More info

Lithium Aluminate (LiAlO2) Crystal Substrate is a tetragonal crystal material commonly used as a substrate for GaN and ZnO epitaxial growth. It has a relatively small lattice mismatch with these materials, which helps to reduce defects in epitaxial films. LiAlO2 also offers good thermal stability and chemical resistance, making it a suitable choice for high-performance optoelectronic applications. Due to its structural properties, it is considered an alternative to conventional substrates like sapphire in certain applications, including LEDs, laser diodes, and other semiconductor devices. Heeger Materials provides high-quality Lithium Aluminate Crystal Substrate for various advanced material research and industrial applications.
