Ngā āhuatanga hiko me ngā tono o ngā kiriata taimana
He whānui te whānuitanga o te taimana, he nui te nekehanga kawe, he pai te kawe wera, he tere teitei te nekehanga irahiko, he iti te pūmau dielectric, he nui te ngaohiko pakaru me te nekehanga kōhao irahiko, me ētahi atu. E rua ngā whakarea teitei ake o tōna ngaohiko pakaru i tērā o Si me GaAs, ā, he nui ake te kaha o tōna nekehanga irahiko me te kōhao i tērā o te silicon monocrystalline CA:. Ka taea te whakamahi i te kiriata taimana hei rauemi semiconductor whānui. I tēnei wā kua angitu te rangahau i te taha o te taimana ki te whai i te silicon (te tinana hua pānga me te ara iahiko arorau), ka taea e ēnei taputapu te mahi i raro i te mahi noa i te 600 ℃, he nui te tono i roto i te taputapu semiconductor pāmahana teitei. Nā te whānui o te āputa roopu o te taimana, ka taea te whakamahi mō te tuku mārama kikorangi, te kite mārama ultraviolet, me ngā taputapu turuturu iti.
Ngā Āhuatanga Whatu me ngā Whakamahinga o ngā Kiriata Angiangi Taimana
He tino pai ngā āhuatanga whatu o te taimana, me te noho o ngā tihi mimiti iti (nā te wiri phonon) i roto i te 3 ~ 5μm, mai i waho (225nm) ki te infrared tawhiti (25μm) te whānuitanga katoa o ngā roopu, he nui te whakawhiti o te taimana, he rauemi matapihi pai mō ngā taiaho infrared kaha-teitei me ngā pūoko. Ko te taimana i roto i te roopu infrared o te mārama whatu, ka waiho hei rauemi whakaputa tiketike-kiato, ātete-waikura e utaina ana e te matapihi whatu o waho e kiia ana ko te rauemi pai, ka taea te whakamahi mō te hopu pere i te matapihi infrared e kiia ana. Hei tāpiri, he teitei te taupū whakaata o te taimana, ka taea te whakamahi hei kiriata whakaata whakaiti pākahiko o te rā. Kāore e ngāwari te whakapohehe i te kiriata taimana mo te urunga o te ngaru radar, ka taea te whakamahi hei radome, hei rere me ngā pere i roto i te rerenga supersonic, kāore e taea e te radar upoko te tu atu i te pāmahana teitei, he uaua ki te tu atu i ngā pata ua tere me te takahi puehu. He taimana te hanga o te radome, ehara i te mea he tere te horapa o te wera, he pai hoki te ātete ki te kakahu, engari ka taea hoki te whakaoti i te raruraru hanumi pāmahana teitei i te rere tere.
Ētahi atu whakamahinga o te kiriata taimana
He teitei te modulus Young me te modulus elastic o te kiriata Diamond, e āwhina ana i te tuku ngaru oro auau teitei me te pono teitei, ā, he momo rauemi hou mō te hanga tātari ngaru oro mata tino tairongo. He teitei te modulus o te elasticity o te Diamond me te tere horapa oro teitei, ā, ka taea te whakamahi hei kaikorero pono teitei mō te oro kounga teitei.
He teitei te ngāwari o te taimana, ā, he tere hoki te horapa o te oro, nō reira ka taea te whakamahi hei rauemi kiriuhi wiri mō te pūoro pono o te oro kounga teitei.
Hei tāpiritanga, he pai te pumau matū o te taimana, ā, he ātete ki te waikura i ngā waikawa kore-waikura i ngā pāmahana rerekē. Ko tōna wāhanga matua, ko te waro, he rauemi kore-paitini, kore-whakapoke e kore e tauhohe ki te tinana tangata. Nā te mea kāore te taimana e tauhohe ki te toto tangata me ētahi atu wai kiko, he rauemi pai hoki te taimana hei whakauru koiora hauora, ka taea te whakamahi hei hanga i ngā takirere ngākau horihori.
