FAQs

Q1 What are the types of Sapphire Substrates?

Sapphire substrates come in several crystallographic orientations, including:

C-plane (0001): Most commonly used for devices requiring high optical clarity and high-quality epitaxial growth.
R-plane (1-102): Preferred for certain optical and electronic applications.
M-plane (1-100): Less commonly used but suitable for specific growth orientations.

Q2 Why is Sapphire preferred for LED applications?

Sapphire is preferred in LED applications due to its ability to provide a high-quality, smooth surface for epitaxial growth of semiconductor layers. Its high thermal conductivity helps dissipate heat efficiently, and its mechanical strength ensures durability and resistance to damage.

Q3. Can Sapphire Substrates be used in high-temperature applications?

Yes, sapphire substrates are well-suited for high-temperature applications. Their high melting point (around 2,000°C) makes them ideal for use in environments where high temperatures are common, such as high-power electronics and aerospace components.
