Hall haska

A Hall sakamako ne dalilin da amfani da na kowa fasahar for maras lamba rijista lokaci na kimantawa, motsi da kuma gudun juyawa daga ferromagnetic abubuwa.

Mene ne Hall haska, yana yiwuwa su fahimta, to fahimta a sakamako matakai abin da ke faruwa a cikin shi. A lokacin nassi na yanzu ta hanyar farantin jiki a cikin tsaye shugabanci a lokacin da a halin maganaɗisu filin auku a karshen rabo daga cikin farantin karfe a wani shugabanci mai gangara zuwa yanzu motsi, wani m bambanci da aka kafa. An sa ta Lorentz dokar, wanda ya tsayar da hujjar cewa saboda tasirin da halin maganaɗisu filin tokonositeli ayan don matsawa zuwa gefuna da farantin. A sakamakon m bambanci ne kai tsaye na gwargwado ga girma da vector samfurin na filin ƙarfi ne, kuma yanzu H • I.

A cikin rashi na Magnetic filin a electron juyi ba ya faruwa murdiya. Lokacin da wani Magnetic filin Lorentz sojojin da hannu a kin amincewa da electrons da sa lankwasawa na trajectories. Wadannan hanyoyi ne hanyar jari na korau zargin a gefe daya daga cikin farantin. A daura da gefen farantin hidima a matsayin site na jari na wani uncompensated tabbatacce cajin. A taro na zargin a kan surface na daura fuskoki da farantin ne dalili na lantarki filin a cikin gangara shugabanci, wanda aka kira da Hall filin. A tsari ya ci gaba har sai da cajin ajiya har bayyana gangara EMF ba rama domin sojojin da aka generated da Magnetic filin. Sa'an nan kuma Ya daidaita tsit tsari yanayin, a cikin abin da electrons matsawa a layi daya shugabanci da gefuna da farantin, kamar yadda a cikin rashi na Magnetic filin.

Hall haska, yin kayan

A semiconductor abu na wani Hall haska a kerarre, da m ya zama ba kawai high, amma kamar yadda kadan ne sosai dogara a kan dabi'u na zazzabi, da aka sani da Hall coefficient, da kuma motsi da dako ikon. Domin selection na semiconductor abu (manufa - to sa Hall haska) ya shiryar da yankin na amfani.

A Hall coefficient aka bayyana ta da bukatar ji daga Magnetic filin shigar da, da na yanzu ta hanyar da samfurin tare da kafa ta kauri. Tare da sanin darajar da Hall coefficient, yana yiwuwa ya tsayar da taro na cajin yan dako a jikin farantin, wanda shi ne inversely na gwargwado ga samfurin na Hall coefficient na electron cajin.

Semiconductors yawanci amfani da gaban lantarki madugu saboda gaskiyar cewa suna da yawa mafi girma m motsi fiye da wadanda semiconductors cewa nuna p-type watsin. Tabbata a san cewa jiki Properties na semiconductor kayan iya zama batun da muhimmanci canje-canje, dangane da abin da irin da kuma yadda mutane da yawa impurities za a gabatar a gare su.

Hall haska fasahar ga masana'antu

Don tsirar a semiconductor wafer don amfani a cikin Hall haska iya zama kamar haka:

1. Hall sha crystal farantin da ake so siffar da guda crystal mashaya.

2. Samu Hall farantin da substrate by spraying da thinnest yadudduka na semiconductor kayan.

Bigiren Hall na'urori masu auna sigina

Amfani da mikakke Hall na'urori masu auna sigina suke shiga ko'ina a cikin hanyar:

- yanzu na'urori masu auna sigina.

- actuators tare da m gudun;

- iko haihuwarka da kuma mota kariya.

- matsayi na'urori masu auna sigina.

- kwarara na'urori masu auna sigina.

- Motors brushless DC .

- contactless potentiometers.

- juyawa kwana haska.

- gane ferromagnetic jikinsu.

- vibration na'urori masu auna sigina.

- tachometer.

Bayani saita kawo a cikin labarin zai zama da taimako ga mai karatu a taron na tattaunawa a kan abin da yake a Hall haska.
