Li-transistors ke likarolo tsa bohlokoa tsa elektroniki tse sebelisoang hoo e ka bang sesebelisoa se seng le se seng sa elektroniki sa sejoale-joale. Ho tloha lik'homphieutheng ho ea ho li-smartphone ho ea ho lisebelisoa tsa lapeng, li-transistors li bapala karolo ea bohlokoa lipotolohong tsa elektroniki. Sengoloa sena se ikemiselitse ho fana ka kutloisiso e tebileng ea li-transistors, kamoo li sebetsang kateng, le ts'ebeliso e fapaneng ea likarolo tsena bophelong ba letsatsi le letsatsi.
1. Selelekela ho Transistors
Transistor ke sesebelisoa sa semiconductor se eketsang kapa se timang matshwao a elektroniki. Ho na le mefuta e mmedi e meholo ya ditransistor: ditransistor tsa bipolar junction (BJTs) le ditransistor tsa field-effect (FETs). Le hoja boenjiniere ba motheo ba mefuta ena e mmedi ya ditransistor bo fapane, ka bobedi di sebetsa e le diswitjhi le di-amplifier tsa matshwao.
1.1 Sebopeho sa Motheo sa Transistor
Transistor ea BJT e na le mekhahlelo e meraro ea thepa ea semiconductor e bitsoang collector, base, le emitter. Ho FET, li-terminal tse kholo ke mohloli, heke, le drain. Ho na le mefuta e 'meli ea li-transistor tsa BJT:
– NPN (emitter-negative, base-positive, collector-negative)
– PNP (emitter-positive, base-negative, collector-positive)
Li-FET le tsona li na le mefuta e 'meli e meholo:

Diphuputso mabapi le thepa e ncha, tse kang di-semiconductor tsa III-V tse nang le motsamao o phahameng wa carrier ho feta silicon, di fana ka bokgoni ba ho hlola tse ding tsa diphephetso tse tobaneng le di-transistors tsa silicon tse tlwaelehileng. Thepa ena e dumella di-transistors ho sebetsa ka potlako le ka bokgabane bo eketsehileng.
Qetello
Li-transistors ke karolo ea bohlokoa lisebelisoa tsa elektroniki tsa sejoale-joale, tse nolofalletsang boqapi le mahlale a mangata ao re a thabelang kajeno. Ho tloha ho holiseng matšoao ho ea ho sebetsa e le li-switch lipotolohong tsa dijithale, li-transistors li teng hoo e ka bang sesebelisoa se seng le se seng sa elektroniki. Tšebeliso e ntseng e eketseha le tsoelo-pele ea theknoloji li ntse li tsoela pele ho sutumelletsa meeli ea ts'ebetso, boholo le ts'ebeliso e ntle ea matla, li tšepisa bokamoso bo khanyang le boqapi.
Ka ho utloisisa metheo ea li-transistors le lits'ebetso tsa tsona, re ka ananela karolo ea tsona ea bohlokoa haholoanyane lisebelisoa tsa elektroniki 'me ra lula re tseba tsoelo-pele ea theknoloji e tlang. Joaloka bafuputsi, baenjiniere, kapa basebelisi ba theknoloji feela, kutloisiso ena e bula menyetla ea boqapi le lipatlisiso tse ling tsa elektroniki le tsa khomphutha.
