Mea'ai Fa'avevela Fa'avela Sili Sili Sili Tulaga Maualuga Mo le MOCVD Ata Fa'aalia

Fa'amatalaga Puupuu:

Semicera ose fa'atau oloa fa'apitoa e fa'atauva'a ma mea fa'atau semiconductor. Matou te faʻamaoni i le tuʻuina atu o oloa maualuga, faʻatuatuaina, ma fou i le gaosiga o semiconductor, photovoltaic alamanuia ma isi faʻalapotopotoga faʻapitoa.

O la matou laina oloa e aofia ai SiC / TaC faʻapipiʻiina oloa graphite ma oloa sima, e aofia ai mea eseese e pei o le silicon carbide, silicon nitride, ma le alumini oxide ma isi.

I le avea ai o se tagata faʻalagolago, matou te malamalama i le taua o mea faʻaaogaina i le gaosiga o gaosiga, ma matou te tuuto atu i le tuʻuina atu o oloa e fetaui ma tulaga sili ona lelei e faʻamalieina ai manaʻoga o matou tagata faʻatau.

Auina imeli ia matou

Fa'amatalaga Oloa

Faailoga o oloa

Autu autu o le faʻavevela graphite:

1. tutusa o fausaga faamafanafana.

2. conductivity lelei eletise ma le mamafa eletise maualuga.

3. tete'e corrosion.

4. inoxidizability.

5. mama maualuga kemikolo.

6. malosi faʻainisinia maualuga.

O le lelei o le malosi lelei, maualuga le tau ma maualalo le tausiga. E mafai ona tatou gaosia le anti-oxidation ma le umi o le ola o le graphite crucible, graphite mold ma vaega uma o le graphite heater.
