Nāianei Electric i roto i te Semiconductors

nāianei Electric i roto i Semiconductors - whakahaua te kaupapa o rua me ngā irahiko, e kua awe e te mara hiko.

Ka rite ki te hua o ngā, i kitea ai e kore te te nāianei hiko i roto i Semiconductors tahi e te whakawhitinga o te mea - e kore ratou e whai wāhi i tetahi huringa matū. Ko te kupu, nga kawe, e taea te whakaaro irahiko i roto i Semiconductors.

Ka taea te whakaritea te kaha o te rauemi ki te hanga i roto i reira i te nāianei hiko i te kawe ia motuhake. E tenei tohu conductors noho he tūranga takawaenga i waenganui i nga conductors me insulators. Semiconductors - he momo rerekē o ngā kohuke, etahi konganuku, sulfides whakarewa, me ētahi atu enei nāianei Electric i roto i Semiconductors whakatika i te kukū o te irahiko noa e taea te neke directionally i roto i te taonga. Te whakatairite konganuku me conductors, kia tuhia te reira e te vai nei te rerekētanga i waenganui i te mana pāmahana i runga i to ratou kawe ia. He hua i roto i te pāmahana arata'i ki te hekenga i roto i te kawe ia o konganuku. I roto i Semiconductors nga piki auau kawenga. Ki te he pāmahana hua Semiconductor, ka waiho atu Horehore te nekehanga o ngā irahiko free. Ko te tika ki te hua i roto i te maha o collisions tenei. Heoi, i roto i Semiconductors i rite ki ngā konganuku, te reira te nui nui haere whakaatu kiato o irahiko free. Enei āhuatanga i te pānga ritenga i runga i te kawe ia: te atu collisions, te iti te kawe ia, te nui te kukū, te teitei ko reira. I roto i te konganuku, kahore he fakafalala i waenganui i te pāmahana me te kukū o ngā irahiko noa, kia e te tauiraa i roto i te kawe ia ki te whakanui ake te pāmahana heke anake te taea o te nekehanga whakahau o irahiko free. Ko te Semiconductor, te pānga whakaatu o te whakanui ake i te kukū teitei. Ko te kupu, ka waiho nui, te nui te kawe ia te pāmahana ara.

He he he hononga i waenganui i te kaupapa o kawe tiaki me te wā pērā i nāianei hiko i roto i Semiconductors. I roto i te Semiconductors, atu tenei kawe āhuatanga e te ahua o ngā āhuatanga, i roto i nei e tino pāmahana me te viivii ore o te rauemi. E wehea Semiconductors te viivii ki, ēhara, me te ake.

Ka rite ki hoki ona ake kaiwhakahaere, e kore ai e faufaa mo ratou te pānga o poke i te tetahi pāmahana. Mai te mea iti, i roto i te Semiconductor tūturu te āputa ropu o Semiconductors, ina tae te pāmahana kore pū, i reira te mea he whakakī oti o nga irahiko honohono. Ko Ko tino noa te pēne āriponga: kahore he kawe ia hiko, me ngā mahi reira hei insulator pai. I te tahi atu pāmahana, i reira ko te pea e taea te rerekē waiariki o te irahiko motuhake hinga te arai pea me puta i roto i te pēne kawenga.

pānga Thomson

Ko te parau tumu o te pānga Thomson thermoelectric ina e te nāianei hiko i roto i Semiconductors, haere nei i reira ko te rōnaki pāmahana i roto i a ratou, ki te kahore tuku wera joule absorption o atu moni o te wera ranei anoo i runga i te aronga i roto i nei e rere nāianei.

kākahu iti tauira whakawera, he hanganga ōrite pānga ona āhuatanga, ai riro te rauemi kākahu-kore. Ko te kupu, ko te pānga Thomson ko te āhuatanga motuhake Peltier. Ko te rerekētanga anake ko e te ngā hanganga matū-kore o te tauira, me te pāmahana o te taketake ko tenei heterogeneity.
