What are the possibilities of measuring whether the material is more or less "p-type"? (for example conducting polymer and reduced graphene oxide and the composite)
Hall effect measurement.

Hall or Seebeck coefficient should be the one if you don't want to mess around with atmosphere too much. Otherwise conductivity as a function of oxygen partial pressure should give some answers. It all depends on the material.
Dear Dunst,
Hall measurement is the best and versatile tool for meausring the p type and n type.
What exactly can be measured by Mott Schottky experiment. Some of publications show that Mott Schottky plot gives doping density by slope of the straight line and
flatband potential by intercept but here: https://www.infona.pl/resource/bwmeta1.element.elsevier-da007755-425e-3eac-bda1-136c13417028 this experiment is conducted only for BiVO4, not composite with polymer. Here https://hal.archives-ouvertes.fr/hal-01111490/document this experiment is conducted for composite but Csc - space charge layer capacitance indicate the capacitance of TiO2. When Mott Schottky plot is draw for composite, what does it mean? When I have different slopes of the straight line it means that material X is more p-type than material Y?
