· LuScO3

Lutetium scandium oxide (LuScO3) is a rare-earth ceramic compound belonging to the perovskite family of semiconductors. This material is primarily investigated in research settings for its potential as a high-κ dielectric and as a substrate or buffer layer in advanced microelectronics and thin-film optoelectronic devices, where its lattice properties and thermal stability offer advantages over conventional oxide alternatives.
