Ib daim teb -effect transistor (FET) yog ib qho khoom siv hluav taws xob unipolar uas nws tam sim no tswj los ntawm hluav taws xob teb. Nws rub tau zoo tsis muaj tam sim no lossis tsis tshua muaj tam sim no ntawm nws cov tswv yim, thiab nta cov tswv yim impedance siab, tsis tshua muaj suab nrov, zoo thermal stability, thiab kev tsim khoom yooj yim. Nws yog dav siv nyob rau hauv loj -scale thiab heev-loj-scale integrated circuits.
FETs, nrog rau lawv qhov zoo ntawm kev siv hluav taws xob tsawg, kev ua haujlwm ruaj khov, thiab muaj zog hluav taws xob tiv thaiv, yog maj mam hloov cov transistors hauv kev sib xyaw ua ke. Txawm li cas los xij, lawv tseem yog qhov muag heev. Txawm hais tias feem ntau tau tsim - hauv kev tiv thaiv diodes, lawv tseem tuaj yeem raug puas tsuaj yog tias tsis ua tib zoo saib xyuas. Yog li ntawd, ceev faj yog qhia hauv lawv daim ntawv thov.
