Me yasa kwakwalwan kwamfuta (ko masana'anta na lantarki) ke amfani da semiconductor maimakon masu gudanarwa?
Semiconductors sun zama muhimmin ɓangare na rayuwa kuma amfani da su yana da yawa.Idan ba tare da na'urorin lantarki ba, ba za a sami rediyo ba, ba kwamfutoci, babu wayoyin hannu, babu TV, babu injin wanki, babu wasannin bidiyo, kuma babu shakka babu bugu na 3D, tuƙi mai cin gashin kansa, magani mai wayo, ko ɗaukar hoto.Haɓaka saurin bunƙasa Intanet na Abubuwa kuma ya sa na'urar daukar ma'aikata ta zama mafi dacewa.
Duk da dogaro da fasahar bututu (vacuum tubes, kuma aka sani da electron tubes, an maye gurbinsu da semiconductor saboda dalilai na tsada, rashin ƙarfi, girma, da ƙarancin inganci, tare da na'urorin lantarki da filaments a ciki waɗanda ke gudana), yawancin na'urorin lantarki sun kasance. halitta.Idan aka waiwayi zamanin injin bututu, talabijin, na'urar daukar hoto, da radiyo duk suna dauke da da'irorin bututun injin da ke bukatar dumama mintuna da yawa a duk lokacin da aka kunna su kuma ba su da kwanciyar hankali.A cikin shekaru 60 da suka gabata, fasahar semiconductor ta ƙyale na'urori su zama mafi sauri, ƙarami, da kwanciyar hankali.
Don haka me yasa amfani da semiconductors don yin waɗannan na'urorin lantarki, maimakon masu gudanarwa?
Menene semiconductors?Semiconductor wani abu ne da ke gudanar da wutar lantarki tsakanin madugu (yawanci karfe) da insulator (mafi yawa yumbu).Semiconductors na iya zama abubuwa masu tsabta (siliki ko germanium) ko mahadi (gallium arsenide ko cadmium selenide).A cikin aiwatar da doping, ana ƙara ƙananan ƙazanta zuwa na'ura mai tsabta mai tsabta, wanda ya haifar da canji mai mahimmanci a cikin ƙarfin lantarki na kayan.
Yawancin na'urorin lantarki ana kera su ne ta hanyar transistor, wanda kuma suna yin ayyuka irin su amplification, oscillators, da lissafi, wanda duk semiconductor ke yin su.
Don haka me yasa semiconductors kuma ba masu gudanarwa ba?
Saboda semiconductor yana da nau'ikan nau'ikan abubuwan gudanarwa, masu gudanarwa suna da manyan abubuwan gudanarwa kawai, waɗanda ba koyaushe ake buƙata a rayuwar yau da kullun ba.Tare da semiconductor da doping da suka dace, ana iya canza halayen aiki bisa ga buƙatu.A lokaci guda kuma, ba zai yiwu a yi amfani da dope conductors ba, yanayin da ba a iya sarrafa shi ya sa ba zai yiwu a cimma ainihin abin da ake bukata ba (yi tunanin cewa masu gudanarwa suna da adadi mai yawa na masu ɗaukar kaya kuma doping yana da ɗan tasiri).
Idan aka dauka cewa maki A da B a da’ira suna da alaka da madugu, to za a samu wutar lantarki a tsakaninsu kuma na yanzu zai gudana tsakanin maki biyu;babu wata hanyar da za a iya sarrafa magudanar ruwa a nan.Akasin haka, idan maki A da B sun haɗa ta hanyar insulator, na yanzu ba zai gudana ba kuma akwai ɗan abin da za a iya yi don ƙyale wutar lantarki ta gudana (sai dai idan an ƙara ƙarfin lantarki zuwa matakin da ba a iya kwatantawa).
Koyaya, idan ana amfani da transistor tsakanin maki A da B, yana ba da hanya mai ƙarfi don sarrafa halin yanzu.Transistor yana zaune a tsakanin maki A da B, yana ƙara sabon ma'auni C ta yadda yin amfani da bambancin ƙarfin lantarki tsakanin maki C da B zai sa na'urar ta fara gudana tsakanin A da B. Ana iya aiwatar da su a ƙananan ƙarfin lantarki (kasa da 5 volts). ) da ƙananan igiyoyin ruwa (ƙananan amfani da wutar lantarki).Ba zai yiwu a yi amfani da madugu kawai ko insulators ba.Saboda masu gudanarwa koyaushe za su yi aiki, insulators ba za su taɓa yin aiki ba kuma kawai semiconductor ne kawai ke samun buɗewa da rufewa.
Ba tare da la'akari da matsananciyar 'yan wasa ba (wasu za su ce su ɗauki ɗan tiger), yawancin mutane za su zaɓi cat.Ga matsananciyar 'yan wasa, za ku zaɓi babban damisa?Dalilin da ya sa shi ne: wanda ba a iya sarrafa shi da kuma taurin kai.Yana kama da madugu da semiconductor.
Tiger = madugu (babu iko akan gudanarwa)
Cat = semiconductor (za'a iya sarrafa aiki ta hanyar doping)
Duniyar kimiyya tana da tsauri kuma duk fasahar da ba ta da iko ba za ta dawwama ba.
