No ke aha e hoʻohana ai nā chips (a i ʻole nā mea hana uila) i nā semiconductor ma mua o nā conductors?
Ua lilo nā Semiconductor i mea koʻikoʻi o ke ola a ʻo kā lākou hoʻohana ʻana i nā wahi āpau.Inā ʻaʻohe semiconductors, ʻaʻohe lekiō, ʻaʻohe kamepiula, ʻaʻohe kelepona paʻa, ʻaʻohe TV, ʻaʻohe mīkini holoi, ʻaʻohe pāʻani wikiō, a ʻoiaʻiʻo ʻaʻohe paʻi 3D, autonomous driving, lāʻau akamai, a i ʻole photovoltaics.ʻO ka hoʻomohala wikiwiki ʻana o ka Pūnaewele o nā mea i hana i nā semiconductor i ʻoi aku ka maʻalahi.
ʻOiai ka hilinaʻi ʻana i ka ʻenehana pahu hau (nā paipu uila, ʻike ʻia hoʻi ʻo nā paipu electron, ua hoʻololi ʻia e nā semiconductors no ke kumu o ke kumu kūʻai kiʻekiʻe, ka lōʻihi ʻole, ka nui, a me ka haʻahaʻa haʻahaʻa, me nā electrodes a me nā filament i loko o ka conductive), ua nui nā mea uila. hana ʻia.Ke nānā aku nei i nā lā o ka paipu māmā, nā kīwī, nā phonographs, a me nā lekiō, ua loaʻa nā ʻōpuni ʻōpuʻu maloʻo e koi ana i kekahi mau minuke o ka hoʻomaʻamaʻa i kēlā me kēia manawa e hoʻā ʻia ai a paʻa loa.I loko o nā makahiki he 60 i hala iho nei, ua ʻae ka ʻenehana semiconductor i nā mea hana e lilo i mea wikiwiki, liʻiliʻi, a paʻa.
No laila, no ke aha e hoʻohana ai i nā semiconductors e hana i kēia mau mea uila, ma mua o nā conductors?
He aha nā semiconductors?ʻO ka semiconductor kahi mea e hoʻolele ai i ka uila ma waena o kahi conductor (maʻamau he metala) a me kahi insulator (ka hapa nui he keramika).Hiki i nā semiconductors ke lilo i mau mea maʻemaʻe (silicona a i ʻole germanium) a i ʻole pūhui (gallium arsenide a i ʻole cadmium selenide).I ke kaʻina hana o ka doping, ua hoʻohui ʻia ka liʻiliʻi o nā mea haumia i ka semiconductor maʻemaʻe, e hopena i kahi loli nui i ka conductivity uila o ka mea.
Hana ʻia ka hapa nui o nā mea uila ma muli o nā transistors, a laila e hana i nā hana e like me ka amplification, oscillators, a me arithmetic, i hana ʻia e nā semiconductors.
No ke aha he semiconductors a ʻaʻole nā mea hoʻokele?
No ka mea he nui nā conductivities o nā semiconductors, he mau conductivities kiʻekiʻe wale nō nā conductors, ʻaʻole koi mau i ke ola o kēlā me kēia lā.Me nā semiconductors a me ka doping kūpono, hiki ke hoʻololi i ka conductivity e like me nā koi.I ka manawa like, ʻaʻole hiki ke hoʻopaʻa ʻia i nā conductors, ʻo ke ʻano hiki ʻole ke hoʻokō i ka mea e pono ai (e noʻonoʻo ʻoe he nui nā mea lawe ukana a he liʻiliʻi ka hopena o ka doping).
I ka manaʻo ʻana ua hoʻopili ʻia nā kiko A a me B ma kahi kaapuni e kahi mea hoʻokele, e loaʻa ka volta ma waena o lāua a e kahe ke au ma waena o nā kiko ʻelua;ʻaʻohe ala e hoʻomalu ai i ke kahe o ke au ma ʻaneʻi.ʻO ka mea ʻē aʻe, inā hoʻopili ʻia nā kiko A a me B e kahi insulator, ʻaʻole e kahe ke au a he liʻiliʻi nā mea hiki ke hana e hiki ai ke kahe o ke au (koe ke hoʻonui ʻia ka volta i kahi pae hiki ʻole ke noʻonoʻo).
Eia nō naʻe, inā hoʻohana ʻia kahi transistor ma waena o nā kiko A a me B, hāʻawi ia i kahi ala ikaika no ka hoʻokele ʻana i kēia manawa.Noho ka transistor ma waena o nā kiko A a me B, me ka hoʻohui ʻana i kahi kikoʻī hou C i mea e hoʻopili ai i ka ʻokoʻa uila ma waena o nā helu C a me B e hoʻomaka ai ke kahe ʻana ma waena o A a me B. Hiki ke hana ʻia kēia mau mea ma nā volta haʻahaʻa loa (ma lalo o 5 volts. ) a me nā au haʻahaʻa (ka hoʻohana mana haʻahaʻa).ʻAʻole hiki ke hoʻohana i nā conductors a i ʻole insulators wale nō.No ka mea e alakaʻi mau ana nā conductors, ʻaʻole e alakaʻi nā insulators a ʻo nā semiconductor wale nō e hoʻokō i ka wehe a me ka pani ʻana.
Me ka noʻonoʻo ʻole i nā mea pāʻani koʻikoʻi (e ʻōlelo kekahi e koho i kahi keiki tiger), koho ka hapa nui o ka poʻe i kahi pōpoki.No nā mea pāʻani koʻikoʻi, e koho anei ʻoe i kahi tiger nui?ʻO ke kumu maopopo: ʻaʻole hiki ke hoʻopaʻa ʻia a huhū.Ua like loa ia me ka conductor a me ka semiconductor.
Tiger = conductor (ʻaʻohe mana o ka conductivity)
Cat = semiconductor (hiki ke mālama ʻia ka conductivity e ka doping)
He paʻakikī ka honua o ka ʻepekema a ʻaʻole mau ka ʻenehana i hoʻopaʻa ʻole ʻia.
