Maxay chips (ama wax soo saarka elektarooniga ah) u isticmaalaan semiconductors halkii ay ka isticmaali lahaayeen kirishbooyada?
Semiconductors waxay noqdeen qayb muhiim ah oo nolosha ka mid ah isticmaalkooduna waa mid meel walba taagan.La'aanteed semiconductors, ma jiraan raadiyoo, kombiyuutaro, telefoonada gacanta, TV-yada, mashiinada dharka, ma jiro ciyaaraha fiidiyowga, iyo hubaal ma jiraan daabacaadda 3D, baabuur wadista, daawo caqli-gal ah, ama sawir-qaadista.Horumarka degdega ah ee Internetka Waxyaabaha ayaa sidoo kale ka dhigay semiconductors xitaa wax badan oo la taaban karo.
In kasta oo lagu tiirsanaado tignoolajiyada tuubbada vacuum (tuubooyinka vacuum, sidoo kale loo yaqaan tuubooyinka elektarooniga ah, ayaa lagu beddelay semiconductors sababo qiimo sare leh, adkeysi la'aan, cabbirka, iyo waxtarka hooseeya, oo leh koronto iyo fiilooyin gudaha ku jira oo korantada ah), aalado badan oo elektiroonig ah ayaa ahaa abuuray.Dib u milicsiga waayihii tuubada faakuumka, telefishinada, cod-garaafka, iyo idaacadaha dhamaantood waxa ay ka koobnaayeen wareegyada tuubada faakuumka oo u baahan dhawr daqiiqadood oo diirimaad ah mar kasta oo la shido aad bayna u degganayn.60-kii sano ee la soo dhaafay, tignoolajiyada semiconductor waxay u ogolaatay aaladaha inay noqdaan kuwo dhakhso badan, yar yar, oo deggan.
Haddaba maxay tahay sababta loo isticmaalo semiconductors si loo sameeyo aaladahan elektiroonigga ah, halkii aad ka ahaan lahayd kirishbooyada?
Waa maxay semiconductors?Semiconductor-ku waa shay koronto ka dhex shaqeeya daareeyaha (badanaa birta) iyo dahaarka (inta badan dhoobada).Semiconductors waxay noqon karaan walxo saafi ah (silikon ama germanium) ama xeryahooda (gallium arsenide ama cadmium selenide).Habka doping-ka, qadar yar oo wasakh ah ayaa lagu daraa semiconductor saafi ah, taasoo keentay isbeddel weyn oo ku yimaada korantada qalabka.
Inta badan aaladaha elegtarooniga ah waxa lagu farsameeyaa transistor-ka, kuwaas oo iyaguna qabta hawlo ay ka mid yihiin cod-weyneysiinta, oscillators, iyo xisaabaadka, kuwaas oo dhamaantood ay sameeyaan semiconductors.
Haddaba waa maxay sababta semiconductors oo aan ahayn kirishbooyada?
Sababtoo ah semiconductors waxay leeyihiin habab badan oo kala duwan, kirishbooyadu waxay leeyihiin kaliya conductivities aad u sarreeya, kuwaas oo aan had iyo jeer looga baahnayn nolol maalmeedka.Iyada oo la adeegsanayo semiconductors iyo doping habboon, conductivity waa la bedeli karaa iyadoo loo eegayo shuruudaha.Isla mar ahaantaana, suurtagal ma aha in la xakameeyo dope-ka, dabeecadda aan la xakameynin taas oo ka dhigaysa mid aan suurtagal ahayn in la gaaro sida saxda ah ee loo baahan yahay ( qiyaasi in kirishbooyayaashu ay leeyihiin tiro badan oo xajmi ah iyo doping-ku saameyn yar).
Haddii aan ka soo qaadno in dhibcaha A iyo B ee wareegga ay ku xiran yihiin kombuyuutar, waxaa jiri doona danab u dhexeeya iyaga oo hadda socda ayaa u dhexeeya labada dhibcood;ma jirto si loo xakameeyo socodka hadda halkan.Taa beddelkeeda, haddii dhibcaha A iyo B ay ku xidhmaan insulator, hadda socdaa ma qulquli doono oo wax yar ayaa la samayn karaa si loogu oggolaado socodka hadda (haddii aan korantada la kordhin heer aan la qiyaasi karin).
Si kastaba ha noqotee, haddii transistor loo isticmaalo inta u dhaxaysa dhibcaha A iyo B, waxay bixisaa hab awood leh oo lagu xakameynayo hadda.Transistor-ku wuxuu u dhexeeyaa dhibcaha A iyo B, isagoo ku daraya dhibic cusub oo C si marka la isticmaalo farqiga danab ee u dhexeeya dhibcaha C iyo B waxay keenaysaa in hadda uu bilaabo qulqulka u dhexeeya A iyo B. Kuwaas waxaa lagu fulin karaa koronto aad u hooseeya (ka hooseeya 5 volts). ) iyo mawjadaha hooseeya (isticmaalka tamarta hoose).Suurtagal maaha in la isticmaalo kirishbooyada ama insulators kaliya.Sababtoo ah kirishbooyada ayaa had iyo jeer qaban doona, insulators weligood ma dhaqmi doonaan oo kaliya semiconductors ayaa gaari doona furitaanka iyo xidhitaanka.
Iyaga oo aan tixgalin ciyaartoyga xad dhaafka ah (qaar ayaa odhan lahaa door shabeelka), dadka badankiisu waxay dooran lahaayeen bisad.Ciyaartoyda aadka u daran, ma dooran lahayd shabeel weyn?Sababta cad waa: aan la xakameyn karin iyo cabsida.Waxay aad ugu eg tahay kirishbooyada iyo semiconductor.
Shabeel = kaari (ma laha koontaroolka dhaqdhaqaaqa)
Bisad = semiconductor (dhaqanka waxaa lagu xakameyn karaa doping)
Dunida cilmigu waa mid adag oo tignoolajiyad kasta oo aan la xakamayn karin ma sii jiri doonto.
