Semiconducting Material Metallic Silicon Powder
Silicon hlau hmoov, ua ib feem tseem ceeb ntawm cov khoom siv semiconductor, muaj nws cov yam ntxwv tshwj xeeb thiab qhov zoo. Cov khoom siv semiconductor yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub.

Kev piav qhia
Silicon yog ib qho khoom siv semi-hlau nrog cov qauv siv lead ua zoo ib yam li pob zeb diamond, uas belongs rau cov khoom siv sib xyaw ua ke zoo sib xws.
Plaub valence electrons nyob rau hauv silicon atoms koom ua ke los ntawm covalent bonds los ua ib tug crystalline qauv, tsim ib tug octahedral cell zoo li lub pob zeb diamond. Cov qauv ntawm tes no muaj kev ruaj ntseg thiab zoo ib yam, yog li silicon muaj cov khoom zoo heev semiconductor.
Lub band gap ntawm silicon hais txog qhov sib txawv ntawm qhov band conduction thiab valence band. Nyob rau hauv chav tsev kub, silicon muaj qhov sib txawv ntawm 1.1 electron volts, uas ua rau nws zoo semiconducting zog, ob qho tib si conducting thiab insulating.

Lub conductivity ntawm silicon nyob ntawm nws qhov sib txawv band. Nyob rau hauv chav tsev kub, qhov sib txawv band ntawm silicon yog loj, yog li cov electrons ntawm silicon yog nyob rau hauv lub valence band, uas tsis yog ib qho yooj yim mus tau zoo siab mus rau hauv lub conduction band, ua rau tsis muaj zog conductivity ntawm silicon.
Txawm li cas los xij, thaum lub silicon raug rau ib qho nyiaj ntawm lub zog excitation, nws cov electrons tuaj yeem zoo siab rau hauv cov khoom siv hluav taws xob, yog li muab cov silicon muaj peev xwm ua hluav taws xob. Silicon kuj tseem yog thermally conductive thiab tuaj yeem tswj xyuas thermal conductivity ntawm qhov kub thiab txias.
Cov khoom siv kho qhov muag ntawm silicon kuj yog ib qho ntawm nws cov khoom tseem ceeb ua cov khoom siv semiconductor. Lub siab refractive index thiab transmittance ntawm silicon ua rau nws dav siv nyob rau hauv photoelectric li.
