Abstract
A graphene laminate includes a first piezoelectric material layer having a negatively-charged surface and a positively-charged surface, a first graphene layer under the first piezoelectric material layer, the first graphene layer contacting the positively-charged surface of the first piezoelectric material layer, a second graphene layer underlying the first graphene layer, and a second piezoelectric material layer under the second graphene layer, the second piezoelectric material layer having a negatively-charged surface and a positively-charged surface, the negatively-charged surface contacting the second graphene layer.
