Li-transistors: Motheo oa Theknoloji ea Kajeno
Pendahuluan
Transistor e ka ’na ea nkoa e le e ’ngoe ea lintho tsa bohlokoa ka ho fetisisa tse qapiloeng lekholong la bo20 la lilemo, e fetolang lefatše la theknoloji. Hase feela hore ke karolo ea bohlokoa lisebelisoa tse fapaneng tsa elektroniki, empa e boetse e khannile boqapi mafapheng a fapaneng a theknoloji le saense. Sehlooho sena se tla tšohla ka botebo hore na transistor ke eng, nalane ea eona, hore na e sebetsa joang, le tšusumetso ea eona nts'etsopele ea theknoloji ea sejoale-joale.
Transistor ke eng?
Ka bokhutšoanyane, transistor ke karolo ea semiconductor e sebelisetsoang ho laola motlakase. Transistor e na le mesebetsi e 'meli e meholo: e le switch kapa amplifier. Lits'ebetsong tsa ho fetola, transistor e ka bulela kapa ea tima phallo ea motlakase. E le amplifier, transistor e ka holisa lets'oao la motlakase le kenang.
Histori ea Li-Transistors
Pele ho qaptjoa transistor, li-vacuum tube li ne li sebelisoa haholo lisebelisoa tsa elektroniki. Leha ho le joalo, li-vacuum tube li ne li e-na le mathata: li ne li le khōlō, li futhumatsoa habonolo, 'me li sa sebetse hantle. Ka hona, bafuputsi ba ile ba qala ho batla litharollo tse sebetsang hantle le tse sebetsang haholoanyane.
Ka 1947, bo-rasaense ba bararo ba tsoang Bell Laboratories—John Bardeen, Walter Brattain, le William Shockley—ba ile ba qapa transistor ea pele. Ho sibolloa hona e bile litholoana tsa lipatlisiso tse pharaletseng mabapi le thepa ea li-semiconductor. Bakeng sa katleho ena, ba ile ba fuoa Khau ea Nobel ho Fisiks ka 1956.
Mefuta ea Li-Transistors
1. Transistor ea Bipolar (Transistor ea Bipolar Junction/BJT):
Li entsoe ka mefuta e 'meli, NPN le PNP, li-transistors tsena li sebetsa ho latela phallo ea motlakase ho tloha botlaaseng ho ea ho emitter. Hangata li-BJT li sebelisoa lits'ebetsong tsa ho holisa matšoao ka lebaka la bokhoni ba tsona ba ho fana ka maqhubu a phahameng.
2. Transistor ea Tšusumetso ea Tšimo (FET):
Ho fapana le li-BJT, li-FET li laola phallo ea motlakase tšimong ea motlakase. Mofuta o tloaelehileng haholo oa FET ke MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), e sebelisoang haholo lipotolohong tsa dijithale le lik'homphieutheng.
Molao-motheo oa ho Sebetsa oa Transistor
1. Transistor ea Bipolar (BJT):
Ho BJT, ho na le mekhahlelo e meraro ea semiconductor: emitter, base, le collector. Ho transistor ea NPN, ha motlakase o monyane o kenngoa setsing, motlakase o phalla ho tloha ho emitter ho ea setsing ebe o ea ho collector. Ts'ebetso ena e lumella transistor ho 'bulela' kapa ho 'tima' motlakase o moholo.
2. Transistor ea Tšusumetso ea Tšimo (FET):
FET e na le li-terminal tse tharo: mohloli, heke, le drain. Ha motlakase o kenngoa hekeng, tšimo ea motlakase e hlahang e laola phallo ea motlakase pakeng tsa mohloli le drain. Sena se etsa hore li-FET li sebetse hantle haholoanyane lits'ebetsong tse nang le matla a tlase.
Tšebeliso ea Li-Transistors Theknolojing ea Sejoale-joale
1. Lik'homphieutha le Li-Microprocessor:
Li-transistors ke motheo oa bohlokoa kahong ea li-microprocessor tsa sejoale-joale. Microprocessor ea sejoale-joale e ka ba le li-transistors tse libilione tse sebetsang joaloka li-microswitch ho phethahatsa litaelo tse utloahalang, tse nolofalletsang khomphutha ho etsa mesebetsi e rarahaneng kapele le ka katleho.
2. Puisano ea Selefouno:
Li-smartphone tseo re li sebelisang letsatsi le letsatsi le tsona li itšetlehile haholo ka li-transistor tse ka har'a li-chip tsa tsona bakeng sa ts'ebetso ea data, ho holisa matšoao, le mesebetsi e meng e fapaneng. Ntle le li-transistor, miniaturization le bokgoni bo etsang hore li-smartphone li khonehe bo ne bo ke ke ba khoneha.
3. Lisebelisoa tsa Elektroniki tsa Bareki:
Lihlahisoa tse kang lithelevishene, li-radio le lisebelisoa tsa molumo li sebelisa li-transistor bakeng sa ts'ebetso ea matšoao le ho atolosoa. Lisebelisoang tsa molumo, li-transistor li sebelisoa ho li-amplifier ho fana ka molumo o hlakileng le o matla.
4. Indasteri ea Likoloi:
Likoloi tsa sejoale-joale li tletse lisebelisoa tsa elektroniki tse feto-fetotsoeng, ho tloha litsamaisong tsa boithabiso ho isa ho tsamaiso ea enjene le litsamaisong tsa taolo ea mosi o kotsi.
5. Lisebelisoa tsa Bongaka:
Lisebelisoa tsa bongaka tse kang li-monitor tsa pelo le lisebelisoa tse ling tsa tlhahlobo li sebelisa li-transistors ho netefatsa ts'ebetso e tšepahalang le e nepahetseng.
Bokamoso ba Li-Transistors
Ka tsoelo-pele ea theknoloji, li-transistor li ntse li tsoela pele ho ntlafatsa boholo le ts'ebetso. Mokhoa o mong oa bohlokoa ke miniaturization ka theknoloji ea nanometer, e lumellang li-transistor tse ngata ho beoa holim'a chip e le 'ngoe ntle le ho eketsa boholo ba chip ka boeona.
Phuputso e ntse e tsoela pele ka thepa e ncha ea semiconductor joalo ka graphene le molybdenum disulfide, tse ka fanang ka lebelo le phahameng le ts'ebeliso e ntle ea matla ha li bapisoa le silicon ea setso.
Ho phaella moo, dikhomphutha tsa quantum ke sebaka se le seng moo di-transistor tse tlwaelehileng di ka nkelwang sebaka ke di-qubit, e leng diyuniti tsa motheo tsa khomphutha ya quantum, empa di-transistor di ntse di tla bapala karolo ya bohlokwa ho laoleng le ho lekanyeng boemo ba di-qubit tseo.
Ho koala
Li-transistors ha se likarolo tse nyane feela lipotolohong tsa elektroniki; ke motheo oa theknoloji ea sejoale-joale eo re e thabelang kajeno. Ho tloha lik'homphieutheng ho ea ho lisebelisoa tsa bongaka le li-smartphone, li-transistors li bapala karolo ea bohlokoa le e atileng. Jwalo ka likarolo tse laolang phallo ea motlakase, li-transistors li butse monyako oa boqapi bo se nang palo 'me li nolofalitse tsoelo-pele e makatsang ea theknoloji masimong a fapaneng.
Ka ho sibolloa le boqapi bo sa khaotseng, bokamoso ba transistor bo shebahala bo khanya joalo ka nako e fetileng. Lipatlisiso tse ncha le thepa e ncha li tla tsoela pele ho sutumelletsa meeli ea se ka khonehang, ho netefatsa hore li-transistor li lula e le karolo ea bohlokoa ea lefats'e la rona la theknoloji.
