II-VI Substrates for Research and Production

II-VI Wafers Used for Bragg Mirror

A postdoc at a college of optics and photonics requested the following quote:

Are you able to deposit ZnSe or CdS, or CdSe, or GaAs in a dielectric stack on glass or sapphire. The thickness of the semiconductor would be between 150 and 200nm. The idea is that the semiconductor goes into the center of a Bragg mirror, basically.

We would need a quantity of 1 or 2, the size would preferably be around 1 inch in diameter, but we could work with as little as 0.5 inch diameter. 

At first, we would need one of these semiconductors on a transparent substrate.

Further down the line, we would like Bragg mirrors on both sides on a transparent substrate.

What Substrates are II-VI Familiy of Material?

II-VI substrates are materials composed of elements from Group II (e.g., zinc, cadmium) and Group V (e.g., phosphorus, arsenic) of the periodic table. These substrates find extensive use in semiconductor technology. Here are some examples:

1. Zinc Sulfide (ZnS): Used in various optical applications, including lenses, windows, and infrared optics. It is also used as a substrate for thin-film deposition processes.

2. Zinc Selenium (ZnSe): Employed in blue and green laser diodes, infrared optics, and high-power solid-state lasers.

3. Zinc Telluride (ZnTe): Used in infrared optical components, as well as in semiconductor devices like photovoltaic cells.

4. Cadmium Sulfide (CdS): Commonly used in thin-film solar cells, photodetectors, and photoresistors due to its semiconducting properties.

5. Cadmium Telluride (CdTe): Widely used in thin-film solar cells, CdTe has gained attention for its potential in low-cost, high-efficiency solar energy conversion.

6. Mercury Cadmium Telluride (HgCdTe): This compound is used in infrared detectors, including those used in night vision devices and thermal imaging cameras.

   A Silicon MEMS-on-CMOS Platform researcher requested a quote for the following:

    I need MBE HgCdTe grown on CdTe or GaAs or Si of any bandgap, size or thickness.

   Cadmium Selenide (CdSe): A PhD candidate requested a quote for CdSe for Raman Samples was looking for a piece of high quality, single crystalline CdSe sample as Raman standard.  I don't need a big piece.  I am looking for the best price. Reference #156842 for specs and pricing.

These are some examples of II-V substrates, each with its own unique properties and applications in semiconductor technology.
