Mmetụta piezoelectric

Mgbe ụfọdụ dielectrics na-emeziwanye site n'itinye ike na ntụziaka ụfọdụ, a na-emepụta ụgwọ n'elu elu, ma mgbe a na-ewepụ ike dị n'èzí, ha na-alaghachi na steeti a na-akwụghị ụgwọ.A na-akpọ ihe omume a nke ọma mmetụta piezoelectric.Mgbe a na-etinye ọkụ eletrik na ntụziaka polarization nke dielectric, dielectric ga-emepụta nrụrụ igwe ma ọ bụ nrụgide ígwè ọrụ n'akụkụ ụfọdụ.Mgbe e wepụrụ oghere eletrik dị n'èzí, nrụrụ ma ọ bụ nrụgide ga-apụ n'anya, nke a na-akpọ mmetụta piezoelectric inverse.

Piezoelectric mmewere

Ihe mmetụta Piezoelectric bụ ihe mmetụta anụ ahụ yana ihe mmetụta ike ike.Ihe eji eme piezoelectric a na-ejikarị bụ Shi Ying crystal (SiO2 _2) na seramiiki piezoelectric sịntetik.

Piezoelectric mgbe niile nke ceramics piezoelectric bụ ugboro ugboro nke Shi Ying kristal, na uche ya dị elu.

1. mmetụta fotoelectric

Mgbe ìhè na-amụba ihe, enwere ike iwere ya dị ka eriri foton nwere ike e bombarding ihe.Ọ bụrụ na ike nke photons buru ibu, electrons dị n'ime ihe ahụ ga-ewepụ ihe mgbochi nke ike dị n'ime ma nwee mmetụta eletrik kwekọrọ, nke a na-akpọ mmetụta fotoelectric.

1) N'okpuru ọrụ nke ìhè, ihe na-eme na electrons na-agbapụ n'elu ihe a na-akpọ mmetụta fotoelectric mpụga, dị ka tube foto na fotomultiplier tube.

2) N'okpuru omume nke ìhè, a na-akpọ ihe na-agbanwe agbanwe nke ihe a na-akpọ mmetụta photoelectric dị n'ime, dị ka photoresistor, photodiode, phototransistor na phototransistor.

3) N'okpuru ọrụ nke ìhè, ihe na-emepụta ike electromotive na ụfọdụ ntụziaka, nke a na-akpọ fotovoltaic phenomenon, dị ka fotovoltaic cell (ngwaọrụ na-emetụ n'ahụ ọnọdụ nke ihe merenụ ìhè ntụpọ n'elu photosensitive elu).

2 resistor mmetụta foto

Mgbe ọkụ na-agbapụta fotoresistor, electrons na-akwaga iji mepụta ụzọ abụọ-oghere eletrọn, nke na-eme ka mgbochi ahụ dị ntakịrị.Ka ọkụ na-esiwanye ike, na-ebelata nguzogide.Ìhè ahụ merenụ na-apụ n'anya, ụzọ abụọ-oghere eletrọn na-agbake, na uru nguzogide na-eji nwayọọ nwayọọ laghachi na uru mbụ ya.

3. Photosensitive tube

Ọkpụkpọ foto (photodiode, phototransistor, phototransistor, wdg) bụ nke ngwaọrụ semiconductor.

4. Electroluminescence

Ihe ngosi luminescence na-emepụta site na ihe ndị siri ike na-egbuke egbuke n'okpuru mkpali nke ọkụ eletrik ka a na-akpọ electroluminescence.Electroluminescence bụ usoro ịtụgharị ọkụ eletrik ozugbo ka ọ bụrụ ike ọkụ.Igwe ọkụ na-emitting diode (LED) bụ ngwaọrụ semiconductor electroluminescent nke ejiri ihe pụrụ iche dochie ya.Mgbe njikọ PN na-aga n'ihu na-adịghị mma, a na-emepụta ike dị ukwuu n'ihi nchikota oghere eletrọn, nke a na-ewepụta n'ụdị photon ma na-ebunye ọkụ.
