mana, nā kamaʻilio RF, a me nā ʻōnaehana optoelectronic. Hoʻopuni kā mākou ʻōnaehana hana i nā kaʻina hana ponoʻī no ka hana ʻana i nā wafers silicon carbide a me gallium nitride 4-8 iniha me ka kaohi kīnā alakaʻi ʻoihana, me ka mālama ʻana i nā papahana R&D ikaika i nā mea bandgap ākea ākea e pili ana i ka gallium oxide a me nā semiconductors daimana. Ma o nā hui pū ʻana me nā ʻoihana noiʻi alakaʻi a me nā mea hana lako, ua hoʻomohala ʻo XKH i kahi kahua hana maʻalahi e hiki ke kākoʻo i ka hana nui o nā huahana maʻamau a me ka hoʻomohala kūikawā o nā hoʻonā mea i hana ʻia. Ke nānā nei ka ʻike loea o XKH i ka hoʻoponopono ʻana i nā pilikia koʻikoʻi o ka ʻoihana e like me ka hoʻomaikaʻi ʻana i ka like ʻana o ka wafer no nā mea mana, ka hoʻomaikaʻi ʻana i ka hoʻokele wela i nā noi RF, a me ka hoʻomohala ʻana i nā heterostructures hou no nā mea photonic hanauna e hiki mai ana. Ma ka hoʻohui ʻana i ka ʻepekema mea holomua me nā hiki ʻenekinia kikoʻī, hiki iā XKH i nā mea kūʻai aku ke lanakila i nā palena hana ma nā noi alapine kiʻekiʻe, mana kiʻekiʻe, a me nā ʻano kaiapuni koʻikoʻi me ke kākoʻo ʻana i ka hoʻololi ʻana o ka ʻoihana semiconductor kūloko i ke kūʻokoʻa kaulahao lako nui aʻe.
Eia nā mea aʻe o ka wafer sapphire 12 iniha a me ka substrate SiC 12 iniha a XKH:
