The field effect at the bismuth film/electrolyte interface

It is found that the conductance vs. potential curve of thin bismuth films shows a minimum in the potential range corresponding to a positive charge of the surface. Taking into account the semi-metallic nature of bismuth film this result can be explained in terms of a transition from predominantly e...

Description
Summary:It is found that the conductance vs. potential curve of thin bismuth films shows a minimum in the potential range corresponding to a positive charge of the surface. Taking into account the semi-metallic nature of bismuth film this result can be explained in terms of a transition from predominantly electron (at negative charge of the surface) to predominantly hole (at positive charge) surface conductance.
