Ko te taputapu hiko haurua te uho o ngā taputapu mīhini ahumahi hou, e whakamahia whānuitia ana i roto i ngā rorohiko, ngā hiko kaihoko, ngā whakawhitiwhitinga whatunga, ngā hiko motuka, me ētahi atu wāhanga matua, ko te umanga hiko haurua te nuinga o te tito o ngā wāhanga matua e whā: ngā ara iahiko whakauru, ngā taputapu hiko optoelectronic, ngā taputapu motuhake, me ngā pūoko, e neke atu ana i te 80% o ngā ara iahiko whakauru, ā, he maha ngā wā ka rite te hiko haurua me te ara iahiko whakauru.
E ai ki te kāwai hua, e whā ngā wāhanga matua o te ara iahiko whakauru: te tukatuka iti, te mahara, ngā taputapu arorau, me ngā wāhanga whakatauira. Heoi, nā te whānui haere tonu o te mara tono o ngā taputapu haurua-ira, he maha ngā wā motuhake e hiahiatia ana kia taea e ngā haurua-ira te piri ki te pāmahana teitei, te irahiko kaha, te mana teitei me ētahi atu taiao, kia kore ai e pakaru. Kāore he mana o te whakatupuranga tuatahi me te tuarua o ngā rauemi haurua-ira, nō reira i puta mai ai te whakatupuranga tuatoru o ngā rauemi haurua-ira.
I tēnei wā, ko ngā rauemi haurua whakawhiti whānui āputa e tohuhia ana ekarāhe siliconKo te (SiC), te gallium nitride (GaN), te konutea waikura (ZnO), te taimana, te konumohe nitride (AlN) kei te mākete matua me ngā painga nui ake, e kiia ana ko ngā rauemi semiconductor o te whakatupuranga tuatoru. Ko te whakatupuranga tuatoru o ngā rauemi semiconductor me te whānui o te āputa roopu, ko te teitei ake o te papa hiko pakaru, te kawe wera, te tere kukū hiko me te kaha ake ki te ātete i te irahiko, he pai ake mō te hanga pāmahana teitei, auau teitei, ātete ki te irahiko me ngā taputapu mana teitei, e mōhiotia ana ko ngā rauemi semiconductor whānui āputa roopu (ko te whānui roopu aukati he nui ake i te 2.2 eV), e kiia ana hoki ko ngā rauemi semiconductor pāmahana teitei. Mai i ngā rangahau o nāianei mō ngā rauemi me ngā taputapu semiconductor o te whakatupuranga tuatoru, kua pakari ake ngā rauemi semiconductor silicon carbide me te gallium nitride, ā,hangarau karawiti siliconkoinei te mea tino pakari, engari kei te wāhanga tuatahi tonu te rangahau mō te konutea waikura, te taimana, te konumohe nitride me ētahi atu rauemi.
Ngā Rauemi me ō rātou Āhuatanga：
Karāhe siliconKei te whakamahia whānuitia te rauemi i roto i ngā peera pōro uku, ngā takirere, ngā rauemi semiconductor, ngā gyros, ngā taputapu ine, te rererangi me ētahi atu mara, kua waiho hei rauemi whakakapinga i roto i te maha o ngā mara ahumahi.
He momo whāriki taiao te SiC, he momo momo rite tonu. Neke atu i te 200 ngā whānau momo rite (e mōhiotia ana i tēnei wā) nā te rerekētanga o te raupapa tākai i waenga i ngā paparanga Si me C rua, ka hua ake he hanganga tioata rerekē. Nō reira, he tino pai te SiC mō te whakatupuranga hou o ngā rauemi papaaho rama-whakaputa rama (LED), arā, ngā rauemi hiko mana-teitei.
| āhuatanga | |
| āhuatanga ā-tinana | Te pakeketanga teitei (3000kg/mm), ka taea te tapahi i te rupi |
| He ātete nui ki te kakahu, tuarua ki te taimana anake | |
| E 3 ngā wā teitei ake te kawe wera i tō te Si, ā, e 8~10 ngā wā teitei ake i tō te GaAs. | |
| He teitei te pumau wera o te SiC, ā, kāore e taea te rewa i te pēhanga hauātea. | |
| He mea tino nui te pai o te tohatoha wera mō ngā taputapu mana nui | |
|
āhuatanga matū | He tino kaha te ātete ki te waikura, ātete ki te nuinga o ngā matū waikura e mōhiotia ana i te pāmahana rūma |
| Ka ngāwari te waikura o te mata SiC hei hanga i te SiO, he paparanga angiangi, ka taea te aukati i tōna waikura anō, i roto i I runga ake i te 1700℃, ka rewa te kiriata waikura, ā, ka tere te waikura. | |
| Ko te āputa o te 4H-SIC me te 6H-SIC e toru ngā wā te nui ake i te Si, ā, e rua ngā wā te nui ake i te GaAs: He nui ake te kaha o te papa hiko pakaru i te Si, ā, kua kī te tere o te nekenekehanga irahiko. E rua me te hawhe ngā wā o te Si. He whānui ake te āputa o te 4H-SIC i tō te 6H-SIC |
