A PhD student requested a quote for the following.
I'm interested in doing a research on the optical properties of surface phonon polariton which can exist in polar materials such as 6H-SiC.
I'm looking for wafers with a diameter of about 2 inches.
Do you sell wafers of 6H-SiC in this size?
UniversityWafer, Inc. Replied:
I think you need semi-transparent SIC for optical application, please see below and here for diagram:
2", 6H, Semi-Transparent SiC for optical application.
Reference #224406 for specs and pricing.

Polar materials are materials in which the centers of positive and negative charges do not coincide, resulting in a permanent electric dipole moment. This means the material has a built-in asymmetry in charge distribution, which gives rise to interesting electrical and optical properties.
Permanent Dipole
Electrons are more concentrated around certain atoms or regions, creating a separation of charge.
Asymmetric Structure
Typically found in crystals without inversion symmetry, such as wurtzite or zinc blende structures.
Spontaneous Polarization
Even in the absence of an external electric field, these materials can maintain an internal electric field.
Strong Interaction with Light and Fields
Useful in nonlinear optics, piezoelectricity, and polaritonics due to their ability to interact with electric and electromagnetic fields.
