Zvakakoshawo kuti chigadzirwa ichi chinoshandiswa kunze, sezvo chichakundikana kana chikaiswa munzvimbo ine hunyoro.

Kana ikozvino yakakwana inoshandiswa kune zener diode, kudonha kwemagetsi kunogadzirwa. Kana iyi voltage ikasvika kana kudarika kuparara kwemagetsi emuchina, saka inobvumira ikozvino kuyerera kubva kune imwe terminal.

chiedza emitting diode (LED)

A light emitting diode (LED) inogadzirwa ne semiconductor zvinhu zvinoburitsa chiedza kana huwandu hwakakwana hwemagetsi huchipfuura nemo. Chimwe chezvinhu zvakakosha zvema LEDs ndezvekuti vanoshandura simba remagetsi kuita optical energy zvakanyanya. Ma LED anoshandiswawo semwenje mwenje kuratidza zvinonangwa pamidziyo yemagetsi senge makomputa, wachi, maredhiyo, terevhizheni, zvichingodaro.

Iyo LED muenzaniso wekutanga wekuvandudzwa kweiyo microchip tekinoroji uye yakagonesa shanduko huru mumunda wekuvhenekesa. Ma LED anoshandisa kanenge maviri semiconductor akaturikidzana kuti abudise chiedza, imwe pn junction kuti ibudise zvinotakura (electrons nemaburi), zvinozotumirwa kumativi akapesana e "barrier" layer inobata maburi kune rimwe divi uye maerekitironi kune rimwe. . Simba revatakuri vakabatwa rinosanganiswa zvakare mu "resonance" inozivikanwa se electroluminescence.

LED inoonekwa semhando inoshanda yekuvhenekesa nekuti inoburitsa zvishoma kupisa pamwe nechiedza chayo. Iine hupenyu hurefu kudarika mwenje we incandescent, iyo inogona kugara kusvika ka60 nguva yakareba, ine chiedza chepamusoro uye inobudisa huturu hushoma kudarika marambi efluorescent.

Kubatsira kukuru kwema LED inyaya yekuti vanoda simba shoma rekushanda, zvichienderana nerudzi rwe LED. Izvozvi zvinogoneka kushandisa maLED ane magetsi emagetsi kubva kumasero ezuva kusvika kumabhatiri uye kunyange alternating current (AC).

Kune akawanda akasiyana marudzi e LED uye anouya neakasiyana mavara anosanganisira tsvuku, orenji, yero, yegirini, yebhuruu, chena, nezvimwe. Nhasi, ma LED anowanikwa nekupenya kwe10 kusvika ku100 lumens pa watt (lm/W), iyo inenge yakafanana neyakajairwa magetsi.

Nekudaro, izvi zvinobatsira kudzikisa kumberi kwemagetsi, izvo zvinozoderedza kurasikirwa kwemagetsi uye kuwedzera kukurumidza kwekuchinja kwemidziyo inoshandisa Schottky diodes nemargin yakakura kwazvo.

Shockley Diode

Iyo Shockley diode chishandiso chesemiconductor chine asymmetric kuronga kwemagetsi. Iyo diode inoitisa ikozvino mune imwe nzira uye zvishoma kana iyo polarity ikadzoserwa. Kana magetsi ekunze akachengetedzwa paShockley diode, inozoenda mberi zvishoma nezvishoma sezvo simba rinoshandiswa richiwedzera, kusvika painodanwa kuti "cut-off voltage" apo panenge pasisina anoyemurika sezvo maerekitironi ese anobatana nemaburi. . Kupfuura iyo cutoff voltage pane iyo graphical inomiririra yezvino-voltage maitiro, kune dunhu rekupokana kwakashata. Iyo Shockley ichaita seamplifier ine negative kuramba hunhu mune ino renji.

Basa raShockley rinogona kunzwisiswa zvakanyanya nekurityora muzvikamu zvitatu zvinozivikanwa sematunhu, ikozvino mune reverse direction kubva pasi kusvika kumusoro 0, 1 uye 2 zvakateerana.

Munharaunda 1, kana magetsi akanaka akaiswa kune kurerekera mberi, maerekitironi anopararira mun-mhando semiconductor kubva kune p-mhando zvinhu, apo "depletion zone" inoumbwa nekuda kwekutsiviwa kwevatakuri vazhinji. Depletion zone ndiyo dunhu rinobviswa vatakuri vechaji kana voltage yaiswa. Iyo depletion zone yakatenderedza pn junction inodzivirira ikozvino kuyerera nepamberi peiyo unidirectional mudziyo.

Kana maerekitironi apinda mun-side kubva kudivi rep-type, "depletion zone" inoumbwa mukuchinja kubva pasi kuenda kumusoro kusvika buri nzira iripo yavharika. Makomba ari kufamba kubva kumusoro kuenda pasi anobatana zvakare nemaerekitironi achifamba kubva pasi kuenda kumusoro. Ndiko kuti, pakati penzvimbo dzekupera kwebhendi yekufambisa uye bhendi yevalence, "nzvimbo yekudzokorora" inooneka, iyo inodzivirira kuenderera mberi kwevatakuri vakuru kuburikidza neShockley diode.

Kuyerera kwazvino kwave kudzorwa nemutakuri mumwe chete, inova mutakuri wevashoma, kureva maerekitironi mune iyi n-mhando semiconductor uye maburi ep-mhando zvinhu.
