Silicon barium yog aBinary sib txuasntawm barium (ba) thiab silicon (si), feem ntau tshwm sim li aGrey Crystalline KhoomCov. Nws muaj nyob rau hauv ntau cov ntaub ntawv stoichiometric, nrogBasi₂ ua qhov tseem ceeb tshaj plaws.

Cov yam ntxwv tseem ceeb:

✔ Siab melting point(~ 1,200 degree)
✔ Cov yam ntxwv semiconductor(tuneable bandgap)
✔ Zoo Deagidizing Muaj Peev Xwm
✔ Reforeive nrog dej(tsim cov khoom silane)

Cov Ntawv:

Hmoov(rau hnub ci hlwb, tsho xim)

Lumps(metallurgical apps)

Kev yaum(siab {- purity semiconductor siv)

Vim li cas thiaj muaj silicon Barium tseem ceeb?

1. Superior Hlau & Ntau Lawm 🏗️

Hauv metallurgy, silicon barium ua haujlwm raws li lub zog:

Deagidizer (tshem tawm oxygen los ntawm Molten Hlau)
Desulfurizer (txo cov txiv lws suav)
Nodularizing tus neeg sawv cev (txhim kho cov kav hlau lub zog)
Qhov tshwm sim: tshuaj ntxuav, muaj zog dua, thiab cov hlau ntxiv.

2. Tom ntej -} pa secar zog ☀️

Basi₂ tawm los ua lub teeb -}}}} absor absor absor absor absor- Zaj duab xis hnub ci raws li nws:

Kev khi qib zoo tshaj plaws (1.3 EV, ze rau qhov zoo tagnrho rau photovoltaics)
Cov kev haum xeeb cov coefficient
Tus nqi qis dua vs. ib txwm silicon hlwb
Tej zaum: yuav ua rau lub zog hnub ci zog ntau dua thiab muaj txiaj ntsig.

3. Txawj siv hluav taws xob tau zoo & semiconductors 💻

Cov kws tshawb nrhiav tau tshawb fawb Basi₂ rau:

Cov khoom siv thermoelectric (khib nyiab sov rov qab)
Photodetectors (infrared sensors)
Quantum Dot Daim Ntawv Thov

4. Hydrogen tiam ⚡

Thaum muaj kev cuam tshuam nrog dej, basi₂ ua rau seem nyiav (Sih₄), muaj cov roj tseem ceeb rau:

Hnub Ci Vaj Huam Sib Luag Raug
Semiconductor Doping
Hydrogen Fes Tshawb Fawb
