Transistor kev txhim kho keeb kwm

Thaum Lub Kaum Ob Hlis 23, 1947, hauv Bell Labs hauv Murray Hill, New Jersey, peb tus kws tshawb fawb—Dr. Bading, Dr. Brighton, thiab Dr. Shawley, sim nervously thiab methodically. Lawv tab tom sim nrog amplifying suab signals nrog semiconductor crystals nyob rau hauv conductor circuits. Peb cov kws tshawb fawb tau xav tsis thoob thaum pom tias qhov me me ntawm tam sim no dhau los ntawm cov cuab yeej uas lawv tau tsim tuaj yeem tswj tau qhov tam sim no loj dua ntws los ntawm lwm qhov, yog li ua rau muaj kev cuam tshuam loj. Cov cuab yeej no yog lub sijhawm ua tiav hauv keeb kwm ntawm kev tshawb fawb thiab thev naus laus zis - transistor. Vim tias nws tau tsim nyob rau Christmas Eve, thiab nws muaj kev cuam tshuam loj heev rau tib neeg lub neej yav tom ntej, nws hu ua "khoom plig Christmas rau lub ntiaj teb." Peb tus kws tshawb fawb yog li no yeej xyoo 1956 Nobel nqi zog hauv Physics.

[2] Kev tshawb fawb tshiab tau pom tias ib txheej ntawm cov khoom siv sib xws tuaj yeem tso tawm sab nraum lub substrate ntawm qhov kawg ntawm cov transistor electron los ua ib qho semiconductor-cooled PN qauv vim hais tias lub zog hluav taws xob theem ntawm cov khoom N yog tsawg thiab lub zog hluav taws xob. qib ntawm cov khoom siv P yog siab. Thaum ntws los, nws yog ib qho tsim nyog los kos cov cua sov los ntawm lub substrate, uas muab txoj hauv kev zoo rau lub tshav kub dissipation ntawm transistor core. Vim tias cov cua sov uas tau muab tshem tawm yog proportional rau qhov loj ntawm qhov tam sim no, kev lag luam kuj hu qhov no "hluav taws xob" tshuab cua txias. Cov cua txias triodes tshiab hu ua N-PNP lossis NPN-P, nyob ntawm qhov polarity ntawm cov khoom tshiab ntxiv.

Transistors txhawb nqa thiab coj txog "kev hloov pauv hauv lub xeev," uas tig mus rau kev lag luam semiconductor electronics thoob ntiaj teb. Raws li lub ntsiab lus tseem ceeb, nws tau siv ua ntej thiab qhov tseem ceeb hauv cov cuab yeej sib txuas lus raws sijhawm thiab thoob ntiaj teb, thiab tau tsim cov txiaj ntsig kev lag luam loj. Txij li thaum transistors tau hloov tag nrho cov qauv ntawm hluav taws xob circuits, integrated circuits thiab loj-scale integrated circuits tau tshwm sim, thiab kev tsim cov khoom siv high-precision xws li high-speed electronic computers tau dhau los ua qhov tseeb.
