The influence of doping degree on the structural characteristics of bismuth films doped with tellurium in the concentration range 0.005-0.150 at. % Te and the thickness range 0.3-0.7 (m is studied at present article. Authors have established that an increase of the doping degree with tellurium in bismuth films leads to a significant decreasing of the growth figures. The weak influence of annealing on the crystallite size of bismuth films doped with tellurium indicates their high temporal stability of the structure.
