Silicon Ingot Production
A mono-crystalline silicon seed crystal is brought into contact with one end of a poly-crystalline silicon ingot in the ﬂ oat-zone (FZ) or zone melting process as schematically shown in Fig. 5. Starting from here, an RF coil melts a small region of the polysilicon which, after cooling down, forms mono-crystalline silicon

Silicon carbide particles induced thermoelectric
Silicon carbide (SiC) is a promising candidate for thermoelectric appliions because SiC has a large Seebeck coefficient and a low electrical resistivity [9 , 10]. However, SiC exhibits poor thermoelectric performance owing to its high thermal conductivity (~120 W m −1 K−1) [11, 12], despite having a high power factor. In this regard,

US5718760A - Growth of colorless silicon carbide crystals
Large single crystals of silicon carbide are grown in a furnace sublimation system. The crystals are grown with compensating levels of p-type and n-type dopants (i.e., roughly equal to levels of the two dopants) in order to produce a crystal that is essentially colorless. The crystal may be cut and fashioned into synthetic gemstones having extraordinary toughness and hardness, and a brilliance
Silicon Wafer Processing | How Are Silicon Wafers Made?
To grow an ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. Once the polycrystalline and dopant coination has been liquefied, a single silicon crystal, the seed, is positioned on top of the melt, barely touching the surface. The seed has the same crystal orientation required in the finished ingot.
