N&A no GaN-on-Diamond Wafers
Q1: He aha ka pono o ka hoʻohana ʻana i nā wafers GaN-on-Diamond i nā noi kiʻekiʻe?
A1:Hoʻohui nā wafers GaN-on-Diamond i ka mobility electron kiʻekiʻe a me ka bandgap ākea o GaN me ka conductivity thermal o ke daimana. ʻO kēia ka mea e hiki ai i nā mea hana kiʻekiʻe ke hana i nā pae mana kiʻekiʻe aʻo ka mālama pono ʻana i ka wela, e hōʻoia ana i ka ʻoi aku ka maikaʻi a me ka hilinaʻi e hoʻohālikelike ʻia i nā mea kahiko.
Q2: Hiki ke hoʻopilikino ʻia nā wafers GaN-on-Diamond no ka mana kūikawā a me nā koi alapine?
A2:ʻAe, hāʻawi nā wafers GaN-on-Diamond i nā koho maʻamau, me ka mānoanoa o ka papa epitaxial (0.6 µm a i 2.5 µm), ka nui wafer (4-ʻīniha, 6-ʻīniha), a me nā ʻāpana ʻē aʻe e pili ana i nā pono noi kikoʻī, e hāʻawi ana i ka maʻalahi no nā noi kiʻekiʻe a me nā alapine kiʻekiʻe.
Q3: He aha nā pōmaikaʻi nui o ke daimana ma ke ʻano he substrate no GaN?
A3:ʻO ka hoʻoili wela loa o Diamond (a hiki i 2200 W/m·K) ke kōkua pono i ka hoʻopau ʻana i ka wela i hana ʻia e nā hāmeʻa GaN mana kiʻekiʻe. ʻO kēia mana hoʻokele wela e hiki ai i nā mea hana GaN-on-Diamond ke hana i nā mana kiʻekiʻe a me nā alapine, e hōʻoia i ka hoʻomaikaʻi ʻana i ka hana a me ka lōʻihi.
Q4: Ua kūpono anei nā wafers GaN-on-Diamond no ka lewa a i ʻole nā noi aerospace?
A4:ʻAe, kūpono nā wafers GaN-on-Diamond no ka lewa a me nā noi aerospace ma muli o ko lākou hilinaʻi kiʻekiʻe, nā mana hoʻokele wela, a me ka hana i nā kūlana koʻikoʻi, e like me ka radiation kiʻekiʻe, nā ʻano wela, a me ka hana kiʻekiʻe.
Q5: He aha ke ola i manaʻo ʻia o nā mea hana i hana ʻia mai nā wafers GaN-on-Diamond?
A5:ʻO ka hui pū ʻana o ka paʻa paʻa ʻana o GaN a me nā waiwai hoʻoheheʻe wela o ka daimana e hopena i kahi ola lōʻihi no nā mea hana. Hoʻolālā ʻia nā mea hana ʻo GaN-on-Diamond e hana i nā kaiapuni paʻakikī a me nā kūlana mana kiʻekiʻe me ka liʻiliʻi liʻiliʻi i ka manawa.
Q6: Pehea ka hopena o ka conductivity thermal o daimana i ka hana holoʻokoʻa o nā wafers GaN-on-Diamond?
A6:He kuleana koʻikoʻi ka conductivity thermal thermal o daimana i ka hoʻomaikaʻi ʻana i ka hana o nā wafers GaN-on-Diamond ma o ka lawe pono ʻana i ka wela i hana ʻia i nā noi mana kiʻekiʻe. Mālama kēia i ka mālama ʻana o nā hāmeʻa GaN i ka hana maikaʻi loa, e hōʻemi i ke koʻikoʻi wela, a pale i ka overheating, kahi paʻakikī maʻamau i nā mea semiconductor maʻamau.
Q7: He aha nā noi maʻamau kahi i hoʻokō ai nā wafers GaN-on-Diamond i nā mea semiconductor ʻē aʻe?
A7:ʻOi aku ka maikaʻi o nā wafers GaN-on-Diamond i nā mea ʻē aʻe i nā noi e koi ana i ka mālama ʻana i ka mana kiʻekiʻe, ka hana alapine kiʻekiʻe, a me ka hoʻokele wela maikaʻi. Hoʻopili kēia i nā mea hoʻonui mana RF, nā ʻōnaehana radar, kamaʻilio microwave, kamaʻilio satellite, a me nā mea uila mana kiʻekiʻe.
Ka hopena
Hāʻawi nā wafers GaN-on-Diamond i kahi hopena kūʻokoʻa no nā noi kiʻekiʻe a me nā mana kiʻekiʻe, e hui pū ana i ka hana kiʻekiʻe o GaN me nā waiwai wela o ka daimana. Me nā hiʻohiʻona maʻamau, ua hoʻolālā ʻia lākou e hoʻokō i nā pono o nā ʻoihana e koi ana i ka hāʻawi ʻana i ka mana maikaʻi, ka hoʻokele wela, a me ka hana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hilinaʻi a me ka lōʻihi i nā kaiapuni paʻakikī.
