Abstract
A layer system especially for forming SAW devices thereon is proposed comprising a monocrystalline sapphire substrate having a first surface and a crystalline piezoelectric layer comprising MN, deposited onto the first surface, and having a second surface. As a first surface a crystallographic R-plane of sapphire is used enabling an orientation of c-axis of the piezoelectric layer parallel to the first and second surfaces.
