Abstract: The paper demonstrates for the first time the possibility of using aluminum nitride–scandium as an effective piezoelectric material in composite acoustic resonators on synthetic diamond substrates. Composite resonators based on an Al/(Al, Sc)N/Mo/(100) diamond piezoelectric… read more here.
