2.Kedu ihe bụ semiconductor?

Ka anyị malite na ihe semiconductor bụ.Site n'echiche ihe onwunwe: semiconductor bụ ihe nwere ihe ndị na-eme ka ọ dị n'etiti ndị na-eduzi na ihe mkpuchi na ụlọ okpomọkụ.Dị ka ọ dị na ndụ kwa ụbọchị, ọla kọpa na aluminom wires bụ ndị na-eduzi, ebe roba na ihe ndị yiri ya bụ ihe mkpuchi.N'ihe gbasara eletriki eletrik: semiconductor bụ ihe eji arụ ọrụ eletrik na-achịkwa, sitere na insulator ruo onye nduzi.

Njirimara anọ nke semiconductors.

Enwere ike ịchọta nchọpụta nke semiconductors ruo 1833, mgbe Faraday, onye ọkà mmụta sayensị Britain, na nna nke ngwá electronic, bụ onye mbụ chọpụtara na nguzogide nke sulfide ọlaọcha dịgasị iche na okpomọkụ dị iche na nke ọla nkịtị, nke bụ nke mbụ. nchọpụta nke semiconductor phenomen.

Mana nchịkọta nke akụrụngwa nke semiconductor emechabeghị ruo Disemba 1947 site na Bell Laboratories.

Ọnọdụ okpomọkụ na-ebili, na nkwụsị na-ada: nkwụsị nke semiconductor na-ebelata ka okpomọkụ na-ebili, ma, n'ozuzu, nkwụsị nke ígwè na-abawanye na okpomọkụ.

Mmetụta fotovoltaic: nkwụsị nke a na-emepụta site na kọntaktị n'etiti semiconductor na electrolyte na-emepụta voltaji mgbe ekpughere ìhè.

Mmetụta fotoconductive: conductivity nke semiconductor na-abawanye na ọnụnọ nke ìhè.

Mmetụta mmezi: conductivity nke semiconductor bụ ntụziaka na njikọ na ntụziaka nke ọkụ eletrik etinyere.Tinye voltaji dị mma na nsọtụ nke semiconductor na ọ na-eduzi;ọ bụrụ na a na-atụgharị polarity voltaji, ọ dịghị mma.
