Effect of Sr doping on structure, morphology, and transport properties of Bi2Se3 epitaxial thin films
Effect of Sr doping on structure, morphology, and transport properties of Bi2Se3 epitaxial thin films
We report molecular beam epitaxy growth of Sr-doped Bi2Se3 films on the (111) BaF2 substrate, aimed to realize unusual superconducting properties inherent to SrxBi2Se3 single crystals. Despite the wide range of the compositions, we do not achieve superconductivity. To explore the reason for this, we study the structural, morphological, and …
