Isn't graphene a high quality p type material as well? What makes a material p or n?

Isn't graphene a high quality p type material as well?
What makes a material p or n?
- robbedpeter 5y agoKinda 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?
- steve_b 5y agoI think that's backwards: P-type has more holes than electrons, n-type has more electrons than holes. https://simple.wikipedia.org/wiki/P-type_semiconductor https://simple.wikipedia.org/wiki/P-type_semiconductor (property 2)
