LaAlO3 single crystal-1

PAM XIAMEN offers LaAlO3 Single Crystal Substrat

Lanthanum aluminate (LaAlO3) single crystal substrate is the large-scale high-temperature superconducting film,which has good match with YBaCuO and other high temperature superconductor materials and lattice, low dielectric constant and small microwave loss, so LaAlO3 substrate is suitable for making high temperature superconductor microwave electronic devices (such as high temperature superconductor microwave filter in remote communication).
