N-hom semiconductor tsim cov cai hais
Ob qho tib si doping thiab qhov tsis xws luag tuaj yeem ua rau nce qhov hluav taws xob ntau hauv cov khoom sib txuas. Rau cov germanium thiab silicon-based semiconductor cov ntaub ntawv, doping pawg V ntsiab lus (phosphorus, arsenic, antimony, thiab lwm yam), thaum impurity atoms hloov germanium hauv ntxaij los hloov chaw 1, silicon atoms tuaj yeem muab hluav taws xob ntxiv rau hauv kev txaus siab covalent daim ntawv cog lus ua kom sib haum. , uas ua rau kev nce qib hauv kev sib xyaw ua ke band electron concentration hauv lub tshuab hluav taws xob (semiconductor), xws li qhov tsis haum atoms yog hu ua cov neeg pub. Donors-Ⅴ cov khoom ua lag luam semiconductor feem ntau tau txais yuav pab pawg IV lossis pawg VI cov ntsiab lus. Qee qhov oxide semiconductors, xws li ZnO, Ta2O5, thiab lwm yam, cov tshuaj lom neeg sib xyaw feem ntau yog hypoxic, cov pa tawm ntawm cov pa tawm tuaj yeem qhia lub luag haujlwm ntawm cov neeg pub, yog li hom oxide no feem ntau yog hluav taws xob conductivity, uas yog Nws yog N-hom semiconductor. Cov cua kub hauv lub tshuab nqus tsev tuaj yeem txuas ntxiv txhim kho qib ntawm cov pa oxygen, uas pom tau tias cov khoom hluav taws xob muaj zog.
