Silicon hlau rau Doping
Silicon hlau feem ntau yog siv rau doping nyob rau hauv semiconductor kev lag luam, qhov twg impurities yog txhob txwm ua tswvcuab rau hauv silicon siv lead ua lattice los hloov nws cov khoom hluav taws xob. Doping ua lub luag haujlwm tseem ceeb hauv kev tsim cov cheeb tsam sib txawv thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob, xws li transistors thiab diodes.

Cov txheej txheem doping feem ntau suav nrog kev qhia qhov xav tau impurities rau hauv silicon crystal lattice los ntawm ntau txoj hauv kev. Ib txoj hauv kev zoo tshaj plaws yog ion implantation, qhov twg cov ions nquag ntawm cov yam xav tau impurity tau nrawm thiab cog rau hauv silicon substrate. Lwm txoj kev yog diffusion, qhov twg cov impurities yog tso rau ntawm silicon nto thiab ces diffused rau hauv cov qauv siv lead ua los ntawm cua sov. Cov txheej txheem doping yog ua tib zoo tswj kom ua tiav qhov xav tau concentration thiab faib cov impurities hauv silicon substrate.
Doping nrog silicon hlau tso cai rau kev tsim ntau hom semiconductors (n-type lossis p-type) los ntawm kev hloov kho tus naj npawb ntawm cov electrons dawb lossis qhov nyob hauv silicon crystal lattice. Cov cheeb tsam doped no tsim lub hauv paus rau kev txhim kho ntau yam khoom siv hluav taws xob, suav nrog cov transistors, diodes, thiab kev sib xyaw ua ke. Los ntawm kev tawm tswv yim doping silicon nrog cov impurities tshwj xeeb, hluav taws xob tus cwj pwm ntawm cov khoom tuaj yeem raug kho kom tau raws li cov kev cai ntawm cov ntawv thov hluav taws xob tshwj xeeb.
