Kinda answered my own question with some searching - looks like p type has lots of electrons, n type has lots of holes, and graphene oxide (GO) makes an excellent and simple to use n type material.

Graphene can be modified by changing its topology to be p or n, but GO is n by default. Do electron and hole features have to match in these constructions?

I think that's backwards: P-type has more holes than electrons, n-type has more electrons than holes.
