Fais fab transistor thiab photo transistor

Lub hwj chim transistor tau muab txhais ua ib qho loj heev transistor los ntawm lus Askiv Giant Transistor. Nws yog Bipolar Junction Transistor (BJT) uas tiv taus qhov hluav taws xob siab thiab siab tam sim no, yog li nws qee zaum hu ua Power BJT. Nws cov yam ntxwv yog: siab tiv taus voltage. Tam sim no loj, cov yam ntxwv hloov pauv tau zoo, tab sis kev tsav tsheb yog qhov nyuaj thiab lub zog tsav tsheb loj; Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm GTR thiab qhov zoo tib yam bipolar junction transistor yog tib yam.

Phototransistor

Lub phototransistor yog ib qho khoom siv hluav taws xob photovoltaic tsim los ntawm peb lub davhlau ya nyob twg xws li bipolar transistor lossis lub teb cuam tshuam transistor. Lub teeb yog absorbed nyob rau hauv lub active cheeb tsam ntawm xws li pab kiag li lawm, tsim yees duab-tsim nqa khoom uas tsim photocurrent nce los ntawm ib tug internal hluav taws xob amplification mechanism. Lub phototransistor ua haujlwm ntawm peb qhov kawg, yog li nws yooj yim kom ua tiav kev tswj hluav taws xob lossis hluav taws xob synchronization. Cov khoom siv rau phototransistors feem ntau yog gallium arsenide (GaAs), uas feem ntau yog muab faib ua bipolar phototransistors, teb cov nyhuv phototransistors thiab lwm yam khoom siv. Bipolar phototransistors feem ntau muaj qhov nce siab tab sis tsis nrawm heev. Rau GaAs-GaAlAs, qhov kev nthuav dav tuaj yeem ua tau ntau dua 1000 thiab lub sijhawm teb yog ntau dua nanoseconds. Nws yog feem ntau siv hauv photodetectors thiab hauv optical amplification. Lub teb cov nyhuv phototransistor muaj cov lus teb ceev ceev (kwv yees li 50 picoseconds), tab sis qhov tsis zoo yog tias thaj chaw photosensitive yog me me thiab qhov nce me me (qhov kev nthuav dav tuaj yeem loj dua 10), uas feem ntau siv los ua kev kub ceev heev. photodetector. Nrog rau qhov no, muaj ntau lwm yam khoom siv optoelectronic uas yog tus cwj pwm los ntawm kev ceev ceev (lub sij hawm teb ntawm kaum tawm picoseconds) thiab tsim nyog rau kev koom ua ke. Cov khoom siv zoo li no yuav tsum pom daim ntawv thov hauv kev sib koom ua ke optoelectronic.
