E like me kā kākou e ʻike nei, ʻo ka wehewehe ʻana o ka semiconductor ʻo ia ka conductivity ma waena o nā conductors maloʻo a me nā insulators, resistivity ma waena o ka metala a me ka insulator, ʻo ia hoʻi ma ka mahana o ka lumi i loko o ka pae o 1mΩ-cm ~ 1GΩ-cm. I nā makahiki i hala iho nei, ua ʻike ʻia ke kiʻekiʻe o ke kūlana o ka uhi semiconductor vacuum i nā ʻoihana semiconductor nui, ʻoi aku hoʻi i kekahi mau ʻano noiʻi ʻenehana hoʻomohala ʻōnaehana hoʻohui nui i nā mea hoʻololi magnetoelectric, nā mea hoʻomālamalama a me nā hana hoʻomohala ʻē aʻe. He kuleana koʻikoʻi ko ka uhi semiconductor vacuum.
Hoʻohālikelike ʻia nā semiconductors e ko lākou ʻano kūloko, ka mahana a me ka nui o ka haumia. Hoʻokaʻawale ʻia nā mea uhi semiconductor vacuum mai kekahi i kekahi ma o nā hui i hoʻohui ʻia. Ma ke ʻano he kumu o nā mea āpau, ua hoʻokumu ʻia lākou ma luna o ka boron, carbon, silicon, germanium, arsenic, antimony, tellurium, iodine, a me nā mea ʻē aʻe, a me kekahi mau GaP, GaAs, lnSb, a me nā mea ʻē aʻe. Aia kekahi mau semiconductors oxide, e like me FeO, Fe₂O₃, MnO, Cr₂O₃, Cu₂O, a me nā mea ʻē aʻe.
ʻO ka hoʻoheheʻe ʻana o ka vacuum, ka uhi ʻana i ka sputtering, ka uhi ʻana ion a me nā lako ʻē aʻe e hiki ke hana i ka uhi semiconductor vacuum. He ʻokoʻa kēia mau lako uhi i kā lākou ʻano hana, akā hana lākou a pau i ka mea uhi semiconductor i waiho ʻia ma luna o ka substrate, a ma ke ʻano he mea o ka substrate, ʻaʻohe koi, hiki ke semiconductor a ʻaʻole paha. Eia kekahi, hiki ke hoʻomākaukau ʻia nā uhi me nā waiwai uila a me nā ʻano optical like ʻole ma o ka hoʻolaha ʻana o ka haumia a me ka hoʻokomo ʻana o ka ion ma luna o ka substrate semiconductor ma kahi laulā. Hiki ke hana ʻia ka papa lahilahi hopena ma ke ʻano he uhi semiconductor ma ke ʻano laulā.
He mea nui ka uhi semiconductor vacuum i nā mea uila inā no nā mea hana a passive paha. Me ka holomua mau o ka ʻenehana uhi semiconductor vacuum, ua hiki ke kaohi pololei i ka hana kiʻiʻoniʻoni.
I nā makahiki i hala iho nei, ua holomua wikiwiki ka uhi ʻana o ka amorphous a me ka uhi ʻana o ka polycrystalline i ka hana ʻana i nā mea hana photoconductive, nā paipu hopena kahua i uhi ʻia, a me nā cell solar kiʻekiʻe. Eia kekahi, ma muli o ka hoʻomohala ʻana o ka uhi semiconductor vacuum a me ka ʻili lahilahi o nā sensor, kahi e hōʻemi nui ai i ka paʻakikī o ke koho ʻana i nā mea a hoʻomaʻalahi i ke kaʻina hana. Ua lilo nā lako uhi semiconductor vacuum i mea pono no nā noi semiconductor. Hoʻohana nui ʻia nā lako no ka uhi semiconductor o nā mea kāmela, nā cell solar, nā transistors i uhi ʻia, ka hoʻokuʻu ʻana o ke kahua, ka mālamalama cathode, ka hoʻokuʻu ʻana o ka electron, nā mea ʻike kiʻi lahilahi, a pēlā aku.
Ua hoʻolālā ʻia ka laina uhi magnetron sputtering me kahi ʻōnaehana hoʻokele piha piha, kahi interface kanaka-mīkini maʻalahi a maʻalahi hoʻi. Ua hoʻolālā ʻia ka laina me kahi papa hana piha e hoʻokō i ka nānā piha ʻana i ke kūlana hana no nā ʻāpana laina hana holoʻokoʻa, ka hoʻonohonoho ʻana i nā palena hana, ka pale hana a me nā hana alarm. Palekana, hilinaʻi a paʻa ka ʻōnaehana hoʻokele uila holoʻokoʻa. Hoʻolako ʻia me ka pahuhopu magnetron sputtering ʻaoʻao ʻelua o luna a me lalo a i ʻole ka ʻōnaehana uhi ʻaoʻao hoʻokahi.
Hoʻohana nui ʻia nā lako i nā papa kaapuni seramika, nā capacitors voltage kiʻekiʻe chip a me nā uhi substrate ʻē aʻe, ʻo nā wahi noi nui he mau papa kaapuni uila.
