NdGaO3 Substrate

NdGaO3 is a new type of substrate developed in the past decade, mainly used as a substrate for epitaxial film growth of high-temperature superconductors (such as YBCO) and magnetic materials. Because the lattice mismatch between NdGaO3 and YBCO is very small (~0.27%), and there is no structural phase change, a good quality film can be epitaxially grown on the NdGaO3 substrate.

OST Photonics offers high quality NdGaO3 substrates for researchers and industries. Crystal orientation, size and thickness can be customized according to your requirements.
