Magetsi ari semiconductors

Magetsi ari semiconductors - chinotungamirwa kufamba mumakomba uye maerekitironi, izvo vanotungamirirwa yemagetsi munda.

Somugumisiro kuedza, yakanga akacherechedza kuti Magetsi mu semiconductors haisi pamwe kuchinjwa nyaya - havasi zvinosanganisirei chero makemikari kuchinja. Saka, mutakuri, maerekitironi anogona kunzi mune semiconductors.

The mano acho kuti aumbe mairi magetsi anogona pakutsvaga zvariri conductivity. By chakarurama ichi conductors kugara ane zvenguva nzvimbo pakati conductors uye insulators. Semiconductors - Ndiwo marudzi akasiyana zvicherwa, dzimwe simbi, simbi sulfides, etc. Magetsi ari semiconductors zvauya kubva wevasungwa chokuzvisarudzira maerekitironi anogona kufamba directionally mune fuma. Achienzanisa nesimbi uye conductors, izvozvo zvinogona kucherechedzwa kuti pane musiyano pakati tembiricha simba pamusoro conductivity yavo. Kuwedzera tembiricha kunotungamirira kune vasanyanye ari conductivity chainge chakagadzirwa nesimbi. In semiconductors ari conduction unodiwa inowedzerawo. Kana semiconductor tembiricha vowanda, inofamba chokuzvisarudzira maerekitironi zvichava zvikuru sechisina musoro. Izvi imhaka nokuwedzera kwenhamba kwemotokari. Zvisinei, mune semiconductors tichienzanisa nesimbi, zviri kunyanya kuwedzera kuratidza arambe achirema chokusarudza maerekitironi. Zvinhu izvi zvine vanetsane pamusoro conductivity: vazhinji kwemotokari, ikava duku conductivity, mukuru wevasungwa, dzakanga ndizvo. In nesimbi, hapana kutsamira pakati tembiricha uye wevasungwa chokuzvisarudzira maerekitironi, saka kuti kuchinja conductivity pamwe kuwedzera kupisa chete zvinoderedza mukana ane akarayira inofamba chokusarudza maerekitironi. Kana semiconductor, kuratidza mugumisiro kuwedzera wevasungwa yepamusorosoro. Saka, tembiricha vosimba achava mukuru, kunokonzera conductivity.

Pane ukama pakati sangano muripo vatakuri uye izwi zvakadai Magetsi mu semiconductors. In semiconductors, undoraira vatakuri dzinoratidzwa chitarisiko siyana zvinhu, pakati zviri yakaoma tembiricha uye rucheno acho. Chakachena semiconductors akakamurwa extrinsic uye pachake.

Kana vayo kondakita, mugumisiro nouipi pane imwe tembiricha angasava zvinokosha kwavari. Sezvo boka pakaputsika semiconductors riri pasi, nenzira mukati semiconductor, apo tembiricha inosvika mhedziso razero, pane zvinodiwa yakazara Valencia maerekitironi. Asi conduction bhendi akasununguka chose; hakuna magetsi conductivity, uye chinoshanda sechinhu yakanaka insulator. Pane dzimwe tembiricha pane Zvinogoneka kuti chafariz nokufamba maduramazwi maerekitironi vanogona kukunda zvinogona mechidziro kuoneka mune conduction bhendi.

Thomson kushanda

Nheyo thermoelectric Thomson kushanda apo magetsi ari semiconductors, pamwe iyo pane tembiricha gradient mavari, asi gst boces kupisa kusunungurwa kana Absorção de Água kwohumwe yakawanda kupisa richaitika zvichienderana mirayiridzo iyo iyezvino dzichayerera.

Kushomeka yunifomu chiratidzazvizhinji kudziyisa, kuva homogeneous Murongerwo kunokanganisa ehupfumi ayo, mauri acho anova asiri yunifomu. Nokudaro, Thomson nezvinozoitika imwe kutanga Peltier. Musiyano chete ndechokuti siyana vasiri makemikari anoumba mharidzo, uye tembiricha yomunhu oga ndiye heterogeneity ichi.
