Txheej txheem txheej txheem ntawm lub qhov zoo-semiconductor
Doping trivalent cov ntsiab lus (xws li boron) hauv cov ntshiab silicon muaju los hloov txoj haujlwm ntawm silicon atoms hauv cov siv lead ua lattice ua P-hom semiconductor. Hauv P-type semiconductors, qhov muaj ntau tus menyuam thiab cov khoom siv hluav taws xob dawb yog cov menyuam yaus tsawg, uas feem ntau ua hluav taws xob los ntawm qhov. Txij li tus nqi ntawm tus nqi zoo thiab tus nqi tsis zoo nyob rau hauv P-hom semiconductor sib npaug, P-hom semiconductor yog hluav taws xob nruab nrab. Qhov tshij feem ntau yog muab los ntawm impurity atoms, thiab cov hluav taws xob dawb yog tsim los ntawm thermal excitation.
