Epitaxial growth of MgB{sub 2}(0001) thin films on magnesium single-crystals

Phase-pure MgB{sub 2} thin films have been grown in ultrahigh-vacuum conditions on Mg(0001) and Mg(1010) at low-temperature (185-220 deg. C) via molecular beam epitaxy. By depositing B on the Mg substrate a maximum film thickness of {approx}4 ML can be achieved, while thicker layers can be obtained by codeposition of Mg and B. Thick films grown on Mg(0001) show a sharp hexagonal low energy electron diffraction pattern, as well as the angle resolved photoemission band structure and x-ray absorption features of MgB{sub 2}(0001) surface. Poor long-range order can be achieved by codeposition on Mg(1010). This method allows important in situ measurements, may enable the controlled doping of MgB{sub 2}, and could be used to realize MgB{sub 2}-based superconducting devices.
