Annotation The paper reports our experimental data on growth, morphology, optical and electrophysical properties of NaBiTe2 thin films grown by thermal evaporation in vacuum. The structural characteristics and electric field-induced properties of semiconductor NaBiTe2 films with Cr contacts are investigated. Room-temperature time dependence of the current flowing through the investigated structures under applied electric field is also discussed. The influence of some aggressive atmospheric impurities on NaBiTe2 films characteristics is described for the first time.
