Matransistor: Nheyo yeTekinoroji Yemazuva Ano
Pendauluan
Transistor ingangove imwe yezvakagadzirwa zvakakosha zvikuru muzana remakore rechi20, zvichichinja nyika yetekinoroji. Haisi chinhu chakakosha chete mumidziyo yakasiyana-siyana yemagetsi, asi yakakurudzirawo hunyanzvi muzvikamu zvakasiyana-siyana zvetekinoroji nesainzi. Chinyorwa chino chichakurukura zvakadzama kuti transistor chii, nhoroondo yayo, mashandiro ayo, uye pesvedzero yayo pakukura kwetekinoroji yemazuva ano.
Chii chinonzi Transistor?
Zvichitaurwa zviri nyore, transistor chikamu che semiconductor chinoshandiswa kudzora magetsi. Transistor ine mabasa maviri makuru: se switch kana amplifier. Mukushandura, transistor inogona kubatidza kana kudzima kufamba kwemagetsi. Se amplifier, transistor inogona kuwedzera chiratidzo chemagetsi chinouya.
Nhoroondo yeTransistors
Transistor isati yagadzirwa, machubhu evacuum aishandiswa zvakanyanya mumagetsi. Zvisinei, machubhu evacuum aiva nematambudziko: aive akakura, aidziya nyore nyore, uye asingashande zvakanaka. Saka, vaongorori vakatanga kutsvaga mhinduro dzinoshanda uye dzinoshanda.
Muna 1947, masayendisiti matatu kubva kuBell Laboratories—John Bardeen, Walter Brattain, naWilliam Shockley—vakagadzira transistor yekutanga. Kuwanikwa uku kwakakonzerwa nekutsvagurudza kwakakura pamusoro pehunhu hwema semiconductors. Nekuda kwekubudirira uku, vakapihwa Mubairo weNobel muFizikisi muna 1956.
Mhando dzeTransistors
1. Bipolar Transistor (Bipolar Junction Transistor/BJT):
Zvine mhando mbiri, NPN nePNP, ma transistors aya anoshanda zvichienderana nekuyerera kwemagetsi kubva pachigadziko kuenda ku emitter. MaBJT anowanzo shandiswa mukushandiswa kwekuwedzera masaini nekuda kwekugona kwawo kupa magetsi akakwira.
2. Transistor yeMunda (FET):
Kusiyana nemaBJT, maFET anodzora kuyerera kwemagetsi kuburikidza nemagetsi. Rudzi rwakajairika rweFET iMOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), iyo inoshandiswa zvakanyanya mumaseketi edhijitari nemakomputa.
Nheyo yekushanda kweTransistor
1. Bipolar Transistor (BJT):
MuBJT, mune zvikamu zvitatu zve semiconductor: emitter, base, uye collector. MuNPN transistor, kana voltage diki ikaiswa pabase, magetsi anoyerera kubva pa emitter kuenda kubase uye ozoenda ku collector. Maitiro aya anobvumira transistor 'kuvhura' kana 'kudzima' magetsi makuru emagetsi.
2. Transistor yeField Effect (FET):
FET ine materminal matatu: tsime, gedhi, uye drain. Kana voltage ikaiswa pagedhi, simba remagetsi rinobuda rinodzora kufamba kwemagetsi pakati petsime nedrain. Izvi zvinoita kuti maFET ashande zvakanaka mukushandiswa kwemagetsi mashoma.
Kushandiswa kweTransistors muTekinoroji Yemazuva Ano
1. Makomputa nemaMicroprocessor:
Matransistor ndiwo chivako chikuru mukuvaka ma microprocessor emazuva ano. Microprocessor yemazuva ano inogona kuva nemabhiriyoni ema transistors anoshanda se microswitches kuti aite mirairo ine musoro, zvichiita kuti komputa ikwanise kuita mabasa akaoma nekukurumidza uye nemazvo.
2. Kutaurirana Nefoni:
Mafoni atinoshandisa zuva nezuva anonyanya kushandisa ma transistors ari mumachipisi avo ekugadzirisa data, kuwedzera masaini, uye mamwe mabasa akasiyana-siyana. Pasina ma transistors, miniaturization uye kushanda zvakanaka kunoita kuti mafoni akwanise kushanda hazvingakwanisike.
3. Zvigadzirwa zvemagetsi zvevatengi:
Zvigadzirwa zvakaita sematerevhizheni, maredhiyo, uye michina yekurira zvinoshandisa ma transistors pakugadzirisa masaini uye kuwedzera simba remagetsi. Mumidziyo yekurira, ma transistors anoshandiswa muma amplifiers kupa ruzha rwakajeka uye rune simba.
4. Bhizinesi reMotokari:
Mota dzemazuva ano dzine magetsi akachinjika, kubva kumasystem e infotainment kusvika kumasystem ekutonga injini uye ekudzora utsi.
5. Zvishandiso zvekurapa:
Midziyo yekurapa yakaita seyekuongorora moyo nemimwe michina yekuongorora inoshandisa ma transistors kuona kuti mashandiro acho akavimbika uye akarurama.
Remangwana reVashanduri
Nekufambira mberi kwetekinoroji, ma transistors ari kuramba achivandudza hukuru uye mashandiro. Imwe nzira inokosha ndeye miniaturization kuburikidza ne nanometer technology, iyo inobvumira ma transistors akawanda kuiswa pane imwe chip pasina kuwedzera saizi ye chip pachayo.
Tsvagiridzo iri kuenderera mberiwo muzvinhu zvitsva zve semiconductor zvakaita se graphene ne molybdenum disulfide, izvo zvinogona kupa kumhanya kwakanyanya uye kushanda nesimba kuri nani zvichienzaniswa ne silicon yechinyakare.
Pamusoro pezvo, makomputa equantum inzvimbo imwe chete iyo ma transistors echinyakare anogona kutsiviwa nema qubits, mayuniti ekutanga mu quantum computing, asi ma transistors acharamba achiita basa rakakosha mukudzora nekuyera mamiriro ema qubits iwayo.
Penutup
Matransistor haasi zvinhu zvidiki chete mumasekete emagetsi; ndiwo hwaro hwetekinoroji yemazuva ano yatinofarira nhasi. Kubva kumakomputa kusvika kumidziyo yekurapa nemafoni, matransistor anoita basa rakakosha uye rakapararira. Sezvinhu zvinodzora kufamba kwemagetsi, matransistor akavhura mukana wezvinhu zvitsva zvakawanda uye akagonesa kufambira mberi kunoshamisa kwetekinoroji muminda yakasiyana-siyana.
Nekuwana zvinhu zvitsva nguva dzose, ramangwana remuchina we transistor rinotaridzika rakajeka sezvakaitika kare. Tsvagiridzo itsva nezvinhu zvitsva zvicharamba zvichipfuura miganhu yezvinogoneka, zvichiita kuti ma transistor arambe ari chikamu chakakosha chenyika yedu yetekinoroji.
