This work studies the effect of a transverse electric field on the resistance of bismuth thin films.
The existence of an electric field effect in bismuth thin films on mica and polyimide has been experimentally
confirmed. The study obtained experimental dependences of resistance on the transverse electric field strength
for bismuth films of various thicknesses on mica and polyimide. It also revealed changes associated with
a decrease in the thickness of the film and the material of the used substrate. A qualitative interpretation
of the observed effect was given based on the analysis of changes in the mobility of free charge carriers in films
depending on the direction of the electric field, as well as the thickness of the film and the substrate material.
