Dear Colleagues,

would appreciate if you could recommend references, if such a theory exits, for the following question.

Let $A$ be an Abelian scheme over $\text{Spec}(R)$, where $R$ is a subring of an algebraic closure of $\mathbb{Q}_{p}$ ($p$-adic field). Is there any reference which describe group scheme $A[p]$ as it does the theory of the DieudonnÃ© modules for schemes over fields or over a ring of characteristic zero with $p$ being a nilpotent.
