About This Product

■Since the 1980s, our company has continued to contribute to the advancement of science and technology, including providing SrTiO3 and sapphire substrates as substrates for high-temperature superconducting thin films and GaN.

For epitaxial growth substrates, the presence or absence of crystal lattice distortion on the outermost surface is important, as well as crystallinity, smoothness and flatness of the substrate surface. Based on our accumulated technology over many years, we carry out integrated production in-house, from crystal growth (with the exception of some crystals) to processing.Using high-precision processing technology, we can finish the surface of a high-quality crystal substrate without any processed distortion layers. I am. We provide oxide crystal substrates that are ideal for epitaxial growth of dielectrics, superconductors, compound semiconductors, etc.

■Neodygalate

NaGaO3 (110) is widely used as a substrate for epitaxial growth of magnetic materials, ferroelectric materials, and superconductors. The (011) plane is also attracting attention as an epitaxial substrate for GaN because its lattice length and symmetry are close to those of GaN (0001). Our company performs integrated production from crystal growth using the CZ method to substrate processing. Please feel free to use it for your research.
