Semiconductors - Ukuqokwa kanye ngezigaba

amathuluzi Digital hlala indima ebaluleke ngokwengeziwe ku electronics yesimanje. Amadivayisi ukusebenzisa ku chips manje lwangena cishe zonke izicelo - imishini kamasipala nezezimboni, amathoyizi, ividiyo, umsakazo-TV uchwepheshe nokunye. Nokho, zikhona namanje Ububanzi izakhi analog leyehlukene. Ngaphezu kwalokho, amadivaysi Semiconductor - uqobo chips yesimanje.

Kanjani kumadivayisi ezifana? Isisekelo amadivayisi njenge Semiconductor izidakamizwa kukhona Semiconductors. Ngokusho izici zayo kagesi kanye izakhiwo lilinganise phakathi insulators nama babashayeli. Izici ezilihlukanisayo ka - a ukwencika conductivity phezu ezingeni lokushisa elifanele, izimfanelo imithelela ionizing emisebeni nokukhanya, futhi emakamu ukungcola konke ngokuhuheka. Semiconductors cishe isethi efanayo izici.

Ngo inqubo yokudala i kagesi kunoma iyiphi ikhemikhali bayakwazi ukubamba iqhaza eselula kuphela icala zenethiwekhi. Lapho icala mobile abathwali per unit ivolumu yento engesimumathini, aba maningi conductivity kagesi. Ngo izinsimbi cishe zonke electron amahhala, futhi lokhu kuholela ekuphelelweni conductivity zabo eziphakemeyo. Ngo Semiconductors futhi dielectrics abezindaba kakhulu ukubuyeka ngakho nokuningi resistivity.

izingxenye ezifana kagesi efana Semiconductors liphinyiselwe lokushisa ukwencika resistivity. Njengoba kwanda lokushisa, ngokuvamile encishisiwe.

Ngakho, Semiconductor amadivayisi - lawa zobuchwepheshe okuyinto usebenze esekelwe izinqubo ezithile e izithako okuthiwa Semiconductors. Bathola isicelo eye yasakazwa kabanzi. Ngokwesibonelo, e-electronics kanye nobunjiniyela bukagesi Semiconductor amadivayisi asetshenziswa ukuguqula ezihlukahlukene amasignali, ukuvama kwazo, ukuphakama kwawo namandla awo, kanye neminye imingcele. Ngo mathuluzi amandla asetshenziselwa energy conversion.

amadivaysi Semiconductor kungenziwa labizwa ngezindlela ezahlukene. Ngokwesibonelo, eyaziwa izindlela ngezigaba ngokuvumelana nesimiso isinyathelo, njengoba kuhlosiwe by design, ubuchwepheshe womshini Amasimu nezindawo kwesicelo, wohlobo izinto.

Nokho, ziyoba khona okuthiwa amakilasi core, okuyinto njani kudivayisi Semiconductor. La makilasi zihlanganisa:

- Electroconversion amadivayisi wedwa iguqulwe ibe namanye amagugu;

- Optoelectronic, okuyinto ukuguqula ukukhanya zibe uphawu lukagesi futhi okuphambene nalokho;

- okuqinile-isimo converters isithombe;

- amadivayisi thermoelectric ukuthi ukuguqula energy ezishisayo ku-energy kagesi;

- magneto futhi kagesi amadivayisi;

- piezoelectric kanye uhlobo.

A esihlukile Amadivayisi ezifana amadivaysi Semiconductor kungenziwa ngokuthi izifunda ehlangene, okuyinto ngokuvamile kuxutshwe, isb isethi kuhlanganiswe izici e idivayisi olulodwa.

Ngokuvamile, amadivayisi Semiconductor akhiqizwa zezindlu Ceramic noma plastic, kodwa kukhona okukhethwa kukho okungaphakejiweunpackaged.
