Product Parameters

• Temperature:

  The temperature gradient and the temperature of the melt are critical. Low temperature gradients (5-15 °C/cm) are often preferred to maintain a planar melt-solid interface and reduce strain. 

   
• Growth Rate:

  Slow growth rates (0.1-0.5 mm/h) are generally necessary to avoid constitutional supercooling and interface breakdown. 

   
• Atmosphere and Pressure:

  The type of gas (e.g., argon) and the pressure within the furnace affect the crystal growth process. 

   
• Rotation Rate:

  Rotating the crucible and/or the seed crystal can help maintain a stable melt and promote uniform crystal growth. 

   
• Power:

  The power applied to the heating elements (e.g., laser power in laser-heated methods) needs to be carefully controlled. 

   
• Feed Rod and Seed Rod Speed:

  The speed at which the feed rod (source material) and seed rod (seed crystal) are translated or rotated influences the growth process. 

   
• Crucible and Crystal Radius:

  The dimensions of the crucible and the growing crystal are important factors in determining the overall size and shape of the crystal. 

   
• Magnetic Field (for some methods):

  In techniques like the Czochralski method, a magnetic field can be applied to control melt convection. 

   
• Material Properties:

  The specific properties of the material being grown (e.g., melting point, thermal conductivity) will influence the optimal parameter settings. 

   

Examples of Parameter Adjustments:

• Czochralski (CZ) Method:

  Parameters like crucible and crystal rotation rates, pulling rate, and the strength and configuration of the magnetic field are adjusted to control the growth of silicon and other semiconductor crystals. 

   
• Image Furnace Growth:

  Parameters like the growth rate, temperature gradient, and the power of the heating lamps are adjusted to grow crystals like CrB2. 

   
• Modified Furnace Growth:

  Specific parameters like temperature gradients and thermal profiles are adjusted to grow crystals like AgGaS2. 

   
• Floating Zone (FZ) Method:

  Parameters like laser power, feed rod and seed rod speeds, and the stability of the molten zone are adjusted to grow crystals like Nd:YAG. 

   

Importance of Parameter Control:

• Crystal Quality:

  Properly adjusted parameters lead to high-quality single crystals with fewer defects and desired properties. 

   
• Growth Stability:

  Stable growth parameters prevent instabilities that can lead to polycrystal formation, cracking, or other defects. 

   
• Reproducibility:

  Consistent parameter settings ensure that crystals can be grown reproducibly with the same characteristics.
