Good electron-hole conductor?

~~I think you need a conductor for which (carrier conc. x avg. mobility) is same for both electrons and holes. That kind of thing does not exist naturally~~

EDIT: Damn forgetful mind.

No, the type of charge carriers is independent of the field. You only need the field for diagnostic purposes. However I would be careful with the interpretation of the Hall coefficient in terms of nature of the charge carriers.

Especially in ferromagnetic materials. Magnetic fields don't penetrate ferromagnetic materials very well. So the "anomalous Hall effect" in iron may be caused by something other than the charge of the carrier. It may have something to do with the ferromagnetism.

Probably there should be some metal alloy with anomalously low effective mass of holes.
