LaHfO3

LaHfO3 is a rare-earth hafnate ceramic compound combining lanthanum and hafnium oxides, belonging to the perovskite family of high-refractive-index materials. This material is primarily investigated for advanced dielectric and optical applications, particularly in gate dielectrics for next-generation semiconductor devices and as a high-k material alternative to traditional silica in integrated circuits. Its high thermal stability, low leakage current characteristics, and compatibility with silicon processing make it a candidate for scaling beyond conventional gate oxide limits in microelectronics, though it remains largely in research and early development stages rather than mainstream production use.
