Kev piav qhia
Raws li quantum mechanics, tus cwj pwm ntawm cov hluav taws xob hauv cov khoom siv lead ua tuaj yeem piav qhia los ntawm kev xav band. Hauv cov hlau silicon, muaj qhov sib txawv ntawm lub zog loj heev, uas txhais tau hais tias cov hluav taws xob tsis tuaj yeem dhia los ntawm valence band mus rau qhov conduction band.
Qhov kev sib txawv no ua rau cov hlau silicon tsis zoo hauv cov khoom siv hluav taws xob, tab sis kuj siab heev hauv thermal conductivity. Vim hais tias nyob rau hauv tshav kub conduction, lub zog yog kis los ntawm kev co ntawm atoms, tsis electrons.
Cov qauv no muab silicon crystals siab thermal conductivity vim covalent bonds tuaj yeem hloov hluav taws xob kub.
Tsis tas li ntawd, silicon muaj cov qib siab ntawm symmetry hauv nws cov qauv siv lead ua, uas kuj pab txhim kho nws cov thermal conductivity.

Nyob rau hauv ib tug crystal, atoms yeej ib txwm vibrating. Cov kev vibrations no tuaj yeem xav tias yog suab nthwv dej. Nyob rau hauv cov ntaub ntawv ntawm silicon hlau, qhov kev co yog ceev heev vim hais tias cov bonds ntawm silicon atoms yog nruj heev.
Qhov kev vibration nrawm no tso cai rau lub zog hluav taws xob xa mus sai heev los ntawm cov siv lead ua, yog li ua kom cov thermal conductivity ntawm silicon hlau.
Doping khoom yog hais txog qhov sib ntxiv ntawm me me ntawm impurity ntsiab rau cov khoom. Hauv silicon hlau, doping tuaj yeem txhim kho nws cov thermal conductivity.
Qhov no yog vim hais tias cov ntsiab lus doping tuaj yeem hloov cov khoom ntawm lattice vibrations, ua rau nws yooj yim dua rau kev hloov hluav taws xob.
Nyob rau hauv luv luv, muaj plaub lub ntsiab yog vim li cas rau lub siab thermal conductivity ntawm silicon hlau: nws siv lead ua qauv muaj ib tug high degree ntawm symmetry thiab covalent daim ntawv cog lus; Nws cov qauv hluav taws xob muaj qhov sib txawv ntawm lub zog loj; Nws cov lattice vibrations ceev heev; Nws tuaj yeem doped los txhim kho cov thermal conductivity. Cov yam ntxwv no ua rau cov hlau silicon dhau los ua cov khoom tseem ceeb, dav siv hauv hluav taws xob, photoelectric, semiconductor thiab lwm yam.
