In this study we have characterized the mechanical and electrical properties of Bi 2 Te 3 thin films prepared by co-sputtering method. The film structure and morphology were revealed using the X-ray diffraction and scanning electron microscopy (SEM). Thickness of the deposited films was measured using SEM observation after FIB (Focused Ion Beam) milling, and the surface roughness of the films was analyzed using AFM (atomic force microscopy). Electrical transport properties were measured with a Hall effect measurement system, while the mechanical properties were evaluated using nanoindentation test method. Results showed that Bi 2 Te 3 thin films have amorphous structure at lower film thicknesses, but as the thickness increases the structure becomes polycrystalline. Surface roughness and crystal size of the films increased with increase in substrate temperature. Films showed higher elastic modulus and hardness values compared to those of the bulk Bi 2 Te 3 alloy. The electrical transport properties of the films were also affected by the substrate temperature.

Main Effects

ABSTRACTThe main effects of the interaction of accelerated ions with polymeric targets are critically reviewed. The possibility of a relatively reduced heating of polymer during ion beam bombardment is analyzed. Experimental data pointing towards various radiation-induced modifications in polycarbonate (free radicals production, modifications of the energy gap) are discussed.
